DING DING DING!! Winner!
Exactly correct. Large enterprises such as the one I work in (20,000+ desktops) aren't going to be moving off Windows 7 anytime soon. We were lucky to actually upgrade to Windows 7 / 64 Bit after our dumb director of Engineering said "what user needs more than 4gb to do their job?"
Thank God and greyhound he's gone .......
OTOH, I just updated to the latest Windows 10 Bits (10158) and so far am liking what I see. It's downright ZIPPY!
Large corporations I'm familiar with generally keep their operating systems upgraded before, or at least shortly after EOL. For W7, that's January 2015. Security updates will still be provided to 2020.
