Solutions
Solution 1: Reset Microsoft Store Cache
- 1Quick reset: Win+R → type wsreset.exe → Enter
- 2Wait for Store to open (may take a minute)
- 3Try downloading the app again
- 4If that doesn't work — full reset:
- 5Settings → Apps → Installed apps → Microsoft Store → Advanced options
- 6Click "Reset" (this clears all Store data)
- 7Sign back into Microsoft Store and retry
Solution 2: Re-Register Store Apps
- 1PowerShell as Admin:
- 2Get-AppxPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml" -ErrorAction SilentlyContinue}
- 3Wait for completion (may take several minutes)
- 4This re-registers all Store app packages
- 5For a specific app: uninstall it first, then reinstall from Store
- 6PowerShell: Get-AppxPackage *appname* | Remove-AppxPackage
- 7Then reinstall from Microsoft Store
Solution 3: Fix Download Infrastructure
- 1Ensure you have enough disk space (at least 5GB free on C:)
- 2Check Windows Update service: services.msc → "Windows Update" should be Running
- 3Reset Windows Update components (Store uses same infrastructure):
- 4CMD as Admin: net stop wuauserv && net start wuauserv
- 5Disable antivirus temporarily — some block Store package verification
- 6Check date/time: Settings → Time & language → ensure correct date/time
- 7Wrong date/time causes certificate validation failures with Store
