Everything in Windows 10 worked perfectly for just 3 or 4 days after upgrading from 8.1. Yesterday I wanted to use the search feature, so I press win+s and get the error "Critical Error: Your Start menu isn't working. We'll try to fix it the next time you sign in."
(I also can't open the settings app since that's also a 'metro' app)
I have tried everything I could find and nothing worked for me.
Things I've tried include:
In powershell:
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
The answer here.
And things like that.
"Did you modify the registry?"
Yes:
Adding Sublime Text 3 to the "Open with" list (It can't be because of this can it?)
Back in Windows 8; Adding a few things to the RMB menu of some files (no trouble at all)
So what can I do to fix these problems?
