When Windows 10 was first released, Microsoft made it available as free upgrade for existing Windows 7 and Windows 8.1 users. At first, users only had the option to upgrade their existing Windows 7 or Windows 8.1 operating system to Windows 10. With the release of Windows 10 Threshold 2 (Build 1511), Microsoft changed this cumbersome upgrade process. Threshold 2 allowed users use their existing genuine Windows 7 or Windows 8 or Windows 8.1 product key to clean install and activate Windows 10. But all this is going to change with the expiration of the Windows 10 Free Upgrade offer program on July 29, 2016.
Let’s see one by one, what to expect once the free upgrade offer expires. What are your options available? Will you be able to activate Windows 10 using Windows 7 or Windows 8 or Windows 8.1 product key after July 29, 2016? How can you reinstall Windows 10 and activate it?
