When you try to delete Microsoft Outlook from the desktop, you get the warning message "The Outlook Desktop icon provides special functionality and we recommend that you do not remove it." If you like, you can edit that message to display whatever you want. In the CLSID's subkeyfor example, {00020D75-0000-0000-C000-000000000046} for Microsoft Outlook you'll find the value Removal Message. Edit this value to whatever text you want, and your warning message will appear whenever someone tries to delete the icon. This is just an example. Follow the suit for customizing the error messages for other icons too!
