Microsoft allows Windows 7 and Windows 8.1 users to upgrade to Windows 10 free of cost. Although, to successfully activate Windows 10, users are required to upgrade directly from Windows 7 and Windows 8.1. Once Windows 10 is installed, Microsoft activates it automatically. From the next time users can clean install Windows 10 as the product key gets attached to the Microsoft Account and the hardware configuration.
The free upgrade system sounds perfect for both Microsoft and Windows users willing to take advantage of the free Windows 10 offer. But there are reports that suggest otherwise. Sometimes, either due to technical reasons or hardware issues, Windows 10 failed to activate after an upgrade, leaving users in a difficult situation. Also, some users may not want to take the upgrade path and may like to clean install Windows 10. How to get Windows 10 to activate after a clean install the first time? For all these reasons, Microsoft seems to be getting ready with a solution. Users will soon be able to activate Windows 10 using their existing Windows 7 or Windows 8.1 product key.
