How to Link Microsoft Account to Digital License in Windows 11 & 10 (Complete 2026 Guide)

All steps in this guide are verified against official Microsoft activation documentation and tested on Windows 11 24H2 and Windows 10 22H2 as of June 2026.

Most people never think about how to link Microsoft account to digital license in Windows — until it’s too late. You replace your motherboard, reinstall Windows, or buy a new PC, and suddenly your copy of Windows won’t activate. Buying a new Windows license costs $150 or more. Linking your Microsoft account to your Windows digital license takes two minutes and prevents that problem entirely.

This is the most complete guide on this topic. It covers the standard setup, both Windows 11 and Windows 10 separately, the hardware change scenarios, and, critically, what to do if you have already changed hardware without linking first. That emergency recovery section does not exist in any other guide on this subject.

Quick Check — Are You Already Done? Go to Settings → System → Activation (Windows 11) or Settings → Update & Security → Activation (Windows 10). If the screen says: “Windows is activated with a digital license linked to your Microsoft account”, you are already set. No further action needed.If it says: “Windows is activated with a digital license,” your license is active but not yet linked. Follow this guide.

Already Changed Hardware Without Linking? Do Not Panic: Your recovery options depend on your license type. Jump directly to the Emergency Recovery section, which has specific steps for your exact situation.

What Is a Windows Digital License: And Why Linking It Matters

This section explains what a Windows digital license is, how it differs from a product key, and exactly why linking your Microsoft account prevents costly reactivation failures.

A Windows digital license (formerly called a digital entitlement) is a method of Windows activation that stores your licence information on Microsoft’s servers, tied to your device’s unique hardware signature. Unlike the old 25-character product key printed on a sticker, you cannot lose a digital licence; it does not physically exist anywhere on your machine.

The problem is that a digital licence is tied to your hardware, not to your identity. When you replace a major component — especially the motherboard — Windows generates a new hardware signature. Microsoft’s servers no longer recognise your device, and Windows is deactivated. Without a linked Microsoft account, recovering that activation requires contacting Microsoft support, which can take hours.

When you link your Microsoft account to your Windows digital licence, activation becomes tied to your identity rather than just your hardware. After any hardware change, you can run the Activation Troubleshooter, sign in with your Microsoft account, and reactivate in under two minutes — with no product key required.

Quick Tip: The difference between a hardware-locked licence and an account-linked licence can mean the difference between a seamless upgrade and spending $150+ on a new Windows copy. Two minutes of setup now protects that investment permanently.

OEM vs Retail vs Volume License: Which One Can You Link?

Before following any steps, confirm your licence type — because not every Windows licence can be linked to a Microsoft account, and one type cannot be transferred at all.

License Type	How You Got It	Can You Link?	Can You Transfer?	What To Do
Retail	Bought a box/USB from a store, or purchased Windows.com	✅ Yes	✅ Yes — new hardware	Link your account; use Activation Troubleshooter after hardware changes
Digital Upgrade	Upgraded free from Windows 7/8/10	✅ Yes	❌ Tied to original hardware	Link your account; note transfer limitations apply
OEM	PC came with Windows pre-installed (Dell, HP, Lenovo etc.)	✅ Yes (linking)	❌ No — stays with original motherboard	Link for easier reactivation; but cannot move to a new PC
Volume / KMS	Provided by an employer, school, or IT department	❌ No	N/A	Contact your IT department — personal account linking is not supported

Critical OEM clarification: An OEM licence is permanently tied to the original motherboard. Linking it to a Microsoft account helps with reinstallation on the same machine. but it does NOT make it transferable to a completely different PC. If you replace the motherboard on an OEM machine, you may need to purchase a new licence regardless of account linking.

Quick Tip: Not sure which licence type you have? The next section shows you how to check in 30 seconds using a single command.

Check Your License Type in 30 Seconds

This section shows you the fastest and most reliable method to confirm your exact Windows licence type before making any changes — a step every other guide on this topic skips.

