My Admin Login Can Use My Windows 10 Start Menu But As A User Start Menu Doesn't Work.

Hi

One approach that could work for this is to use Powershell, so if you have the search box type powershell and right click and run as admin it, then once open paste this line below in and hit enter, let it run and if you see red text dont worry its normal

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

Once run reboot and test the Start menu, you may have to populate the Start menu with the common used apps if you added any, but it should leave the choices you made intact.
