Hello. It is no longer get a code for w7u and i dont want to risk to damage the bios with windows loader...
The option i have is to reinstall windows and use slmgr -rearm every few months, unless someone can enlight my ignorance.

No i dont want to use linux or any variant. I dont want to use Unknown OS because they usually end badly. w10 will be obsolete soon and w11 will damage my computer for sure. I just want to browse the web and play my old games and not much else.
