How to Change Default Apps for File Types in Windows 11 and 10 (Every Method)

To change default apps for file types in Windows 11, follow this quick fix guide:

• Go to Settings: Open your Settings app (or press Win + I).
• Navigate to Default Apps: Click on Apps, then select Default apps.
• Search the File Extension: Type the specific file extension you want to change (e.g., .pdf, .jpg, .mp4) into the search box.
• Select the Result: Click on the file type result that appears.
• Choose Your App: Select your preferred application from the list.
• Confirm: Click Set default.

Windows decides which app opens every file on your computer based on the file extension. If PDFs keep opening in Microsoft Edge instead of Adobe Acrobat Reader, if videos launch in Movies and TV instead of VLC, or if a newly installed app took over file types you did not give it permission to own, you can fix all of that in under two minutes. Windows 11 and Windows 10 both provide multiple ways to change default apps for file types.

This Axeetech default apps guide covers every method from the fastest right-click fix to the enterprise Group Policy approach, plus a dedicated troubleshooting section for the two most common problems: defaults that refuse to stick and apps that refuse to appear in the picker.

Windows 11 Default Apps for Common File Types (Reference Table)

Before changing any default, check what Windows currently assigns to your file type and which free alternatives are available. This table covers the most commonly changed file types in Windows 11.

Extension	File Type	Windows 11 Default	Popular Free Alternatives
.pdf	PDF document	Microsoft Edge	Adobe Acrobat Reader, Foxit PDF, Sumatra PDF
.jpg .jpeg	JPEG image	Photos	IrfanView, Paint, GIMP
.png	PNG image	Photos	IrfanView, Paint.NET, GIMP
.mp4 .avi .mkv	Video	Movies and TV / Media Player	VLC, PotPlayer, MPC-HC
.mp3 .flac .wav	Audio	Windows Media Player	VLC, foobar2000
.html .htm	Web page	Microsoft Edge	Chrome, Firefox, Brave, Opera
.docx .doc	Word document	Word if installed / WordPad	LibreOffice Writer, WPS Writer
.xlsx	Spreadsheet	Excel if installed	LibreOffice Calc
.txt	Text file	Notepad	Notepad++, Visual Studio Code
.zip	Zip archive	File Explorer	7-Zip, NanaZip
.7z .rar	Compressed archive	None (requires separate app)	7-Zip, NanaZip, WinRAR
mailto:	Email link	Mail	Outlook, Thunderbird

Windows 11 stores your default app choice in a registry key called UserChoice. Each choice is tied to your specific user account, meaning changes on your account do not affect other users on the same PC. Every method in this guide applies only to the account you are currently signed into.

Tip: Windows 11 treats .jpg and .png as completely separate file types even though both are images. You can assign IrfanView to .jpg files and a different viewer to .png files independently. Most users set the same image viewer for all image formats, but the option to split them exists.

Method 1: Change Default Apps For File Types in Windows 11 Settings (Recommended)

Settings is the recommended path for most users. You can search by file extension to change one extension at a time, or search by app name to assign all supported extensions at once.

Change by file extension (for one specific extension):

1. Press Win+I to open Settings.
2. Click Apps in the left navigation panel.
3. Click Default apps on the right side.
4. In the search box near the top, type the file extension, including the dot, such as .pdf, .jpg, or .mp4.
5. Click the matching file type from the results list below the search box.
6. Select your preferred app from the picker that appears.
7. Click Set default to confirm.

Change by app name (to assign all supported extensions at once):

1. Open Settings > Apps > Default apps.
2. Type the app name in the search box, such as VLC Media Player or Adobe Acrobat.
3. Click the app in the results list.
4. Review the file types and protocols listed under the app.
5. Click Set default at the bottom to assign all supported file types to that app simultaneously. Or click individual extensions in the list to assign them one at a time.

Tip: The Set default button inside an app’s entry assigns every file type that app supports in one click. Clicking Set default on the VLC Media Player entry makes it the default for .mp4, .avi, .mkv, .mov, .flac, .mp3, and every other format VLC supports at once. This saves significant time compared to setting each extension individually through the extension search.

When you change audio and video defaults, you may also want to review your audio output device configuration. The AxeeTech guide on configuring your default playback device in Windows covers the steps to set your preferred speaker or headphone output alongside your media app defaults.

