At least Windows 2000's version of Regedit will remember where you left off every time you run it, which can be quite annoying.
To make Regedit forget where you were last and start with a default screen, run regedt32 and delete the value of the "LastKey" entry for the key:
HKEY_Current_User\Software\Microsoft\Windows\Current Version\Applets\Regedit
Then make every user entry in the permission list have read-only access to the above key. (Remove inherit, copy existing rights, and uncheck the "Full Control" box.)
Prevent Regedit from remembering last key viewed.
