which version of windows 7 do you use?

[Baggervance]

Use 8.1 on 2 of my machines but still using 7 ultimate on the other one

[isolect]

I use professional and never had a problem.

I use enterprise, it seems to have everything that ultimate offers

[lynxx]

A not official one... (for that one program wine can't run)

[Quaternion]

Believe it or not I use the Home version. It's the cheapest version and there are work-arounds / patches for most Ultimate features such as Remote Desktop.

With a legal copy of M$ Windows I also get the weekly security patches (updates).
