Repeating Calculator Windows blocking any other input

Question

Answer 1

This appears to be a "practical joke", rather than accidental or malicious software. First, try starting in Safe Mode.

• In the sign-in screen, hold Shift while clicking the Power button on the lower-right to restart.
• Select Troubleshoot > Advanced options > Startup Settings > Restart.
• After restarting, select the fourth or fifth item to get Safe Mode without or with Network.

If this successfully starts the PC, you can then use an application such as Sysinternals (MS) Autoruns to find out why Calculator runs at bootup and to disable it.

From Safe Mode, you could also temporarily rename the Calculator.exe file, at C:\Program Files\WindowsApps\Microsoft.WindowsCalculator_10.1805.1201.0_x64__8wekyb3d8bbwe, where the the path may vary with your Windows 10 version, or uninstall it:

• In PowerShell, enter Get-AppxPackage *windowscalculator* | Remove-AppxPackage.