Method 2: Change Default Apps Using Right-Click Open With (Fastest)

The Open With context menu is the fastest way to change a default app when you already have a file of the type you want to reassign.

1. Right-click any file of the type you want to change in File Explorer.
2. Select Open with from the context menu.
3. Select Choose another app from the submenu or dialog.
4. Select your preferred app from the list that appears.
5. Check the box labeled “Always use this app to open [extension] files.”
6. Click OK to confirm the change.

Warning: Clicking Open with and selecting an app without checking the “Always use this app” checkbox opens the file once with that app but does NOT change the default. That checkbox is the key to making the change permanent. If the checkbox does not appear in the dialog on your version of Windows, use Method 1 through Settings instead.

Method 3: Change Default App via File Properties

File Properties provides an alternative route to the same app picker without using the context menu.

1. Right-click the file in File Explorer and select Properties.
2. On the General tab, look at the “Opens with” line near the top.
3. Click Change next to the currently listed app name.
4. Select your preferred app from the picker that appears and click OK.

This method works in both Windows 11 and Windows 10. The General tab also shows you the full file extension under “Type of file,” which is useful for confirming the exact extension before changing the default.

Method 4: Change Default Apps in Windows 10

Windows 10 uses a category-based model that is faster for changing major defaults like the browser, email client, or music player in a single click.

For major app categories (browser, email, music, video, photos, maps):

1. Open Settings > Apps > Default apps.
2. Scroll down to see the default app categories listed (Web browser, Email, Maps, Music player, Video player, Photo viewer).
3. Click the currently listed app under the category you want to change.
4. Select your preferred replacement from the picker.

For specific file extensions in Windows 10:

1. Open Settings > Apps > Default apps.
2. Scroll to the bottom and click “Choose default apps by file type.”
3. Find the extension in the alphabetically sorted list.
4. Click the app next to that extension and select your preferred replacement.

Tip: Windows 11 requires you to change each browser protocol individually. Making Chrome the default browser in Windows 11 means setting .html, .htm, the http: protocol, and the https: protocol each as separate steps. Windows 10 handles all of these with one click in the Web browser category. If you have recently upgraded to Windows 11 and find the browser change process frustrating, this is expected behavior.

Method 5: Enterprise Default Apps via Group Policy and DISM (IT Admins)

IT administrators managing multiple Windows PCs can export a reference set of file associations and deploy them across the organization using DISM and Group Policy.

1. Set up a reference PC with all desired file associations configured exactly as needed.
2. Open Command Prompt as administrator on that reference PC.
3. Run the DISM export command to create the associations XML file:

cmd

Dism /Online /Export-DefaultAppAssociations:C:\DefaultApps.xml

4. Open the Group Policy Management Console on your domain server.
5. Navigate to: Computer Configuration > Administrative Templates > Windows Components > File Explorer.
6. Double-click the setting named “Set a default associations configuration file.”
7. Set it to Enabled and enter the full path to the XML file you exported.
8. Apply the policy and reboot the target PCs.

To import associations manually to a specific machine:

cmd

Dism /Online /Import-DefaultAppAssociations:C:\DefaultApps.xml

For scripted per-user deployment, SetUserFTA.exe is a third-party command-line tool designed specifically for this:

cmd

.\SetUserFTA.exe .html ChromeHTML

Verify current associations after running SetUserFTA:

cmd

.\GetUserFTA.exe

Cloud-managed environments can use Microsoft Intune alongside or instead of Group Policy to enforce file associations on enrolled devices without requiring a domain controller.

Warning: Windows 11 enforces Group Policy file association settings more strictly than Windows 10 and typically requires a complete reboot before imported XML associations take effect. Associations applied through Group Policy may not appear during an active user session. Always test on a single device before deploying across the organization.

For other system-level default configurations that IT teams commonly manage alongside file associations, the AxeeTech guide on configuring default printer settings covers the printer default configuration steps that often accompany a new device deployment.

Why Are My Default Apps Resetting? (Fix Guide)

If your default apps revert to Microsoft defaults after you change them, one of five causes is responsible. Work through the table below to identify yours.

