What do I do if my Windows 10 Start Menu doesn't work?

Windows 10 has a known and seemingly both random and popular glitch where the Start Menu does not open, whether you use the keyboard key or click on the icon. Other keyboard shortcuts that involve the Windows key, however, continue to work. To fix this issue, there are a few things you can do: reinstall/refresh Windows (but who has the time or wants to do that?), restart (but doesn't always work), create a new account, or reinstall the Windows 10 Modern/Metro apps (seems to work so far so we'll walk you through that).

1. Open Powershell (as an admin)
   If you can't open Powershell, open the command prompt and type in "powershell"
2. Type in (or copy/paste)
   Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
   
3. Ignore any errors or red text
   
   It might say that some app failed because the version installed is newer; it might say something else.
4. Restart when complete
   It completes when you see PS C:\Windows\system32\> _