Open an elevated Command Prompt (search for ‘cmd’, right-click, and select Run as administrator) and type the following command:

slmgr /dlv

Press Enter. A window will appear with detailed licence information. Here is what to look for:

Field in Output	What It Tells You	What You Need to See
License Type	Your licence category	RETAIL = fully transferable. OEM_DM = machine-bound. VOLUME_KMS = cannot link
License Status	Current activation state	Licensed = activated. Notification = not activated
Product ID	Your Windows edition	Confirms Windows 10 or 11 Home / Pro / Enterprise

If the License Type field shows RETAIL, your licence is fully transferable and benefits most from account linking. If it shows OEM_DM, linking still helps for reinstallation on the same machine but won’t enable hardware transfers. If it shows VOLUME_KMS or VOLUME_MAK, stop here — account linking is not available for Volume licences.

Quick Tip: If the slmgr /dlv window disappears instantly, the command ran without admin privileges. Right-click Command Prompt and choose ‘Run as administrator’ before trying again.

Prerequisites Before You Start

Three specific requirements must be met before the ‘Add an account’ option appears in your Activation settings. Missing any one of them is why most users hit a wall.

• 1 — Administrator Account: You must be signed into Windows with an administrator account, not a standard user account. To check, go to Settings → Accounts → Your Info. It should say ‘Administrator’ under your name.
• 2 — Active Internet Connection: Microsoft verifies your credentials against its servers in real-time during the linking process. The connection must be live — not just connected but actually able to reach Microsoft’s servers.
• 3 — Already Activated Windows: Your copy of Windows must already be activated before you can link an account. You cannot link to a licence that does not yet exist.

To confirm your activation status, go to Settings → System → Activation (Windows 11) or Settings → Update & Security → Activation (Windows 10). Under the Activation state, you should see Active. If you see ‘Not activated’ or an error code, resolve the activation issue before proceeding.

Do This BEFORE Your Hardware Upgrade: Once you replace the motherboard without linking your Microsoft account, your recovery options are significantly more limited. This takes 2 minutes now and saves hours — or $150+ — later. If you are planning a hardware upgrade in the next few days, complete the linking process right now before reading anything else.

What Hardware Changes DO and DON’T Trigger Deactivation

Not every hardware upgrade affects your Windows activation. This table gives you the exact answer for each component — the specific information that users search for, but no competing guide provides clearly.

Component	Triggers Deactivation?	Notes
Motherboard	✅ YES — almost always	Treated as a new device. Most critical component. Linked MSA account is essential for recovery.
CPU	⚠️ SOMETIMES	Replacing CPU alone rarely triggers deactivation. Pairing with a new motherboard always does.
RAM (memory)	❌ NO	RAM changes are invisible to the Windows activation system. Safe to upgrade freely.
GPU (graphics card)	❌ NO	GPU is not part of the hardware signature. Upgrade, replace, or remove freely.
Storage / SSD / HDD	⚠️ SOMETIMES	Replacing the primary OS drive and reinstalling Windows counts as a new activation event.
Network Card / NIC	❌ NO	Network hardware is not a primary activation component in modern Windows.
Display / Monitor	❌ NO	External display changes have no effect on Windows activation whatsoever.
USB / PCIe Expansion Cards	❌ NO	Add-in cards are not registered in the hardware signature.

The rule of thumb: If the component is on the motherboard or IS the motherboard, it likely affects activation. Peripheral components (RAM, GPU, storage, networking) are generally safe. The motherboard is the highest-risk single component — always link your Microsoft account before touching it.

Quick Tip: If you are upgrading only RAM or a GPU, you do not technically need to link your account for this specific upgrade. However, linking is still recommended as a general good practice before any major PC work.

How to Link Microsoft Account to Digital License in Windows 11

These are the numbered steps specific to Windows 11. The Settings navigation in Windows 11 differs from Windows 10 — separate paths are listed below. Do not skip the verification phase (Phase 3) after completing the steps.

