|Thanks for the reply.|
I upgraded with the kit they sent out to applicable laptops that were bought within the timeframe they made. I did not clean install, just upgraded.
The thing is, I have had Windows 7 on this laptop for quite some time now. and I haven't seen anything like this in all the time I had it, as well I haven't deleted anything recently.
I know that Vista was a real pig on that restore stuff, and I think that it was taking up a good 50gb onwards into Windows 7 for me (it think it decreased a good amount though) which makes me think that could be the only thing possible with such a gross gain of space such as 40GB.
The thing I left out is that I had a virus, which I'm guessing Kaspersky caught because it is showing no active threats, but I spybot S&D's my computer afterwards as well, and it just gave some cookies that I deleted.
Could this virus have possibly done this?
And where is disk management?
