Now I'm curious, what exactly were you making where the win32 documentation was insufficient, but the "one weird trick" blog TheOldNewThing was helpful? Did you buy any books on win32 or check stackoverflow?

I've found win32 to be a bit hard to find documentation on sometimes (the official documentation is complete, but sometimes know which hook or function to use is up for debate, stackoverflow has good answers there), but overall it's a very good API that gets out of the way and lets me just build.
