Win2000 is NT5.0, XP is NT5.1.
And just because there's similarities between OS/2 and NT doesn't mean NT was based on OS/2 - although there's obviously some influence there... and heavy influence from VMS

. Btw, NT can run other subsystems than just Win32 - posix, for instance. And iirc there was some OS/2 support as well?
Gothi[c]: I sorta prefer config files to GUI config, actually, my problem with linux is that there's so many different incoherent formats, and that files are different places on different distros, despite that unified hierarchy project whatever.
As opposed to a sane process of keeping your app and config files to your own directory structure, no, it is not.
Ho humm, I still think the registry is a better idea than <whatever> config file format. There should have been better/easier hive-file support though, so you could place the hivefile next to the application for portable apps.
