GetModuleHandle doesn't increase the reference count so you probably
shouldn't call FreeLibrary.

I believe Windows initializes with version 2. At least that's what my
old test says (line 105):

https://code.reactos.org/browse/reactos/trunk/rostests/apitests/wininet/InternetOpen.c?hb=true
(free to use under LGPL... I can make it explicit in the source file,
 or help with getting it in Winetest format if desired)

By the way, the same applies to winhttp in case you're interested:

Thanks!
