This question already has an answer here:
Where do I ask questions about the Windows operating systems? Be it Win 8, 7 or XP.
The questions that I want to ask may not be strictly related to a problem I am facing, but related to files and features of the OS itself or asking just because of my curiosity. For example, I want to know the purpose of the file "Bootvid.dll" in a Win 8 OS. Or, for example, I want to what "hal.dll" is.
Are these questions appropriate for Stack Overflow or Super User? If not, please recommend some SE sites in which I can post such questions, because I am interested in getting into the guts of the Windows OS. Open to all suggestions.
