Back in the Windows 3.1 days, programs would store configuration data in .INI files stored in the C:\Windows folder.
Nowadays, of course, this isn't a good idea anymore and it is surpassed by newer technologies like the Registry, and saving data in the user's AppData folder. For lots and lots of good reasons.
Is there a SPECIFIC Microsoft reference article or KB article that discusses this change in best practices, or some other kind of documentation I can point at to say when this shift in thinking occured on Microsoft's part? Maybe some kind of "introduction to the Registry" document from '95?
I'm trying to convince a stubborn vendor to update their software.