Phase 1 — Confirm Your Account Type

1. Press Windows + I to open Settings.
2. Click Accounts in the left sidebar.
3. Check the top of the Accounts page. If you see your Microsoft account email address listed, skip to Phase 2. If you see ‘Local Account’, continue to the next step.
4. To switch to a Microsoft account: still in Accounts, click Your Info, then click Sign in with a Microsoft account instead. Follow the on-screen prompts.
5. Restart your PC after switching from local to a Microsoft account before proceeding.

Phase 2: Link the Digital License

6. Press Windows + I to open Settings.
7. Click System, then click Activation.
8. Look at the Activation state. It should read Active.
9. Below the Activation state, look for the text: “Windows is activated with a digital license.” If you see this, the link has not yet been made — proceed.
10. Click Add an account (this button appears when you are signed into Windows with a Microsoft account and the licence is not yet linked).
11. A Microsoft account sign-in window may appear. Sign in with the same account you use for Windows.
12. Wait for the page to refresh. The activation text should now read: “Windows is activated with a digital license linked to your Microsoft account.”

Phase 3: Verify the Link

13. Remain on the Activation page and confirm the text reads “Windows is activated with a digital license linked to your Microsoft account.”
14. Open a browser and go to account.microsoft.com/devices and sign in with the same Microsoft account.
15. Click the Devices tab. Your current PC should appear by name. If it is listed, Microsoft’s servers have confirmed the link. You are protected.

How to Link Microsoft Account to Digital License in Windows 10

Windows 10 uses a different Settings navigation than Windows 11. If you are on Windows 10, follow these specific paths — do not use the Windows 11 steps above, as the menu structure differs.

Phase 1 — Confirm Your Account Type (Windows 10)

16. Press Windows + I to open Settings.
17. Click Accounts.
18. On the Your Info page, check whether your Microsoft account email is shown. If it shows ‘Local Account’, click Sign in with a Microsoft account instead and complete the login.
19. Restart your PC after switching account types.

Phase 2 — Link the Digital License (Windows 10)

20. Press Windows + I to open Settings.
21. Click Update & Security.
22. Click Activation in the left sidebar.
23. Confirm the activation status reads Windows is activated with a digital license.
24. Click Add an account below the activation status text.
25. Sign in with your Microsoft account when prompted.
26. The activation status should now update to: “Windows is activated with a digital license linked to your Microsoft account.”

Windows 11 vs Windows 10 — Navigation Paths at a Glance

Action	Windows 11 Path	Windows 10 Path
Open Activation settings	Settings → System → Activation	Settings → Update & Security → Activation
Check account type	Settings → Accounts → Your Info	Settings → Accounts → Your Info
Switch to Microsoft account	Settings → Accounts → Your Info → Sign in with Microsoft	Settings → Accounts → Your Info → Sign in with Microsoft
Add account to link licence	Activation page → Add an account	Activation page → Add an account
Verify link success	Activation page shows ‘linked to your Microsoft account’	Activation page shows ‘linked to your Microsoft account’

How to Verify the Link Was Successful

Completing the steps is not enough — confirm the link worked from three angles before trusting it. Only the third check confirms the link on Microsoft’s servers, not just locally.

Verification Method 1 — Activation Settings Screen

Go to Settings → System → Activation (Win11) or Settings → Update & Security → Activation (Win10). The activation text must read exactly: “Windows is activated with a digital license linked to your Microsoft account.” If it reads ‘Windows is activated with a digital license’ without the ‘linked to your Microsoft account’ part, the linking step was not completed.

Verification Method 2 — slmgr /xpr Command

For a command-line confirmation, open an elevated Command Prompt and run:

slmgr /xpr

This returns your activation expiry status. A permanently activated Windows installation returns ‘The machine is permanently activated.’ This confirms activation is valid, though not specifically account-linked.

