How to run PowerShell with admin privileges from current folder?

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.

I have had the same problem recently. Answer unfortunately wasn't obvious and easy to find. There are some scripts on the internet but has worked form me. Below i am presenting to You script which You can paste into any file with reg extension and run. After that You will be able to run powershell with admin privileges from current open folder (You have to hold shift and then right click on empty space in folder.

Code:

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\Directory\Background\shell\PowerShellAsAdmin]
@="Open PowerShell window here as administrator"
"Extended"=""
"HasLUAShield"=""
"Icon"="powershell.exe"

[HKEY_CLASSES_ROOT\Directory\Background\shell\PowerShellAsAdmin\command]
@="C:\\Windows\\system32\\WindowsPowerShell\\v1.0\\powershell.exe -windowstyle hidden -Command \"Start-Process powershell  -ArgumentList '-NoExit', '-Command cd %V' -Verb runAs\""

Dominik's registry solution works well, but there is a problem when the folder path contains spaces. In the command, you have to add (escaped, i.e. double) apostrophes around the path.

C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe -windowstyle hidden -Command "Start-Process powershell -ArgumentList '-NoExit', '-Command cd ''%V''' -Verb runAs"
