*sigh* Well, I suppose then that the thread remains derailed...yay, me!
In any case...
@comptech08 - why would doing a clean install be a waste of money? A waste of time, perhaps (as you've all pointed out), but...of money? And, though my parents are very free with what little money they have, I am a 41-year-old ex-military guy who has a little money to spare and a great love for things computer-related and likes to (when I can afford it) have the latest and greatest.
Part of the reason why I do clean installs so often is because I've always been (and the military only made it worse!) obsessive-compulsive about cleanliness/organization, and a clean/well-organized, sparkly OS is next to godliness, yah?
As for Pr0n, well I could deny until I die, but what would that matter? In other words, why would that necessitate clean installs? Likewise "hax" or warez...if I knew anything about anything, why would the possession of warez on my rig make clean installs necessary? And what do you mean by "hax", exactly?
An aside - why, if I had anything besides some no-name, piece-of-shit hard drive, would I have to upgrade *it* every time I do a clean install? O_o?
As for a CD key - well, mate, I'm currently running the latest build of Windows 7, complete with my valid CD key from Microsoft, so I'm good until June of next year, n'cest pas?
