Quick Note: Prerequisites and Initial Checks

Before diving into fixes, make sure of the following:

  • Internet connection: Your device should have a stable internet connection. A weak or intermittent connection can cause purchase errors.
  • Windows Updates: Ensure your Windows 11 is up to date. Updates often fix bugs related to the Microsoft Store.
  • Microsoft Store account: Confirm that you are signed in with the correct Microsoft account that you want to use for purchases.
  • Payment method: Verify that your payment details are valid and up to date in your Microsoft account.

Checking these basics can sometimes resolve the issue immediately.

Step 1: Sign Out and Sign Back Into Microsoft Store

Sometimes, temporary glitches happen with your Microsoft Store account. Signing out and signing back in can refresh your connection.

  1. Open the Microsoft Store app on your Windows 11 device.
  2. Click on your profile icon in the top-right corner.
  3. Select Sign out from the menu.
  4. Close the Store app completely.
  5. Reopen the Microsoft Store and click the profile icon again.
  6. Sign in using your Microsoft account credentials.
  7. Try to buy the app again.

This step ensures your account is properly connected and can fix minor authentication errors causing C101A006.

Step 2: Run the Windows Store Apps Troubleshooter

Windows 11 includes a built-in troubleshooter designed to fix common problems with Microsoft Store apps.

  1. Click the Start button and select Settings (gear icon).
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Store Apps in the list.
  4. Click the Run button next to it.
  5. Follow the on-screen instructions to complete the scan and fix any detected issues.
  6. Once done, restart your PC and try the purchase again.

The troubleshooter automatically detects and repairs problems related to app purchases and installations.

Step 3: Reset the Microsoft Store Cache

The Microsoft Store uses a cache to speed up loading but sometimes it gets corrupted. Resetting it can clear errors.

  1. Press Windows + R keys to open the Run dialog.
  2. Type wsreset.exe and press Enter.
  3. A blank Command Prompt window will open, then the Store will launch automatically after the reset.
  4. Wait a few moments for the process to complete.
  5. Try purchasing the app again.

This step clears the Store cache without deleting your apps or settings.

Step 4: Check Date and Time Settings

Incorrect date and time settings can cause authentication failures with Microsoft services.

  1. Click the Start button and open Settings.
  2. Go to Time & language > Date & time.
  3. Toggle on Set time automatically and Set time zone automatically.
  4. If these are already on, try toggling them off and on again.
  5. Restart your PC and try to buy the app again.

Having the correct time helps Microsoft verify your purchase request securely.

Step 5: Update Payment Information

Sometimes the error is caused by invalid or expired payment methods linked to your Microsoft account.

  1. Open your web browser and go to the Microsoft Payment & billing page.
  2. Sign in with your Microsoft account.
  3. Review your saved payment methods.
  4. Update any expired or incorrect credit card or PayPal details.
  5. Save changes and return to the Microsoft Store.
  6. Try purchasing the app again.

Accurate payment info is required for successful purchases and to avoid errors like C101A006.

Step 6: Re-register Microsoft Store App (Advanced)

If the above steps don’t work, re-registering the Microsoft Store app can fix deeper issues.

  1. Right-click the Start button and select Windows Terminal (Admin) or PowerShell (Admin).
  2. In the terminal window, copy and paste the following command, then press Enter:
PowerShell -ExecutionPolicy Unrestricted -Command "& {$manifest = (Get-AppxPackage Microsoft.WindowsStore).InstallLocation + 'AppxManifest.xml' ; Add-AppxPackage -DisableDevelopmentMode -Register $manifest}"
  1. Wait for the command to finish running.
  2. Close the terminal and restart your PC.
  3. Open Microsoft Store and try the purchase again.

This command reinstalls and re-registers the Store app, which can resolve persistent errors.
