1）去下載一個win11（查一查，許多地方告訴你怎麽下載）；
2）In search section of window tool bar(at bottom of your windows), type cmd, right click on the "command prompt", choose to open the cmd session as administrator;
3) change dir to your win11 dir, type
setup.exe /product server
type enter key
follow ..
That is it, good LUCK !
