When you try to run QBasic in Windows 2000, you are greeted with:
'qbasic' is not recognized as an internal or external command, operable program or batch file.
You can find QBasic in the help file, but you can't find it on your disk or on the Windows 2000 CD-ROM.
I guess they forgot to copy it.
For now, mount your Windows NT 4.0 CD-ROM and switch to the folder containing qbasic.ex_. Then type:
expand qbasic.ex_ %systemroot%\system32\qbasic.exe
expand qbasic.hl_ %systemroot%\system32\qbasic.hlp
