MFC Files
"Many companies did, and still do, use MFC in their windows applications.
They would include those dll's (as they are licensed for redistribution)
with their install packages."
It would have come from any program that used MFC and included the dll in
their distribution package. Microsoft Office, for example, at least version
2002 and prior includes the mfc dlls in its distribution. Identifying
exactly which one put the copy you are specifically querying about is a
futile effort. You would need to look at every application installed on
your PC, see if the app uses MFC (many will) and then look at the install
package for the app to see if it put the exact version on your machine.
MFC (Microsoft Foundation Classes) is a set of class libraries that allow
C++ programmers to quickly generate robust Windows applications. The
libraries encapsulate some of the more complex code that is required for
coding C++ Windows applications. This allows for rapid development as the
programmer doesn't need to worry about, for example, how to create and
register a window class. Nor does the developer need to worry about what
styles to apply to a window in order to make it an input text box as opposed
to a label box. Nor does the programmer need to worry about what API or
message would need to be used to read the text from a window. This is all
encapsulated so the programmer need only to call a function or access a
property to get the data that is desired.

FWIW, the mfc42.dll currently on this WinME machine is ver. 6.0.8665.0,
Modified 6/8/2000.
