Windows 10 Start Button Stopped Working

After a while of testing Windows 10 and everything running smoothly, I finally encountered a bug which was really annoying. The Windows 10 start button stopped working, it just didn’t open anymore. Luckily, I found a solution after reading some forums.

You have to re-register the package used for the start menu and it’s a four-step solution.

1. Press CTRL+ALT+DEL and start “Task Manager”
2. Select “Run new task” in the “File” Menu
3. Type “PowerShell” and select the checkbox “Create this task with administrative privileges”
4. Finally, type or paste the following in the PowerShell: Get-appxpackage -all *shellexperience* -packagetype bundle |% {add-appxpackage -register -disabledevelopmentmode ($_.installlocation + “\appxmetadata\appxbundlemanifest.xml”)}

TIP: CTRL+C and then CRTL+V doesn’t work in PowerShell, instead use CTRL+C to copy and then right-click in the PowerShell to paste!

Hopefully, this will fix any problems with a Windows 10 start button that is not working.

UPDATE: If you also encounter problems with the Cortana search box and/or your metro apps, also run the following code in your PowerShell. This command will re-install all of your metro apps, including Cortana Search.
Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
