You can get LTSC through microsoft resellers. Last I heard, you have to buy at least 5 licenses to be in Volume Licensing, but if you only have one computer, you can buy one LTSC license ($270-$300) and then 4 low cost filler licenses (I think seats for something were $10-$30 each?)

And the LTSC license is an upgrade license, so the computer needs licensing for Windows already (maybe needs Pro and not Home, too).

But it ends up being a large amount of money to run wierd windows.
