Behind a NAT you're safe even with Win9x. Idk about XP-latest, but you don't want to connect a fresh pre-SP installation right to the uplink cable. I wouldn't do that with any version of windows, even from the "windows server" line.

Do the zombie botnets still search for jurassic OSes to exploit? I feel like connecting the XP system to the Internet might be fine because all the botnets are searching for unpatched Windows 10 systems, maybe 8, 7, but not XP...

What is the cost for someone running a botnet to probe for old OSs also? They can just take something off the shelf and run it on someone elses machine.
