Store files corrupted

This does not necessarily mean the Store files are corrupted. The free-space and disk checks rule out two common causes, but the exact Store error code is more useful than the general Windows Error Reporting entries.

Start by pressing Win + R, running wsreset.exe, and waiting for Microsoft Store to reopen. Then go to Settings > Apps > Installed apps > Microsoft Store > Advanced options, select Repair, and test one affected app. If that does not help, select Reset and sign back into the Store.

Open services.msc and make sure Windows Update, Background Intelligent Transfer Service, and Microsoft Store Install Service are not disabled. Restart the PC, install pending Windows updates, then open Store > Library > Get updates.

If several apps still fail, open an Administrator Terminal and run:

DISM /Online /Cleanup-Image /RestoreHealth sfc /scannow

Restart after both commands finish. Before resetting any affected app individually, back up its local data because Advanced options > Reset can erase that app’s settings and stored data.

If the problem continues, test Microsoft Store from a new Windows user account. If it works there, the problem is limited to the original user profile; if it fails there too, report the exact Store error code and the entries under AppXDeployment-Server > Operational. The SecurityCenter entries may only be recording AVG’s security-provider status and are not necessarily the cause.
