I think Windows rot stopped being a thing since XP. Windows 7 and Windows 8 installations rarely slow down over time, unless you're installing toobars and adware.
I have a Windows 7 that suffered Windows rot over the year I used it. I finally gave up and went back to the Ubuntu share (despite the Toshiba brightness bug) when Windows refused to suspend properly.
With Windows, it might work somewhat or with great annoyance. Or it might be lovely! Until Windows rot sets in.
