Am I running as Administrator in a Windows batch file

Am I running as Administrator in a Windows batch file

This is a great way to test:

whoami /groups | findstr /b BUILTIN\Administrators | findstr /c:"Enabled group" && GOTO RunningAsAdmin
ECHO This must be run as AdministratorGOTO NotRunningAsAdmin
:RunningAsAdmin

Windows Command line redirect stdout and stderr to the same file

I keep forgetting how to do this, so:
Windows Command line redirect stdout and stderr to the same file like this:

someprog.exe > log.txt 2>&1

Don't let environment values persist after a batch file runs

To prevent environment variables declared in a batch from being persisted after the batch file is run, use this command before setting them:

setlocal
