This doesn't have windows 11.  It's windows 10 s mode and the upgrade to windows 11 is free. the option takes hrs to come up. Basically go through set up.  After 3 hrs or so of restarting and downloading it will upgrade to a new version of 10, then that version takes time to register it meets the requirements. The Microsoft app that reads your system... Gpu, memory, etc helps.  It's PC health checkup or something like that.  But you get it in s mode so it's from Microsoft.  It will help Microsoft's site recognize the computer can handle windows 11 and then eventually it will give the option.  I put 4 hrs into setup. Went to bed leaving it plugged in and letting it update on its own.  Basically choose the fastest update option.  The one that lets the machine restart on its own.... Let that happen over night and then by morning the option will be there and after another 2 hrs.... You are in.  Besides the long wait the computer is actually great... I'll update more after I install this memory.
