Change Outlook signature setting from the Registry

If you need to change which signature is used in Outlook without accessing Outlook directly, you can use this registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\Windows Messaging Subsystem\Profiles\Outlook\9375CFF0413111d3B88A00104B2A6676\00000002

There, you can change the value of "New Signature" and "Reply-Forward Signature".
