Entropy sources under WinXP


If one has a non-interactive application[1] running under WinXP with
no hardware TRNG attached, what are reasonable sources of entropy for,
say, seeding PRNGs? I know some use the Pentium Time-Stamp Counter,
but that's going to be a lot less than 64 bits. Where else can I find
a decent source?

1. So mouse movements, keyboard timings, etc are out.