Verification Method 3 — account.microsoft.com/devices (Server-Side Confirmation)

Open a browser and navigate to account.microsoft.com/devices. Sign in with the Microsoft account you used in the linking steps. Under the Devices tab, locate your current PC by its name. If your PC appears in this list, Microsoft’s servers have confirmed the digital licence is tied to your account. This is the definitive server-side check — if it shows here, the link is real.

Quick Tip: While on account.microsoft.com/devices, look for any old or duplicate device entries (e.g., multiple entries named ‘Desktop-User’ from previous installs). Remove any entries you no longer own or use. Stale entries can interfere with reactivation. See the Ghost Device section below.

BitLocker Warning — Back Up Your Recovery Key Before Hardware Changes

If your drive is encrypted with BitLocker, there is one additional critical step before any hardware change. Skipping it can lock you completely out of your own encrypted drive.

BitLocker Alert — Read Before Any Hardware Change: If your drive is BitLocker-encrypted, switching to a Microsoft account changes how Windows stores your recovery key. Before any hardware change, go to Settings → Privacy & Security → Device Encryption (Windows 11) or Control Panel → BitLocker Drive Encryption (Windows 10). Click ‘Back up your recovery key’ and save it to your Microsoft account AND a separate USB drive or printed document. A hardware change without a backed-up BitLocker key can make your encrypted data permanently inaccessible.

When you link your Microsoft account to your Windows digital licence, BitLocker’s recovery key becomes associated with that Microsoft account. After a hardware change, Windows may trigger a BitLocker recovery prompt on first boot. If you have your recovery key saved at account.microsoft.com/devices, you can retrieve it immediately. Without it, you cannot access your encrypted data.

Quick Tip: To check if BitLocker is active: open Command Prompt as administrator and run ‘manage-bde -status’. If it shows ‘Fully Encrypted’ or ‘Protection On’, you have an active BitLocker setup that needs a backed-up recovery key.

The Ghost Device Problem — Clean Up Old Devices Before Upgrading

One of the most common silent causes of reactivation failure after a hardware change is a stale device list on your Microsoft account. This section explains what Ghost Devices are and how to remove them before they block your next upgrade.

What is a Ghost Device? Every time you link a Windows installation to your Microsoft account, that device registers in your account’s Devices dashboard at account.microsoft.com/devices. If you have reinstalled Windows multiple times, or owned several PCs, you may have multiple entries for devices that no longer exist — some possibly sharing names with your current PC.

When you run the Activation Troubleshooter after a hardware change, it asks you to select which device you are trying to activate. If there are multiple stale entries with similar names, Windows may attempt to reactivate the wrong device — causing the troubleshooter to fail silently.

How to Remove Ghost Devices

27. Go to account.microsoft.com/devices in your browser and sign in.
28. Under the Devices tab, review every listed PC.
29. For any device you no longer own or use, click the device name, then click Remove device.
30. Confirm the removal. Removed devices can no longer use your account credentials for reactivation.
31. Leave only your current, active devices in the list.

Do this cleanup BEFORE any hardware change, not after. A clean device list makes the Activation Troubleshooter reliable and fast.

Emergency Recovery — What to Do If You Didn’t Link Before the Hardware Change

This is the section no other guide provides. If you have already changed hardware without linking your Microsoft account first, your recovery path depends entirely on your licence type. Follow the correct route below.

Emergency Recovery — Identify Your Route First: Run slmgr /dlv in an elevated Command Prompt to see your License Type before reading further. Your route depends on whether you have a Retail, OEM, or Volume licence. Do not call Microsoft support yet — exhaust the routes below first.

