It's crazy how many Windows programs will run on Windows XP with 192MB of RAM and a single Pentium core yet now Windows 11 won't run on an average computer from 8 years ago (ignoring artificial TPM requirement and the actual minimum RAM way above 4GB.)

The number would be even a lot higher if you took away arbitrary compilation restrictions that make things run on Win10 or higher.

This isn't theoretical, I deployed a bunch of Windows XP VMs a couple years ago for a project because it would run Windows programs on almost no resources.
