I have vague memories from the Windows 3.1 era of writing a batch file that would replace AUTOEXEC.BAT and CONFIG.SYS with stripped-down versions (after creating backup copies). This would save memory and allow some games to run that otherwise wouldn't. I'd run the batch file, then reboot and play the game. When I was done, I'd run another batch file to rename the backup copies onto the original files, then reboot again and Windows would start. Good times.
