By the end of this article, you should be able to get your Microsoft Store working smoothly again.

Let’s begin with some quick notes before diving into the fixes.

Quick Note: What to Check Before Troubleshooting

  • Internet Connection: Ensure your PC is connected to a stable internet network. The Microsoft Store needs internet access to download and update apps.
  • Windows Updates: Check if your Windows 11 is up to date. Sometimes, pending updates can cause Store errors.
  • Microsoft Account: Confirm you are signed in to the Microsoft Store with a valid Microsoft account.
  • Storage Space: Make sure your device has enough free space to download or update apps.

Step 1: Run the Microsoft Store Troubleshooter

Windows 11 includes a built-in troubleshooter designed to detect and fix common Microsoft Store issues automatically. This is the easiest and safest first step.

  1. Click the Start button or press the Windows key.
  2. Type Settings and open the Settings app.
  3. Go to System > Troubleshoot > Other troubleshooters.
  4. Find Windows Store Apps in the list and click Run next to it.
  5. Follow the on-screen instructions to complete the troubleshooter.

This tool will scan your system for any problems related to the Microsoft Store and try to fix them automatically.

Step 2: Reset the Microsoft Store Cache

Sometimes, corrupted cache files cause errors in the Store. Resetting the cache can clear out problematic data without affecting your installed apps.

  1. Press Windows + R to open the Run dialog box.
  2. Type wsreset.exe and press Enter.
  3. A blank Command Prompt window will open, and after about 10 seconds, the Microsoft Store will launch automatically.

This process clears the Store’s cache and may resolve the 0x803fb005 error by refreshing the Store’s internal files.

Step 3: Check Date and Time Settings

Incorrect date and time settings can cause Microsoft Store errors because the system certificates and servers rely on accurate timing.

  1. Open Settings from the Start menu.
  2. Go to Time & Language > Date & Time.
  3. Make sure Set time automatically and Set time zone automatically are turned on.
  4. If they are already on, toggle them off and on again to refresh the settings.

After adjusting, try using the Microsoft Store again.

Step 4: Sign Out and Sign Back Into Microsoft Store

Sometimes, authentication problems with your Microsoft account can trigger Store errors. Signing out and back in can refresh your credentials.

  1. Open the Microsoft Store app.
  2. Click on your profile icon in the top-right corner.
  3. Select Sign out.
  4. Close the Store app completely.
  5. Open Microsoft Store again and sign back in using your Microsoft account.

This process helps re-establish a proper connection between your account and the Store servers.

Step 5: Run System File Checker (SFC) Scan

Corrupted system files can affect the Microsoft Store’s functioning. The System File Checker tool scans and repairs these files.

  1. Press Windows + S, type Command Prompt, right-click it, and choose Run as administrator.
  2. In the Command Prompt window, type the following command and press Enter:
sfc /scannow

The scan may take some time. When finished, it will report if any corrupt files were repaired. Restart your computer after the scan.

Step 6: Reinstall Microsoft Store

If none of the above steps work, reinstalling the Microsoft Store app can fix deeper software issues.

  1. Open PowerShell as administrator: Press Windows + S, type PowerShell, right-click it, and select Run as administrator.
  2. Copy and paste the following command, then press Enter:
Get-AppxPackage -allusers *WindowsStore* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)AppXManifest.xml"}

This command reinstalls and re-registers the Microsoft Store app.

Alternative Fix: Check Windows Update Services

Sometimes, the Microsoft Store error can be linked to Windows Update services not running properly.

  1. Press Windows + R, type services.msc, and press Enter.
  2. Scroll down and find Windows Update.
  3. Right-click it and select Restart.
  4. Also, ensure the Startup Type is set to Automatic.
  5. Restart your PC and check the Microsoft Store again.
