I like this story, especially because it brings Powershell to the rescue 😎
The first step is to launch a command prompt running as admininstrator by pressing ‘[Windows key]+X’
Then type “powrshell” and hit enter
Or you can do ‘[Windows key]+Q’, type ‘Powershell’, hit ‘Shift+Enter’ and validate by ‘yes’ the User Account control (UAC) prompt.
The second step requires that you type the following two lines of code and hit Enter (see screenshot below)
Note that you can use Powershell completion with the [TAB] key. For example, start typing ‘Add-App’ and hit [TAB]…, idem for parameters, start typing -Pa and hit [TAB]…
Add-AppxPackage -Path $env:SystemRoot\WinStore\AppxManifest.xml -DisableDevelopmentMode -Register Start-Process "ms-windows-store:"
