@phnt @skylar When it comes to software actually designed to run on the kernel, Linux - Linux does a much better job than windows.

Linux's SYSCALL ABI has not changed, so you can install whatever version of systemd/Linux and the elf prime that does DeCSS will still run.

Although windows tries not to change anything and thus maintain legacy compatibility - many versions of old software is broken on windows 10.

With the source code of the software, you just compile it, fix up any compile failures and suddenly you have a working binary.
