The thing is that currently I reverse-engineer the NTKERN.VXD module from Windows ME, and I need more info about VXD stuff. NTKERN is a real NT kernel (based on NT source code), but without lotta security stuff. Micro$oft tested all WDM stuff in Windows 98 before Windows 2000 was released. Windows 98 already contained all PnP and Power Management things that we all now have in Windows 2000/XP. Plus under Windows 98/ME I can quickly debug and test all my WDM drivers (though, real testing is only possible under Windows 2K platform). So, I need these books, especially "Systems Programming for Windows 95".
