I understand that pretty much everything is "still there", one exception that I happened to notice recently is that there is no debug.
C:\Users\Jim>debug
'debug' is not recognized as an internal or external command,
operable program or batch file.
Certainly true of 64-bit Windows, may still exist in 32-bit versions, but I haven't got any to test! ISTR that it was still in 32-bit Win 7 via command.com, rather than cmd.exe.
Sorry, nerding again!
