Dood, I've got Vista.
And It sucks ass. Hard.
I had a separate drive for my recovery files, little something that I made to make sure that if my computer gets blown to bits due to my frquent torrent downloading, I would have something to fall-back on. I put every security protection on there, Non-rewritable, on system alert, shiz like that.
Then, I had to format a blank disc I had just bought, but Instead of formatting the disc, It formats Everything other than C:/, which means my recovery files are gone. Now I can't make another one since 'Access is Denied' (I HAVE FULL CONTROL WTF?).
Also, The amount of space left in My C:/ drive seems to just dwindle away slowly, even though I haven't downloaded/added/installed anything for the past coupla days.
