A. As we saw in the last registry tip, the Windows 2000 version of Regedit.exe now remember the last key that was open when you start the application.
The second major change is the introduction of a favorites menu to which you can add you most used and 'favorite' registry keys (you would have to be sad :-) ).
Another change is the addition of the ability of new RegEdit to save files in the old (REGEDIT4) format from the command line, using a command-line switch -ea.
REGEDT32.EXE has not had any major functionality changes.
