How to fix your Windows 10 Start Menu – Critical Error

Hits: 260

I few days ago I started getting “critical error your start menu isn’t working.” reboot now… I saw lots of advice about safe reboot, which only works if the start menu is working.

In the end just logged in regular, I ran Powershell as Administrator, then ran the following command. I went to wash up. Then I rebooted and my start menu came back. It re-installs a bunch of stuff.

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

After lots of red stuff, reboot your computer, after you see the  Powershell prompt.
