Some "slightly less than documented" Windows API's

Duncan Mackenzie: I wrote an article back in August 2002 on some of the API calls that were documented as part of the Microsoft settlement agreement… but in the end, I never published it… so here it is for your viewing pleasure;

There are some really cool functions hiding in here… one most notable is the IsUserAnAdmin function. There’s been more than once that I needed to know if the user was an administrator; before I would just check to see if they could open a file for read/write/locked access in a known administrator only path. This is much better ;-) Thanks Duncan for pointing this out.
