Did you buy a desktop computer from Aldi?
My first computer ran Windows® 98. It lasted for over ten years.
The one I am currently using has Windows® 7 - X64. It may have gone out of regular support, but access to the Extended Service User patches is available using a script written by a user on the Ask Woody blog/forum.
To me, computer operating systems are like an automobile. They should be operable forever, as long as the parts and accessories for it are available.
