Run the Windows Store Apps Troubleshooter and Reset Cache

This is the most common and effective method to resolve built-in Microsoft Store glitches preventing application downloads.

The Windows operating system includes a dedicated troubleshooter that automatically detects and resolves issues with Microsoft Store applications. Paired with a store cache reset, this resolves most download failures.

1
Open Windows Settings

Click the Start menu and select the gear icon to open Settings, then navigate to 'Update & Security'.

2
Run the Troubleshooter

Select 'Troubleshoot' from the left pane, click on 'Additional troubleshooters', scroll down to find 'Windows Store Apps', and click 'Run the troubleshooter'.

3
Clear Microsoft Store Cache

Press the Windows Key + R to open the Run dialog box. Type 'wsreset.exe' and press Enter. A blank Command Prompt window will appear and close automatically once the cache is cleared.

Run the Windows Store Apps Troubleshooter and Reset Cache
Automatic Restart: The Microsoft Store will automatically launch once the cache reset process is successfully completed.

Frequently Asked Questions

Why is my Microsoft 365 download stuck on pending in the Microsoft Store?

A pending status usually indicates that the Microsoft Store is waiting on background Windows updates to finish, or there is an issue with the local store cache. Installing pending Windows updates and clearing the cache (using wsreset.exe) often resolves this.

Can I install Microsoft 365 on Windows without using the Microsoft Store?

Yes. You can bypass the Microsoft Store entirely by logging into your Microsoft account online, navigating to 'Services & subscriptions', and downloading the desktop installation file directly.

What PowerShell command fixes Microsoft Store installation errors?

You can re-register the Microsoft Store by opening PowerShell as an Administrator and running the command: Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}.
