I updated, I can say with certainty:

-Until last night, Nvidia drivers were fucking people's shit up hard. MS was forcing a newer, broken version of the driver through Windows Update (which if you're not aware, you cannot disable or tell it 'no'.) Windows Update kept installing these, over and over again, so no amount of driver rollbacks helped. It's solved now, but it definitely doesn't make me feel good about Windows wanting to control all my damned drivers through Windows Update without giving me the option to tell it to fuck off. Borked drivers are not exactly uncommon.

-Everquest works perfectly fine. So does Teamspeak, ramdisk, etc. You shouldn't have much issue with the game or commonly used programs that go along with P99.

I'd be weary of upgrading unless you know you're capable of going back to an older Windows version and/or fixing issues yourself. I personally don't think Windows 10 is ready for release at all (it's honestly kind of a major let down right now), but that's just my opinion.
