8.1 reminds me of Vista and Millenium, I'm afraid it so choose from the 7 and 10 ...7 is too old, 10 is too new.
8.1@regeszter Your choice?
I do not is suitable there are already 7, can be upgraded to 10 ...
I also have a license, so I think the update or not.i have upgraded quasi all my PC to win10 ( valid licence for Win7 Pro (15€/lic) )
I also have an older graphics card, HD2400, and HD3870For now; i don't have big issue on Win10 except the missing feature on old graphic card (ATI HD4600, i wait for the next gen with support hdmi 2.0 built in )
