This is so far my understanding regarding about the free upgrade on my laptop. 1. I installed a fresh clean Windows 7 from a USB from one of the ISO's from this link forums.mydigitallife.net/threads/56439-Windows-7-ultimate-x86-x64-ISO-Download 2. Used the Windows Loader 2.2.2 for activation. 3. Installed every single update available from Windows Update. That's how my system is currently running and using. I got the free Windows 10 upgrade notification. Is this means is safe to follow the upgrade without the worry about any key input or activation problem?? Or do I still need to use Microsoft Toolkit to activate?? Also about the fresh clean install Windows 10, do I need to upgrade first then do the clean installation or I can go directly from Windows 7 to clean installation Windows 10. Thanx
