Which version of Windows you are using now?

Windows 7 on my main machine, but have experience with 8 and 10 also. For my personal taste I prefer windows 7. Windows O/S Versions 8 through 10 are more geared toward pads and tablets which is fine for those applications, but when it comes to coding or using a desktop Windows 7 wins hands down. Not to mention that with Windows 10 Microsoft has started gathering user data on virtually every user using that OS.
