When I would use a Microsoft OS, I would choose Windows 7 64 Bit as Professional Version. Stable and Fast.
Now I prefer since 9 month LInux (Mint - based on Ubuntu and Kali)

Windows 7 SP3 64 bits.

Windows 7, it's pretty easy to rice and make it look aesthetically pleasing and it can run games fine. The ones prior either looked ugly or has serious exploits that're never patched, and Windows 10 looks ugly with a lot of intrusive spyware that you can't disable... despite Microsoft claiming you can. Open up Wireshark and check the packet outflow on Win10 if you don't believe me.

windows 10. imo much better than 7. better looking, faster, more polished, driver ready for almost anything. really love it.

windows XP of course it's the one i've used the longest

Windows XP

Windows XP, 7 and 10.
I have a feeling windows 10 might even be the best one yet, based on what I've heard and read about it, as I haven't got to try it myself (yet ).

Poor vista, no votes for you... I wonder why

I think I've used XP the longest time, it was all right.

Win XP, practical and simple, maybe just security too bad for now
