Run Elevated Powershell prompt from command-line

Sure... works on Windows 7+, too.

Open Powershell first:

Type PowerShell to enter a PowerShell session.

Once in the session:

Type Start-Process PowerShell -Verb RunAs and press Enter.

That will open a new Powershell process as Administrator.

To do it all with only one line from the command prompt, just type:

powershell -Command "Start-Process PowerShell -Verb RunAs"
