Just upgraded to windows10
I did too, on one of my Win7 drives (still have Win7 on another ssd)... made me laugh because I've been running an old i7 920 @4Ghz overclock for years on Win7, on Win10 video playback is double speed in VLC player! lol - the only thing that cured it was to knock the clock back to standard!
RE: Emoticons, never had an issue, but then again I don't really use them that much. Running FF 42/3 atm.
