I want to execute a simple "DOS" command BEFORE Windows 7 starts. Of course, I don't need DOS specifically (I know Windows hasn't preloaded "DOS" before the GUI since "Windows ME"). I just want to load/run tiny DOS-like commands before Windows starts. I know in XP, programs like "HiJack This" could tell Windows to delete suspicious files before the OS loads. Can the same thing be done in Win7? My clock is losing time (even after a battery replacement), and I'd like to be able to add 30 seconds (or more) to the clock prior to boot. I think a simple EXE, or even a DOS "Time" command in a ".bat" file during startup would help immensely (I tried adding an "Autoexec.bat", but W7 ignored it.) Is what I'm asking even possible?
