Good for Parallels
on 9 August 2015
Bought from Amazon itself, this is a genuine OEM version. It installed & activated without any problem in my Parallels Desktop for Mac, then spent a long time updating.
I wanted to use the "GWX" tool to reserve Windows 10 for free & to do that I had to edit the registry - it was simple, I just googled & followed advice from a web page. Parallels have probably fixed this since I tried - I see they now have advice on their forum on the best way to update to 10. I haven't rushed to update to 10 but it's nice to have the option. Win 7 will have security updates until 2020, they say.
