What do you rate for Windows 2000 in 2021

[pcalvert]

Windows 2000 is a great operating system, and an ideal OS to use on old hardware that is too old to run a recent version of Windows or even GNU/Linux. Regarding security concerns, there are ways to harden Windows 2000 to make it much harder to infect, and there are many uses for a computer that don't involve going online. I would probably install a firewall and completely block Internet Explorer from being able to access the internet, or I might even disable the network adapter and use the computer as a standalone system with no network access whatsoever.
