When you right-click a PowerShell script in File Explorer, you typically find a context menu entry called “Run with PowerShell” which lets you easily execute the PowerShell script.

However, on some systems, the “Run with PowerShell” command is missing. It turns out the command is hidden once you define a non-default “OpenWith” command. To repair this, all you need to do is delete this registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ps1\UserChoice

Deleting this key manually in regedit.exe is trivial, and once the key is removed, the “Run with PowerShell” context menu is visible again.

It turns out deleting the registry key with PowerShell is not trivial, though. All of these commands fail with the same exception, complaining that some subkey cannot be deleted:

 
PS C:\> Remove-Item HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ps1\UserChoice

PS C:\> Remove-Item Registry::HKEY:CURRENT_USER:\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ps1\UserChoice

PS C:\> Remove-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ps1\UserChoice'

PS C:\> Remove-Item HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\'.ps1'\UserChoice

PS C:\> Remove-Item HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ps1\UserChoice -Recurse -Force
