Windows 8.1 Don't want to deal with any of that Windows 10 bullcrap, though I may be forced to upgrade as Microsoft is going to force skylake users to do so.
windows 7 ultimate 64bit have serve me well over the years so i'm gonna stick with it until it become obsolete... still on the fence about windows 10 upgrade thingy (IMG:[invalid] style_emoticons/default/dry.gif)
