I've scoured the internet and it seems there is no solution to this issue STILL... Similar to many others, I have Windows 10 activated on my Boot Camp partition and a failed activation on my Parallels 11 Boot Camp VM. On Windows 8.1, I was able to activate both by calling the activation line but that's no a possibility with the whole "digital entitlement" scheme. I really only need Windows for SolidWorks at this point so I may attempt to see if I can go back to 8.1 and still activate. My question is: Can I just leave my Windows 10 Boot Camp VM deactivated and use SolidWorks with Parallels? I know I won't be able to install updates after 30 days, but I can always reboot in to native Boot Camp to do so, right? Thanks for advice in advance!
