I have tried:
Get-ChildItem 'HKCU:\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\Children' | foreach {Remove-Item $_.pspath -Recurse}
Which deletes all of the subtrees of Children and makes no difference
1.Press Windows key + X and open the Command Prompt (Admin)
2.In the Command Prompt, type in Powershell and press Enter
3.Paste the following line into the PowerShell window and press Enter ◦Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}
4.Wait until it’s completed, and C:\Users\yourusername> will appear on the screen when the process is completed
5.Reboot your computer and try to open Edge again
Which makes no difference.
