When I purchased my MBPro & iMac last year I had Parallels Desktop 10 and Windows 7 installed on the iMac but only got a Parallels 10 disc for the MBPro to install later. I've since upgraded to Parallels 11 and Win 10 on the iMac. Now I want to purchase Win 10 Pro, install & upgrade Parallels 10 to 11 and install Win 10 Pro on the MacBook. Does it matter if I install a OEM version? Or do I have to purchase a full retail version? The one I'm planning to order is Windows 10 Pro, OEM on a disc. Thanks for any help you can give.
