You guys think you are so funny.
Oh wait, you are.
The option is meant for data drives, not OS drives as it can ruin Win7 by compressing the boot files.
There is a fix for it here: BootMGR Compressed Message at Boot Fix - Vista Forums
DO NOT compress your C drive. I did this a few years ago when running WinXP and the resulted in having to do a fresh install because system would not boot up!
You have been warned!
