What OS are you using?

I'm with Windows 7 and will always be. I have the hardware resources to run Windows 10 or the latest Ubuntu but neither of both performed well. Windows 10 was stuttering and thinking way too much as if I've run it on a Pentium I machine, not on a quad core system with 8GB RAM and 2GB video card. All Linuxes after Ubuntu 10.10 run like Windows 10 and some won't even start the live environment. But even if they did, I would still prefer Windows cuz it's more receptive to drivers, while Linux accepts drivers only until you reboot the system. After the reboot all drivers are gone as if they never existed.
Windows 8.1 is not bad but it has some kernel issues which I suspect will never be fixed. Works a few days then suddenly the scheme starts changing on its own. I reported that to MS but they replied they didn't provide support for fake keys and I told them I'll never pay €750 for 3.6GB. GTA V fits on several DVDs and it's 15 times cheaper than that, FFS!
So I'm with Windows 7 since 2007 (updated 2015) and I love it. It's the least resource demanding operating system and works the way Windows 8 and 10 should work but they don't.
But my favorite feature is how Windows 7 manages the usage of RAM - like no other! Whatever amount of RAM is taken, the moment you close the process taking it, that taken amount of RAM is immediately released as if it was never taken. That's a feature no other Windows OS has (with other Windows OS you have to reboot the system for the taken RAM to be released) and it's one of the things that makes Windows 7 so awesome.
