Microsoft is aiming to make it that bit easier to upgrade to Windows 10 for existing Windows users with the Windows 10 November update, the first major update to the new operating system since it launched in July.
The update delivered a host of updates and improvements. One of those, it seems, is a tweak to the activation process that now allows users to perform a clean install of Windows 10 and activate it using a valid product key from Windows 7, Windows 8 or Windows 8.1.
When Windows 10 launched, it was offered as a free upgrade for anyone running one of those older versions of Windows. Many expert users prefer to take a different route and do a clean install rather than an in-place upgrade, but those doing so have found that they often couldn’t take advantage of the free upgrade offer, because Windows setup failed to detect an existing version of Windows.
Microsoft has now resolved that issue with the November Windows 10 update.
