Since there is no "DOS" in NTx OSs it is unclear what you mean...

Cannot be done from DOS (as in MS-DOS/Win9x)

From a command prompt (CMD.EXE) in Windows NTx you can Merge a .REG
file with: regedit.exe /s myfile.reg

And the Regedit REG file syntax for removing is:
Remove KEY
[-HKEY_CLASSES_ROOT\.zzz]

Remove VALUE
[HKEY_CLASSES_ROOT\.zzz]
"InfoTip"=-

Does not work for a ("Default)" valuename exactly. Use
@=-

But I suggest you have a full registry backup in advance.
