How much is a Windows license these days? It seems to me it would be cheaper, or at least equal in price, to install a clean copy of Windows rather than go to the trouble of "decrapifying" your computer. I realize a lot of Windows users don't have this ability, but I don't see why MS couldn't do it themselves and save time. Also, what's the legal status of using a clean install disk with my crapified computer's registration key? If I want to reinstall Windows, am I obliged to reinstall the crapware too? If I could reinstall a clean OS for free, $99 is a racket. Someone with a Windows disk could make a pretty penny undercutting MS here. Of course, one of the reasons I use Linux is because dealing with Windows like this is a legal minefield.
