Microsoft Store is blocked error occurs when Windows prevents access to the Microsoft Store app, displaying the message “Microsoft Store is blocked. Check with your IT or system administrator.”

This situation typically happens on organization-managed devices, where administrators disable the Store through group policies or mobile device management. The error is also observed on home PCs if the same restrictions are applied, either by design through registry edits or inadvertently through third-party tools.

When this happens, you can no longer browse, download, or install apps from the Store, eliminating productivity and access to the software needed. Common culprits include system configuration locking the computer down for single-app (kiosk) operation, corporate or school account restrictions, or even Windows S Mode operation, which is meant to allow only Store apps but sometimes configured to ban the Store as well.

Potential solutions to resolve the Microsoft Store is blocked error include:

• Reviewing and modifying Group Policy settings related to Store access.
• Checking and correcting relevant registry keys that disable the Store.
• Exiting Assigned Access or kiosk mode configurations.
• Switching out of Windows S Mode or adjusting its settings.
• Ensuring user accounts have appropriate permissions and aren’t governed by restrictive management policies.
• Re-registering or repairing the Microsoft Store app to clear misconfigurations.
• Running the Windows Store Apps troubleshooter to detect and fix common Store issues.

Fix 1. Modify group policy settings

Changing the policy that disables the Store can immediately restore access if your Windows edition includes the Local Group Policy Editor.

• Type Group Policy in Windows search and hit Enter.
• Navigate to the following location:
  Computer Configuration > Administrative Templates > Windows Components > Store
• Double-click Turn off the Store application and set it to Disabled or Not Configured.
• Click Apply and OK, then close the editor and launch the Store.

Fix 2. Correct registry keys

If group policy isn’t available, adjusting the registry can remove the block on the Store.

• Type regedit in Windows search and press Enter.
• User Account Control windows should show up – click Yes when prompted.
• Go to the following location (copy into the address bar at the top): HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\WindowsStore
• If a DWORD named RemoveWindowsStore exists, double-click it and set its value to 0.
• Repeat in HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\WindowsStore.
• Close Registry Editor and open the Microsoft Store.

Fix 3. Exit kiosk or assigned access mode

Devices in kiosk mode intentionally block the Store; exiting this mode will restore normal functionality.

• Right-click on Start and select Settings.
• Go to Accounts > Other users.
• Select the kiosk account and click Remove.
• Follow the prompts to exit Assigned Access and sign back in normally.
• Check if the Store is unblocked.

Fix 4. Switch out of Windows S Mode

Windows S Mode can block app installations, including the Store itself if misconfigured.

• Right-click on Start and pick Settings.
• Navigate to the Update & Security section.
• Click on Activation on the left-hand menu.
• Look for the Switch to Windows 10/11 Home or Switch to Windows 10/11 Pro section.
• Select the Go to the Store link and click Get.
• Follow the on-screen instructions to complete the switch out of S mode.

Fix 5. Enable Microsoft Store Install Service

If the service that handles Store operations is disabled, the app cannot run.

• Type Services in Windows search and press Enter.
• In the Services window, scroll down to locate Microsoft Store Install Service.
• If the service is already running, right-click it and select Restart.
• If it is not running, double-click it to open Properties.
• Under Startup type, click on the drop-down menu and pick Automatic.
• Click Start, Apply, and OK.

Fix 6. Sign in with local user account

Standard accounts may inherit restrictions; granting administrative rights can eliminate the block.

• Right-click on Start and select Settings.
• Go to Accounts > Your info.
• If your account is Standard, click Sign in with a local account instead and follow prompts to create an administrator account.
• Sign in to the new administrator account and open the Store.

Fix 7. Reset or repair Microsoft Store app

Resetting restores default settings and clears any misconfigurations causing the block.

• Right-click on Start and select Apps & Features/Installed apps.
• Scroll down to find Microsoft Store and click Advanced options or go to Settings > System > System Components > Advanced options.
• Scroll down again and click Terminate and Repair.
• If that does not work, try using Reset.

Fix 8. Re-register the Microsoft Store app

Re-registering reinstalls the Store’s core components without affecting your data.

• Type PowerShell in Windows search.
• Right-click on the result and select Run as administrator.
• When UAC shows up, click Yes.
• Use the following command and press Enter:
  Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
• When done, restart your computer.
