Win 10 boots...

I can't answer to the speed of Win-8 booting. I tried the Win-8 preview and went back to Win-7 after a month. They say that Win-8.1 is a lot better than Win-8 was.
My Win-10 TP is working well ATM.

 

Parallels 11 to Bootcamp Win 10 activation

Installed a licensed copy of Win 7 pro 64 bit under Parallels 11 at my new MacBook. Upgrade to Win 10 64 bit Pro with no problem with activation. Found out that 1 of my USB Token is not function properly and decided to switch to Bootcamp as both tech at
Microsoft and Parallels unable to resolve the issue.

Created a bootable Win 10 USB and proceed with Bootcamp installation (Unable to use Win 7 as the latest MacBook Bootcamp require Win 8 and above). Installed Win 10 without entering product key and after installation it did detect my product key for Win 10
from previous installation under Parallels 11. My USB Token now function correctly. However, under Bootcamp my Win 10 is not activated even though it detected my product key.



Called Microsoft and they suggest me to get a new copy of Win 10. That is not helpful at all. Unable to install Win 7 under Bootcamp to re-upgrade again. Is there any other way to resolve this?

It seems that Microsoft has a big problem in there update department windows 7 update has problems win 8 update has problems. Windows 10 update is so-so.
