New Windows 10 setup (Previously ran 8.1)
Hey there, I see you're trying to get your PC back to Windows 8.1 after upgrading to Windows 10. You've made a bootable USB with Windows 10, but it's not accepting your MS Store key. Your question is clear—do you really need to reinstall Windows 8.1 first? Let's figure it out together.
Incorrect. Licenses for Windows 7/8 aren't compatible with Windows 10.
Upgrade your Windows version from 7 or 8 to 10 and it will activate automatically. After activation, use the provided tool to retrieve your Windows 10 serial number. Once you have it, you can perform a complete system reset and install Windows 10 using that key.