Cause	What Happens	Fix
Windows Update reset	Major updates reset file associations back to Microsoft defaults including Edge and Photos	Re-set your defaults in Settings > Apps > Default apps after each major Windows update
App installation hijacking	Chrome, Firefox, Adobe Acrobat, and other apps claim default status silently during install or update	Re-set via Settings; also disable the “Check if default” option in the specific app’s own settings
Managed PC via Group Policy or Intune	IT admin has locked specific file associations	Check Settings > Accounts > Access work or school; contact IT if a work or school account is listed
UserChoice registry permissions locked	The UserChoice registry key has restrictions preventing the user from writing new choices	Follow the registry permissions fix steps below
Corrupted user profile	Association data in the registry becomes corrupt and resets on every login	Run sfc /scannow; create a new user account if sfc does not resolve the issue

Fixing locked UserChoice registry permissions:

1. Press Win+R, type regedit, and press Enter.
2. Navigate to this registry path:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts

3. Expand the subkey for the problematic file extension, for example, .jpg or .html.
4. Right-click UserChoice and select Permissions.
5. Click Advanced in the permissions dialog.
6. Confirm the current user account is listed with Full Control.
7. If Full Control is missing, click Change next to the Owner field, add your user account, and click Apply.
8. Click OK to close all dialogs.
9. Return to Settings > Apps > Default apps and try setting the default again.

Fixing a corrupted user profile:

Run System File Checker in an elevated Command Prompt to repair corrupted system files:

cmd

sfc /scannow

If the system still shows repair activity or enters recovery mode after running sfc, the AxeeTech guide on what to do when your system is repairing itself explains each step of the Windows repair process and when it is safe to intervene.

If sfc /scannow does not resolve the resetting issue, create a new Windows user account and transfer your files to it. For advanced users, deleting all registry keys for the specific extension and then resetting it from scratch resolves stubborn, corrupted associations. The four registry keys to remove for the affected extension are:

HKEY_CLASSES_ROOT\.[extension]
HKEY_CURRENT_USER\Software\Classes\.[extension]
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.[extension]
HKEY_CURRENT_USER\Software\Microsoft\Windows\Roaming\OpenWith\FileExts\.[extension]

Warning: If Settings > Accounts > Access work or school shows a work or school account, your PC is managed. Some file associations are locked by your organization through Group Policy or Microsoft Intune and cannot be changed by the user regardless of what the Settings app shows. This is not a bug. Contact your IT administrator to request a change to the enforced policy.

Windows Update failures sometimes accompany the association reset problem, particularly after major feature updates. The AxeeTech guide on how to fix Windows Update issues easily covers every repair method for stuck, failing, or looping Windows Update processes that often occur at the same time as file association resets.

If file association changes affect Microsoft Teams, Zoom, or communication apps, and you notice microphone access behaving differently afterward, the AxeeTech guide on troubleshooting microphone privacy settings covers the permission checks that communication app installations sometimes disrupt.

Why Doesn’t My App Appear in the Default Apps List?

If the app you want to set as the default does not appear in the picker, one of five causes applies.

1. The app is not installed. Windows only shows installed applications in the default apps picker. Install the app first, then return to Settings > Apps > Default apps to assign it.
2. The app has not registered its file type support with Windows. Some applications do not declare supported file types in their Windows app manifest. Try right-clicking the file, selecting Open with, and clicking “Look for an app in the Microsoft Store” or “More apps” to browse manually. Also try opening the app directly first and using any “Set as default” or “Make default” option in the app’s own settings or preferences menu.
3. Microsoft Store app registration delay. Newly installed apps from the Microsoft Store sometimes take several minutes to register their file type support with Windows. Wait a few minutes and restart the PC if the app still does not appear.
4. The app’s access is restricted by Group Policy on a managed PC. An IT administrator may have restricted which apps can be set as defaults on managed devices. Contact your IT department if the app appears installed but cannot be selected in the picker.
5. The app does not actually support that file format. If an app does not natively open a specific file format, it will not appear in the picker for that extension regardless of installation status. Check the app’s documentation to confirm format support. If the format is not supported, use a file converter or choose a different application.

