How can I run PowerShell from Context menu (holding the shift key) in current folder with admin privileges? Is there a simpler way than type in any code to windows registry?
As LotPings mentions in the comments, you can add a simple shortcut to the Quck Access Toolbar if you are running Windows 10. It's supported by Windows by default.
This image should explain how to set it up.
While this doesn't use shift, you still have a quick way of starting PowerShell in the current directory as admin.
