I did a clean install of Windows 11 but it won’t accept my old Windows 10 key. Everything else runs fine, but the “Activate now” message keeps showing. I thought the free upgrade covered that. I’d like to fix it without reinstalling again. Is there a way to reuse a Windows 10 key on Windows 11 safely?      

Upgrading to Windows 11, I explored the software and system features more closely. Testing a kmspico for windows 11 in a safe environment allowed me to understand how modern activation methods work and how the OS handles keys, which was both informative and helped me learn the internal mechanics of licensing.
