If you are a Windows Insider you may have noticed that on the latest Windows 10 fast preview build number 17112 that your Windows Store icon is completely missing. Not only is the icon missing, but the entire app is broken for many users prompting Microsoft to post a special fix.
If you are impacted, follow these steps to bring the Microsoft App Store back:
- Right-click on the Start Button and select Windows Powershell (Admin). Make sure to select the "Admin" listing, otherwise, the next steps will fail.
- Copy and paste the following command into the PowerShell window and hit Enter.
Get-AppXPackage *WindowsStore* -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”} - After the command runs you may see an error, that is expected. Just reboot your PC and the store should be fixed. However, in my case, a reboot was not needed.
