How to detect if CMD is running as Administrator/has elevated privileges?

Question

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\

Answer 1

the solution:

at >nul
if %ErrorLevel% equ 0 ( echo Administrator ) else ( echo NOT Administrator )

does not work under Windows 10

for all versions of Windows can be do so:

openfiles >nul 2>&1
if %ErrorLevel% equ 0 ( echo Administrator ) else ( echo NOT Administrator )
