I read an article on Lifehacker last week titled '40 window apps everyone should own'.
One of the recommendations was The PC Decrapifier, which is described;
"When you buy a new laptop and it's loaded with bloatware -- or you're concerned about the amount of seemingly unnecessary programs on the Windows system you've been using for some time -- install The PC Decrapifier. This incredibly useful utility will give you recommendations, based on other users' experiences, about which items you should keep and which items you should trash. You'll sleep easier knowing you didn't accidentally delete a device-critical application."

I haven't used it personally, so can't vouch for it, but it might get rid of unnessecary programs you have that are chewing up data?
