Start menu not working

So I booted up my pc and and it the start menu was not working I was a bit shocked however there is a fix.

1. On the bottom bar right click >Task Manager
2. On the task manager click on File then >Run New Task
3. Type PowerShell and make sure Create this task with Administrative Privileges is checked
4. Click Ok
5. In windows power shell make sure you see the following text "Windows PowerShell
Copyright (C) 2015 Microsoft Corporation. All rights reserved.PS C:\WINDOWS\system32>
6. Copy and paste this and it should take few seconds to paste.
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}

Lets hope for no further issues. this started after I used Wisecare 365 to clean up my pc I think that may have had effect.
