Windows 10 is absolutely fine for me.
However, make sure your anti-virus software isn't going to block everything. For example, I once had the AVG Protection anti-virus software, and that completely blocked me from playing IT servers altogether. It's NOT fun!
My main recommendation is Avast, they scan the programs you run more more effectively and don't block it altogether without searching through it first; the only time the suspicions will rise is if they ever find a problem while scanning it. IT servers and FH won't have any problems to your computer, and therefore will be no need to turn off your Firewall or anything.
Basically, just make sure everything works- and if not, try checking your firewall or your anti-virus software. =P
