At the time I was there (2006 - 2010) and this may sound strange to some, I am sure that someone at Google had MSDN access but finding that person would have taken longer than hacking together a solution (which took a couple of hours in front of the VM instance). I don't doubt that at the if at the time I needed this that the TechStop guys (and gals) hadn't yet been dismantled I could have just said "I need an XP license for about a week" and they would have obliged. But I didn't have time to hunt down an owner, I didn't want to expense an XP OEM kit for this simple project that was a 20% thing anyway, and well TechStop had fallen way hard from being a resource to being a nop.
(Or I could be showing my [lack of] age and MSDN didn't have easy download access in the XP era)
