If you had a choice. Would you use Windows 7 Professional or Windows 8.1 Pro?
I would use windows 8.1because of the amount of features it has compared to 7 including the Windows app store.

Get 8.1 with KB 296-(i cant really type the numbers on KW -__-) update which rolled out in 2014. It fixes most of the issues people originally had with win8 causing all the negative critical reception...
The problem was that when windows 8 was released, it was worlds apart from se7en, without the original start menu, the desktop being regarded as an app, etc. But its obvious that underneath everything is the same. The start menu button came back with 8.1 so it feels much closer to windows 7 now. Besides, the metro style of win8+ is beautiful :3 I never used the windows app store but I like the newer one better
