Most users tend to uninstall apps on Windows 10. The simple reason is that these app interfaces make users confused.
To restore or reinstall Windows Store on Windows 10 after removing it with PowerShell, follow the steps below:
1. Run PowerShell as Admin
Open the Start Menu by pressing the Windows key, then enter Powershell in the Search box, right-click WindowsPowerShell and select Run as Administrator.
Or alternatively you can press Ctrl + Shift + Enter to open PowerShell under Admin.
2. Next enter the command below into the PowerShell window:
Get-Appxpackage –Allusers
3. In the output, find the Microsoft.WindowsStore port. Then search for the text PackageFileName.
Next run the PowerShell command as Admin, replacing ****** with the PackageFileName name above to restore the Windows Store:
Add-AppxPackage -register "C:\Program Files\WindowsApps\******\AppxManifest.xml" –DisableDevelopmentMode
For example in the above example is:
Add-AppxPackage -register "C:\Program Files\WindowsApps\Microsoft.WindowsStore_8wekyb3d8bbwe\AppxManifest.xml" -DisableDevelopmentMode
Good luck!
