I've had W10 running on my laptop now for quite a while, and haven't had problems as of yet.
This morning I turned on my laptop, and figured out that the start menu, search, battery, wifi, sound, notification and calendar buttons have stopped working.
The Task View button works perfectly fine, as well as the keyboard type button, as well as clicking all the open windows and pinned items on the taskbar.
Pressing the Windows button on my keyboard equally doesn't do anything. Using Windows is practically impossible without the Start menu.
Creating a new user fixes the problem, although that isn't an option for me for various reasons.
Searching the internet I found a PowerShell command that worked for some:
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
No results for me though.
What to do?
