Windows 7 is pretty close to EOL now. Companies might not have migrated off it yet, but they're going to have basically no choice in short order. I doubt Microsoft are going to suddenly change how they handle updating the OS in the next year or so -- at the end of the day, there's no real competition for the business desktop -- so I expect we all have some fun and games to look forward to.
For what it's worth, I'm a home user still on Windows 7 plus a bit of Ubuntu. When Windows 7 finally hits EOL, that's it for Windows for me. After having had the displeasure of using family members' MacOS or newer Windows devices a few times, I'm out.
