Windows Running

@echo off
:: The MEM /M command tells if a program is running and
:: what memory it is using. Based on my observations, WIN
:: runs (and doesn’t stop) after Windows starts. But VMM32,
:: the virtual memory manager, only runs while the Windows
:: GUI is active. Using these observations, a DOS batch file
:: can tell what kind of a world it is running in.
