[edit] Removing access to Outlook Express
If you want to remove access to OE, simply alter these registry entries:
[HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Outlook Express\InstallInfo] "IconsVisible"=dword:00000000 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\>{881dd1c5-3dcf-431b-b061-f3f88e8be88a}] "IsInstalled"=dword:00000000 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\Oc Manager\Subcomponents] "oeaccess"=dword:00000000
Sometimes a disconnect/reconnect is needed to really have the OE icon disappear.
[edit] Uninstalling Outlook Express
The above just hides OE. To remove it, use the procedure How to manually remove and reinstall Outlook Express. (Maybe someone can post a batch file?)
