As the title says, I'm having a hard time getting Windows to activate. I have a custom built PC (not from a big manufacturer) that came with a Chinese version of Windows 10 installed. It wouldn't fully boot up (gave some error message in Chinese), so I tried to install English Windows 10 and hoped it would activate. Of course, no such luck. So I formatted the PC and installed Windows 7 Pro and activated with Daz. From there, I tried the gatherosstate method, install Windows 10 Pro, but it said I didn't have a genuine license. Back to square one, format, install Windows 7 again, activate with Daz, this time try upgrading with the Windows 10 ISO. Same result: No valid license. When I previously had this problem, I managed to get around it by using the Assistive Technologies update method, but the road has been closed. I'm stumped at this point. I guess I could try downloading the Windows 10 update, but I don't see why the two methods I used before wouldn't work. Is it possible the PC was activated with another version of Windows before and I'm somehow "locked" out of activating with a different version now? Does anyone have any suggestions what to try? FWIW, I followed the advice in this thread: https://forums.mydigitallife.net/th...te-upgrade-process.64770/page-83#post-1416509 But I skipped the step about installing the drivers in Windows 7. Is that really an important step? Could that be what's causing my trouble? Should I backup the drivers I have in my (unactivated) Windows 10 now and restore them on the Windows 7 instance before trying to upgrade? There ARE a lot of drivers missing in Windows 7...... But does it make a difference? Thanks in advance for the help!
