If you like old console games turn it into a retro gaming arcade. I did this with an old Dell Optiplex running Win10 by adding additional hard drives. Once I got the games and front end installed the way I liked, I didn’t need an internet connection. Now I can play every game from every console/PC - a dream come true for the 12 year old version of me.
Great username / post combo.
If you want to keep running Windows you could try 0patch. I used it to patch my Windows 7 PC until it died and I acquired a Windows 10 PC. I will probably do the same again until I update to Windows 11 when I feel like it.
