WinXP never went away, you just have to hunt around to find a legit, non-malware installation .ISO file. Minimum of SP3. Put it up behind a real good firewall, or run it as a VM, and get all the Windows Update patches that are available.
And then never, ever, connect your WinXP machine to the internet ever again. :-)

Or you can put a costume theme on Mint and have XP graphics... lol

I have two retail copies of XP Home Edition that have never been used. One box has never been opened and the other was opened, but never used. I bought both a week before MS quit selling them.
