If you install this build of the Windows 10 Insider Preview on a PC and it doesn’t automatically activate, you can enter the product key from Windows 7, Windows 8 or Windows 8.1 used to activate the prior Windows version on the same device to activate Windows 10 by going to Settings > Update & security > Activation and selecting Change Product Key. We have received a lot of feedback from Insiders on making it easier to activate Windows 10 on devices that take advantage of the free upgrade offer to genuine Windows by using existing Windows 7, Windows 8 or Windows 8.1 product keys. The product key changes coming in Threshold 2 offer a third alternative. This update would include a lot of fixes and new changes in the user interface, changes that should have originally come up with the final version of Windows 10 but delayed for some reasons. Now you can use a corresponding edition of Windows 7, Windows 8, or Windows 8.1 product key on that device where you are clean installing Windows 10. According to an anonymous source, on Tuesday morning, Nov 10, Microsoft will release the Threshold 2 (Fall Update) update for Windows 10 operating system. This build eliminates activation hazard in Windows 10. The latest Threshold 2 preview release, build 10565, contains a welcome change.