Running the built-in Windows diagnostics first saves time before manual investigation. The AxeeTech Windows troubleshooter guide walks through each diagnostic tool available in Windows 11 and Windows 10 for identifying software and app conflicts that affect system settings.

Frequently Asked Questions

How do I change which app opens a specific file type in Windows 11?

Open Settings > Apps > Default apps and type the file extension including the dot in the search box, such as .pdf, .jpg, or .mp4. Click the matching result, select your preferred app from the picker, and click Set default. The change applies immediately. You can also right-click any file of that type, select Open with, choose your app, check Always use this app, and click OK for a quicker single-step change.

How do I set VLC as the default for all video files?

Open Settings > Apps > Default apps and type VLC in the search box. Click VLC Media Player in the results. On the VLC page, click Set default at the bottom of the screen. This assigns VLC as the default application for every video and audio format it supports, including .mp4, .avi, .mkv, .mov, .mp3, and .flac, in a single step without needing to set each extension individually.

Why do my default apps keep changing back after a Windows update?

Major Windows updates frequently reset file associations back to Microsoft defaults. Microsoft Edge reasserts as the default browser and the Photos app reasserts as the default image viewer after feature updates. This is a known Windows behavior, not a malfunction. Re-set your preferred defaults in Settings > Apps > Default apps after any major Windows update. If defaults reset on every restart rather than only after updates, check whether the PC is managed by Group Policy or whether an app like Chrome or Adobe Acrobat is reclaiming defaults on startup.

Why is my preferred app not appearing in the default apps list?

The most common reason is that the app is not installed. Windows only shows installed applications in the picker. If the app is installed but still does not appear, it may not have registered its file type support yet. Wait a few minutes after installation and restart the PC. If it still does not appear, the app may not natively support that file format, or your PC may be managed by Group Policy that restricts which apps can be set as defaults.

Can I set different apps for .jpg and .png files in Windows 11?

Yes. Windows 11 treats .jpg and .png as completely separate file types. Open Settings > Apps > Default apps and set .jpg to your preferred viewer, then repeat the process separately for .png. You can assign IrfanView to .jpg files and GIMP to .png files, for example, and both settings remain independent. This level of per-extension granularity is unique to Windows 11 and not available in the simplified category view of Windows 10.

How do I change the default browser in Windows 11?

Open Settings > Apps > Default apps and type your preferred browser name (Chrome, Firefox, Brave, or Opera) in the search box. Click the browser in the results and set each protocol individually: .html, .htm, the http: protocol, and the https: protocol each need to be assigned separately. Windows 11 does not have a single-click category for the web browser unlike Windows 10. Each protocol must be changed one at a time.

Do default app settings apply to all users on the PC?

No. Windows 11 and Windows 10 maintain completely separate default app settings for each user account. Changing defaults in your account does not affect any other user account on the same PC. If you want defaults to apply across all users, Group Policy (on Windows Pro and Enterprise) is the only supported method. Administrators cannot force file associations on other accounts through the Settings GUI.

What is the fastest way to change a default app in Windows 11?

Right-clicking a file and selecting Open with is the fastest method for a single file type change. Select Choose another app, pick your preferred app, check Always use this app to open the file type, and click OK. The entire process takes under 30 seconds. For changing multiple extensions at once, using Settings > Apps > Default apps and clicking the app name followed by Set default is faster than setting each extension one at a time.

How do IT administrators change default apps for all users?

IT administrators on Windows Pro or Enterprise use Group Policy combined with a DISM-exported XML file. Set up a reference PC with the correct associations, run Dism /Online /Export-DefaultAppAssociations to export them to an XML file, then configure a Group Policy Object at Computer Configuration > Administrative Templates > Windows Components > File Explorer and point it to the XML file path. Cloud-managed environments can use Microsoft Intune as an alternative. Third-party tools like SetUserFTA.exe allow scripted per-user deployment for organizations that need more granular control.

What is the Windows 11 default app for PDF files?

The Windows 11 default app for .pdf files is Microsoft Edge. Many users prefer a dedicated PDF reader such as Adobe Acrobat Reader, Foxit PDF Reader, or Sumatra PDF for a better reading experience with tools like annotations, highlights, and form filling. To change it, open Settings > Apps > Default apps, type .pdf in the search box, click the result, and select your preferred PDF application from the picker.
