For a new process to runas a different (admin) user from powershell

Run a new console window as admin, like so:

Start-Process console.exe -Verb runAs

Or you might prefer

Start-Process powershell -Verb runAs

Or better yet...

Start-Process "$env:ChocolateyInstall\lib\ConsoleZ\tools\console.exe" -Verb runAs

e.g.

Start-Process C:\Users\Leon\Downloads\cmder_mini\vendor\conemu-maximus5\ConEmu64.exe -Verb runAs

Or simply:

Start-Process ConEmu64.exe -Verb runAs

run... run as administrator
