How to Fix Event ID 1001 StoreAgentScanForUpdatesFailure0

Follow these methods in order, from the easiest to more advanced fixes.

1. Restart and Basic Checks

• Reboot your system and check again.
• Ensure you have a stable internet connection.
• Disable VPN or proxy temporarily.

Sometimes the error is a one-time glitch that disappears after a restart.

2. Run Windows Troubleshooters

Windows has built-in tools for common update and Store problems:

1. Go to Settings > System > Troubleshoot > Other troubleshooters
2. Run Windows Update Troubleshooter
3. Run Microsoft Store Apps Troubleshooter

If these tools repair the issue, you won’t need to proceed further.

3. Reset the Microsoft Store Cache

Corrupted cache files can block updates. To reset:

1. Press Win + R, type wsreset.exe, and press Enter.
2. A command window will open and close automatically.
3. The Microsoft Store will relaunch with a fresh cache.

4. Check and Restart Update Services

Critical services must be active for updates to work:

1. Press Win + R, type services.msc, and press Enter.
2. Locate and ensure these are Running and set to Automatic:
   • Windows Update
   • Background Intelligent Transfer Service (BITS)
   • Cryptographic Services

If any are stopped, right-click → Start.

5. Run System File and Health Scans

Corrupt system files are a major cause of this error. To repair them:

• Open Command Prompt (Admin)
• Run the following commands one by one:

DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow

• DISM repairs the Windows image.
• SFC scans and fixes corrupted system files.

6. Scan for Malware

Malware or security conflicts may interfere with update scans.

1. Open Windows Security from the system tray.
2. Go to Virus & threat protection > Scan options
3. Choose Full scan > Scan now

If threats are detected, quarantine them. You may also try a reputable third-party antivirus.

7. Free Up Resources and Memory

• Close background apps:
  • Open Task Manager (Ctrl + Shift + Esc) → End unneeded apps and background processes.
• Disable startup apps:
  • In Task Manager > Startup tab, disable unnecessary apps.
• Free disk space:
  • Run Disk Cleanup (cleanmgr) and delete unnecessary files.

If your PC is low on memory:

1. Search for Adjust the appearance and performance of Windows
2. Go to Advanced > Virtual memory > Change
3. Increase the paging file size (custom size).

8. Re-register Microsoft Store

If the Store itself is broken, re-register it:

1. Open PowerShell (Admin)
2. Run:

Get-AppxPackage -allusers *WindowsStore* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml"}

This reinstalls and refreshes the Microsoft Store app.

9. Reinstall Problematic Apps

If the error is linked to a specific app:

1. Press Win + R, type appwiz.cpl, and press Enter.
2. Select the app > Uninstall
3. Restart and reinstall the latest version from the official source.

10. Last Resort: System Restore or Reset

If none of the above works:

• Use System Restore to roll back to a working state.
• Or perform a Windows Reset (keeping files) to reinstall the system.
