From inside a batch file, I would like to test whether I\'m running with Administrator/elevated privileges.
The username doesn\'t change when \"Run as Administrator\
I like Rushyo's suggestion of using AT, but this is another option:
whoami /groups | findstr /b BUILTIN\Administrators | findstr /c:"Enabled group" && goto :isadministrator
This approach would also allow you to distinguish between a non-administrator and a non-elevated administrator if you wanted to. Non-elevated administrators still have BUILTIN\Administrators in the group list but it is not enabled.
However, this will not work on some non-English language systems. Instead, try
whoami /groups | findstr /c:" S-1-5-32-544 " | findstr /c:" Enabled group" && goto :isadministrator
(This should work on Windows 7 but I'm not sure about earlier versions.)
