I have not tried this, only searched the Apple support site.
According to this site:
"Windows
To use iPod prior to version 2.0, your computer must meet the following system requirements:
PC with built-in FireWire or Windows-certified FireWire card
Windows Me
Windows 2000
Windows XP Home or Professional
MusicMatch Jukebox Plus (included on the CD)"
Take a look at the compatibility chart and the footnotes here.

It looks like once you get to iPod 1.1 software you are Windows compatibile.
First & second Gen iPods can run up to 1.3 iPod software, the last pre 2.0 software released.
I can find no mention of hardware limitations on Windows compatibility.
