I know of no hacks to get SQL Server 2000 to install on an existing Windows 10 installation. There are probably forces against you from both within the setup program (which looks for certain things on the host system) and within the operating system (which prevents many flavors of older software from getting installed, mostly for security reasons but also compatibility, stability, etc). I have tried in the past and even with compatibility override options I came across the same failures every time.

A couple of ideas:

1. Use a virtual machine. This really is the simplest and most obvious solution.
2. Install 2000 then upgrade. Not really practical, especially if you want to use the Windows 10 installation you already have, but if you were doing this from scratch, you could install XP/Vista/Win7, all of which should allow you to install 2000, and then upgrade. Take care, though, because some methods of upgrading to Windows 10 will relegate all of your programs and services to Windows.old, and they won't run any more.

In either case, firewall the crap out of that thing, because the most recent security patches for 2000 are hard to find, and the ones that I found wouldn't install anyway...