Your Situation	License Type	Step to Take
Changed motherboard; Windows won’t activate; have linked MSA	Retail	Run Activation Troubleshooter → ‘I changed hardware’ → sign in → select device → activate
Changed motherboard; Windows won’t activate; never linked MSA; have Retail key	Retail	Go to Settings → Activation → Change product key → enter Retail key → activate
Changed motherboard; Windows won’t activate; no key, no linked MSA	Retail (no key)	Contact Microsoft Support at support.microsoft.com — chat agent can manually reactivate with proof of purchase
Changed motherboard; Windows won’t activate; OEM PC	OEM	OEM licence is tied to original motherboard. You likely need a new licence. Check Microsoft support for exceptions first.
Clean install; Windows won’t activate; have linked MSA	Retail	Skip product key at setup → connect internet → sign in with Microsoft account → activation happens automatically
Clean install; Windows won’t activate; no linked MSA	Retail or OEM	Enter product key during setup, OR use Activation Troubleshooter if you have a record of the old device in Microsoft account
Volume / KMS copy; hardware changed	Volume	Contact your IT department. Personal account recovery does not apply to Volume licences.

The Retail Key Emergency Path — Step by Step

32. Boot into Windows (even if it shows as ‘Not activated’ — activation errors do not prevent use).
33. Go to Settings → System → Activation (Win11) or Settings → Update & Security → Activation (Win10).
34. Click Change product key (or ‘Troubleshoot’ if available).
35. Enter your 25-character Retail product key and click Next.
36. If successful, Windows reactivates using your key. Now immediately link your Microsoft account using the Phase 2 steps from earlier in this guide to prevent this situation from recurring.

The Microsoft Support Path — When No Key Exists

37. Go to support.microsoft.com in your browser.
38. Click Get Support and select Windows → Activation.
39. Use the live chat option rather than phone for faster response times.
40. Explain that you have changed hardware on a Retail Windows installation and need manual reactivation. Provide your original purchase receipt, the Windows edition, and any order confirmation.
41. A support agent can look up your licence on Microsoft’s backend and manually reactivate. This process typically takes 15–30 minutes over chat.

Quick Tip: Take a screenshot of your current activation status screen before contacting support. It helps agents understand your exact situation faster.

How to Reactivate Windows After a Hardware Change (Activation Troubleshooter)

If you linked your Microsoft account before the hardware change, reactivation after swapping components is straightforward. This is the process.

42. Install your new hardware and boot into Windows normally.
43. Windows may show an activation error or the ‘Activate Windows’ watermark. This is expected — do not be alarmed.
44. Go to Settings → System → Activation (Win11) or Settings → Update & Security → Activation (Win10).
45. Click Troubleshoot below the Activation state.
46. The Activation Troubleshooter will launch. Select “I changed hardware on this device recently.”
47. Sign in with your Microsoft account when prompted.
48. A list of your registered devices will appear. Select your current PC from the list.
49. Click Activate. Windows verifies with Microsoft’s servers and reactivates — no product key entry required.

If the Activation Troubleshooter does not appear, your licence was not linked before the hardware change. Return to the Emergency Recovery section above for your specific path.

Quick Tip: The activation troubleshooter works best immediately after the hardware change. Running it within 24 hours of the upgrade gives the highest success rate. Delayed attempts occasionally encounter temporary server-side flags.

How to Sell or Transfer Your PC’s Windows License

When selling a PC with a linked Windows digital licence, you must follow specific steps to protect yourself and give the buyer a clean start — otherwise your Microsoft account remains tied to the hardware.

Step 1 — Remove the Device from Your Microsoft Account

50. Go to account.microsoft.com/devices and sign in.
51. Find the PC you are selling in the Devices tab.
52. Click the device name, then click Remove device and confirm.

Step 2 — Provide the Product Key If You Have It

If you have the original 25-character Retail product key (from a box, USB, or digital receipt), provide it to the buyer. They can enter it during Windows setup. If your licence was a digital upgrade or came with the PC, there is no separate key to provide — the licence is tied to the hardware.

Step 3 — Perform a Factory Reset

53. Go to Settings → System → Recovery (Win11) or Settings → Update & Security → Recovery (Win10).
54. Click Reset this PC and choose Remove everything.
55. This removes your personal data and Microsoft account association from the device. The buyer will set up Windows fresh.

Note on OEM licences: An OEM Windows licence is legally attached to the original hardware and transfers with it to the new owner. You do not need to do anything special for OEM licences — the licence follows the PC, not your account.

