Gf's Mum's dell PC has been f**ked over by a virus to the point that msconfig and windows help can't find their files. I've read that the virus has actually changed altered filenames and such to try and stop you from removing it. Anyway, rather than spending days trawling through means of getting it all back to normal, i think a good reformat would be just as good. We have no xp cd's but we do have the serial code stuff attached to the side of the computer, i was always under the impression that XP cd's are worthless and it's the serial code you pay for, so is there any way i can download and legitimately burn windows xp to some cds, or buy just the cds without any license? Would that work?
