Well, I’ve been putting off switching to Linux for a long time now. I guess Microsoft is going to force my hand.

Are there any 10-year-old Linux distributions that are still getting free support?

Actually, yes.

Debian has been supported since the early 90s, but admittedly that’s the only one I could name off the top of my head.

They’ve not been supporting the same release for that entire time, though. Debian requires you to upgrade to keep getting security patches.
