It's nice they are patching out of band products. Sadly when I was on travel the number of times I encountered crack/pirate versions of those OSes as very high. Most of the folk disabled Microsoft Updates.
Also, Windows 2000 was left with a glaring vulnerability on the Internet. That was never patched. Microsoft at the time said to put these clients and servers behind a firewall. Installing a firewall on W2000 did not patch the issue.
For users of Win2003 and XP, read this. https://arstechnica.com/information-technology/2019/05/microsoft-warns-wormable-windows-bug-could-lead-to-another-wannacry/
