How to Solve Persistent Microsoft Store App Crashes With Error 0xc000027b on Windows 11?

Why Are Microsoft Store Apps Crashing With Error 0xc000027b on Windows 11?

Microsoft Store apps on Windows 11 sometimes stop working. They close right away. You might see error code 0xc000027b. This code means the app cannot open because something is wrong with permissions or system settings. Here is a simple way to fix it.

Solution 1: Give Apps the Right Permissions

Apps need permission to use parts of your computer. If they don’t have it, they crash. You can fix this.

1. Open File Explorer. Go to C:\Program Files.
2. Right-click the folder. Click Properties. Go to the Security tab.
3. Click Advanced. Click Change permissions.
4. Click Add. Type All Application Packages. Set Type to Allow.
5. Give these permissions: Read & Execute, List folder contents, and Read.
6. Make sure you apply to “This folder, subfolders, and files.”
7. Check the box for “Replace all child object permissions with inheritable permission entries from this object.” Click Apply and OK.
8. Do the same for C:\Windows.
9. For C:\Users, add All Application Packages and give Full Control. Click Apply and OK.

Registry Permissions:

1. Open the Registry Editor (type regedit in the Start menu).
2. For each of these, right-click, pick Permissions, and make sure All Application Packages has Read access:
   HKEY_CLASSES_ROOT
   HKEY_LOCAL_MACHINE\Drivers
   HKEY_LOCAL_MACHINE\HARDWARE
   HKEY_LOCAL_MACHINE\SAM
   HKEY_LOCAL_MACHINE\SOFTWARE
   HKEY_LOCAL_MACHINE\SYSTEM
   HKEY_USERS
3. Click OK. Close the editor.
4. Restart your PC.

Solution 2: Set the Correct Date and Time

Apps need the right time to work. If your clock is wrong, apps may not open.

1. Press Win + R. Type timedate.cpl. Press Enter.
2. Click “Change date and time.” Set it to your local time.
3. Click OK. Restart your PC.

Solution 3: Clear the Microsoft Store Cache

A bad cache can stop apps from working. You can clear it.

1. Press Win + R. Type wsreset.exe. Press Enter.
2. A window will open and close. That’s normal.
3. Restart your PC.

Solution 4: Re-register Microsoft Store Apps

Sometimes apps need to be registered again.

1. Search for PowerShell. Right-click it. Choose “Run as administrator.”
2. Copy and paste this command:

   Get-AppXPackage -AllUsers | Foreach-Object {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml"}

3. Press Enter. Some errors may show. That’s okay.
4. Restart your PC.

Solution 5. Update Windows and Scan for Problems

Old files or broken parts can cause crashes. Updates and scans help.

1. Open Settings. Go to Windows Update. Install updates.
2. Open Command Prompt as administrator.
3. Type sfc /scannow. Press Enter. Let it finish.
4. You can also run: DISM /Online /Cleanup-Image /RestoreHealth
5. Restart your PC.
