Well, I get the theory, but my mind just doesn't like thinking about it. 
;-) Thanks for explaining.

Maybe I haven't expressed myself clearly. What I mean is that it does 
the comparsion of the strings first with the thread locale and if that 
returns negative result (string s not equal)  then it tries to compare 
the strings again using the system locale.

I think "find_entry" is almost correct. Only honouring the the default 
UI lanaguage is missing (as introduced in W2K). I think it belongs 
between step 3. and 4. and that the user default UI language 
(GetUserDefaultUILanguage) is tried first and system default UI language 
(GetSystemDefaultUILanguage) just after that.
