Settings will not open in Windows 10

Hi,

Thanks for reply.

If you are unable to open Settings through Start Menu, I suggest you to follow the suggestions below and check if that works for you:

1. Open the Task manager.  Here’s a tip:  Press CTRL+Shift+ESC.
2. Click File > Run New Task.
3. Make sure you have a check mark beside “Create this task with administrative privileges”
4. Type CMD.
5. Type the following 4 commands at the CMD prompt: dism /online /cleanup-image /restorehealth
   sfc /scannow
   powershell
   Get-AppXPackage -AllUsers |Where-Object {$_.InstallLocation -like "*SystemApps*"} | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
6. Close the CMD window

Check to see if the issue is resolved. If not, restart the PC.

I suggest you to refer to the article below and refer to the section ‘Can I uninstall Windows 10 if I do not like it or something goes wrong’ and check if it helps to roll back to 8.1:
