Version 6.1 Build 7601 with Service Pack 1 (aka Windows 7).
I have considered updating to Version 6.2 (aka Windows 8) or more likely Version 6.3 (aka Window 8.1), but without a touchscreen, it just doesn't seem worthwhile.
You can figure out which version of Windows you are running by running the "winver" application that is a part of Windows.
