While I find people who say that you can delete it, and your computer will run until you reboot, I find more people who say that either you can't remove it from inside Windows, or you will get a blue screen and a complete crash of the OS during the process.
I found this video that seems to show someone deleting their Windows32 folder but it's probably a fake.
I'm not going to try this myself! LOL
So if your computer is still up and running you probably didn't delete it.
We'd like to know what you find out just for the sake of curiosity.
