What os are you using?

I loved Windows XP when it came out, and it was fantastic, however it is very old so I only use it on occasion these days, and I hardly see it anymore. ThenI used Windows 7 for several years and it was really great too, but I have also moved on from that.

These days I primarily use Windows 10 Pro, although I disable Cortana and some of the other junk they added to it. And I usually use Start10 since I am not a huge fan of the Start Menu changes. However on my Windows tablet I still use the new start menu since it works better with touchscreen devices.
Windows 10 is to me, a natural progression from Windows 7.

I had Windows 8 and 8.1 and it was alright, I just didn't like the Start Screen very much so I used Start8. Although I think it would have been really good if I had a Windows tablet at the time.

At any rate, I use a few different Linux distros on occasion, and Windows 7 at work. I also use Windows Server 2012 regularly at work, although through Remote Desktop to a server at our corporate office.
