For WindowsXP and some 2K (I think SP4 fixed this particular issue, 
memory dump the lsass process and search for the hex string "76 78 01 
26". A little ways further down and voila, cleartext password for 
currently logged in user. It's in unicode format, btw.
I think the latest rumor is that XP SP2 is going to clear this issue up 
so if anyone can find the hashes in the registry (ala lsadump for stored 
services passwords) then we'll be back in business after everyone starts 
patching.
Need a tool to dump process memory? pmdump of course.

Arne also has Pstoreview which may help you a little.
