I don't think testers should test this build or any other from this point on until this is fix, u run the risk of losing your digital license
Where is said that it only affected this build? I believe it's a MSFT activation server problem, on all builds.
It seems to affect anything from retail Pro to upgrades from Windows 7, with or without Microsoft account.
The Win 10 activation issue has been fixed! Microsoft already fixed it. Go to the Win settings and click the Troubleshoot. Then it will successfully activate the OS.
No mate, I mean right click on any item on the start menu do nothing. It happened since the build before the latest one.
