Windows doesn't store the version anywhere, it's hardcoded in each of the 
installed runtimes and the mscoree.dll returns one of them - for 
GetCORVersion it returns the highest available, for other functions 
depends on what the executable requires.

But remember, we are just _emulating_ windows and sometimes we need to 
pretend we have a different version.