Troubleshooting — 8 Common Errors and Exact Fixes

If something went wrong during the linking process, this table covers every documented error with the exact resolution.

Error / Problem	Most Likely Cause	Exact Fix
‘Add an account’ button is missing	You are already signed in with a Microsoft account OR the licence is already linked	Check activation text — if it says ‘linked to your Microsoft account’, you are done. No action needed.
Volume License error appears	Your Windows copy is managed by a Volume/KMS server (school, work)	Account linking is not supported. Contact your IT department for assistance.
Sign-in loop keeps restarting	Local account was converted to MSA but restart was skipped	Restart your PC fully, then return to the Activation page to complete the Add an account step.
‘You need administrator privileges’	Current Windows account is a Standard User, not Administrator	Log out, log in as Administrator, then retry the linking steps.
Activation page shows ‘linked’ already but new PC not in devices dashboard	Browser cache or dashboard sync delay	Wait 15 minutes, hard-refresh the dashboard (Ctrl+F5), then recheck devices.
Windows shows ‘Not activated’ after hardware change	Hardware change without prior MSA link OR before troubleshooter runs	Follow the Emergency Recovery section. Use Activation Troubleshooter if MSA was linked.
‘Add an account’ fails with network error	No internet or Microsoft servers temporarily unreachable	Check internet connection; try again after 10 minutes; temporarily disable VPN if active.
Clean install does not auto-activate	Product key not entered during setup AND licence not linked to MSA	Skip product key screen during setup → connect to internet → sign in with your Microsoft account → activation resolves automatically if licence was previously linked.

Quick Tip: If none of the above resolves your issue, post in the official Microsoft community forums at answers.microsoft.com — searching your exact error message there surfaces solutions from Microsoft engineers and MVP community members.

Frequently Asked Questions

What does ‘link Microsoft account to digital license Windows’ actually do?

Linking creates a secondary association between your Windows digital licence and your Microsoft account identity. Without this link, your licence is tied only to your device’s hardware signature. With the link, Microsoft’s servers recognise your account as an authorised licence holder. This means after any hardware change, you can use the Activation Troubleshooter to reactivate Windows by signing in with your account — instead of hunting for a product key or paying for a new licence.

How do I know if my Windows digital license is already linked to my Microsoft account?

Go to Settings → System → Activation (Windows 11) or Settings → Update & Security → Activation (Windows 10). Read the activation status text carefully. If it says “Windows is activated with a digital license linked to your Microsoft account” you are already set. If it says ‘Windows is activated with a digital license’ without the ‘linked to your Microsoft account’ part, the link has not yet been made.

Can I link a digital license if I’m using a local account?

Not directly. You must first switch from a local account to a Microsoft account before the ‘Add an account’ option becomes available in Activation settings. Go to Settings → Accounts → Your Info and click ‘Sign in with a Microsoft account instead.’ After switching and restarting, the Add an account button appears in the Activation page. Windows 11 Home requires a Microsoft account during initial setup as of 2026, so most Home users are already using one.

What is the difference between a digital license and a product key?

A product key is a 25-character alphanumeric code that directly activates Windows. A Windows digital licence stores activation information on Microsoft’s servers and is tied to your device’s hardware — no key entry required. Digital licences are how Windows 10 and 11 activate on most modern PCs. You can have both: a product key you used once to originally activate Windows, and a digital licence stored on Microsoft’s servers as a result of that activation.

Can I transfer an OEM Windows license to a new PC?

No. An OEM licence is permanently tied to the original hardware it was first installed on — specifically the motherboard. Linking it to your Microsoft account does not make it transferable. If you build a new PC, you need a new Windows licence. The only exception is if you replace a failed motherboard with an identical model — Microsoft may allow reactivation in that specific scenario. Only Retail licences are fully transferable to new hardware.

Do I need to link my Microsoft account if I’m not changing any hardware?

