Create batch file to run with elevated permissions to activate windows 10

I had a task of automating Windows 10 upgrades from Windows 7, and one key thing I needed to do was allow for UAC to exist, AND be able to run batch scripts, or powershell scripts as Administrator. Also known as elevated permissions.

I created a bat file with these contents:

set mydir=%~dp0
Powershell -Command “& { Start-Process \”%mydir%2.bat\” -verb RunAs}”

I then created a second bat file with 2.bat, and placed it in the same directory with this:

cscript C:\Windows\System32\slmgr.vbs -ipk xxxx-xxxx-xxxx-xxxx-xxxx
cscript C:\Windows\System32\slmgr.vbs /ato

This only brings up ONE prompt for the user, the UAC prompt to hit yes. No password required, and not VBS pop ups showing status, thanks to cscript.
