:::The Charles Petzold link describes no such thing. It says that Windows 1.x runs on VGA cards but treats them as EGA. Which is absolutely true. But "added support for the VGA graphics adapters" very much implies actual VGA resolution support. You might as well say that the earliest development versions of Windows "supported VGA" by virtue of being able to run on VGA's emulation of CGA adapters. That would be just as misleading.