Strictly speaking, no. If your PC hardware will never change, the digital licence tied to your hardware will continue to work without an account link. However, linking is still recommended as general protection against unexpected failures — motherboards fail, SSDs die, and having a linked account means a five-minute recovery instead of a multi-hour support call. The two minutes it takes to link is worth the peace of mind.

What happens to my Windows activation if I replace my motherboard?

Replacing the motherboard changes your device’s hardware signature. Microsoft’s activation servers no longer recognise your device as the one the licence was issued to, and Windows deactivates. If your Microsoft account was linked to the digital licence before the change, you can run the Activation Troubleshooter, select ‘I changed hardware recently’, sign in, and reactivate in minutes. Without that link, you may need a product key or Microsoft support intervention.

How do I reactivate Windows after changing hardware using my Microsoft account?

After installing new hardware and booting Windows, go to Settings → System → Activation → Troubleshoot. Select ‘I changed hardware on this device recently’, sign in with your Microsoft account, select your PC from the listed devices, and click Activate. This uses the account-linked digital licence to restore activation without requiring a product key. The activation troubleshooter handles the entire process automatically as long as the account was linked before the hardware change.

Does replacing RAM or GPU affect my Windows digital license?

No. RAM and GPU are not part of the Windows hardware signature used for activation. You can freely upgrade, replace, or remove memory and graphics cards without any risk to your Windows digital licence. The only component that almost always triggers deactivation is the motherboard. CPU replacements sometimes trigger it when paired with a new motherboard, but CPU-only swaps rarely affect activation.

What should I do if the ‘Add an account’ option is missing from Activation settings?

There are three possible reasons. First, you may already be linked — check if the activation text says ‘linked to your Microsoft account’. Second, you may be on a local account rather than a Microsoft account — switch in Settings → Accounts → Your Info. Third, you may have a Volume/KMS licence which does not support account linking — run slmgr /dlv to check. If none of these apply and the button is genuinely missing, try restarting, then check again from a fresh session.

How do I remove an old device from my Microsoft account?

Go to account.microsoft.com/devices in a browser and sign in. Under the Devices tab, click on the old device name and select Remove device. Confirm the removal. This deregisters the device so it no longer counts against your licence’s device associations. Always do this for PCs you no longer own, have sold, or have retired — stale entries can interfere with the Activation Troubleshooter when it needs to identify your current device.

Can I link my Microsoft account to a digital license on a Volume License (KMS) copy of Windows?

No. Volume/KMS licences are managed centrally by an organisation’s IT infrastructure and cannot be linked to personal Microsoft accounts. If you run slmgr /dlv and see VOLUME_KMS or VOLUME_MAK as the licence type, account linking is not supported for your copy of Windows. Contact your IT department for reactivation assistance after hardware changes.

What happens to my Windows license when I sell my PC?

For a Retail licence: remove the device from your Microsoft account at account.microsoft.com/devices, factory reset the PC, and optionally provide the buyer with the product key if you have it. The buyer can enter the key during setup. For an OEM licence: the licence is legally attached to the hardware and transfers with the sale. Factory reset the PC to remove your personal data. The new owner will need to set up Windows fresh, and activation should occur automatically as it is tied to the original hardware.

I changed my hardware without linking first — what are my options?

Your options depend on your licence type. If you have a Retail licence and still have the product key: enter it in Settings → Activation → Change product key to reactivate. If you have a Retail licence but no key: contact Microsoft Support via support.microsoft.com with proof of purchase — a support agent can manually reactivate. If you have an OEM licence: the OEM licence is tied to the original motherboard; replacing it may require purchasing a new Windows licence. See the Emergency Recovery section of this guide for step-by-step paths for each scenario.

Your Action Plan — Where to Start Based on Your Situation

Now that you understand how to link Microsoft account to digital licence Windows, here is your personalised starting point:

If you haven’t changed any hardware yet and want to protect yourself now:

• Do this today: Complete Phases 1–2 in the Windows 11 or Windows 10 steps above. It takes 2 minutes.
• Then verify: Check account.microsoft.com/devices to confirm server-side registration.
