Seems like Windows Update tried forcing this out again; I normally handle my updates on my personal laptop manually and caught that it tried to upgrade from 7 to 10 again. Kind of stinks for people that habitually leave their PCs on at all times since this can start installing when the system is idle.
The main reason I haven't bothered upgrading yet is the lack of privacy in the EULA, plus the fact that Windows 8 and up apparently force someone to shut their machine down within fifteen minutes after updates are installed, regardless of whether or not you're in the middle of something.
