"... it's clear that at least 100 million PCs are still running Windows 7, and that number could be significantly higher..."Gee, ya think?
I would still be running XP if it wasn’t for Bill Gates and Co., locking me out. I had to swap an audio card and the XP box wanted a non-available authorization code to use. Gave me 3 days to rectify, which I couldn’t so I was locked out. I consider this a breach of trust by microsoft. How many users got shafted by Gates piracy hurdles that were blocked as support for XP stopped?
Needless to say, no more windows for me. Linux with wine for running windows apps.
