Display Your Own Error Messages

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!

NOTE :- Take the backup of your registry (by one of these Software's) before doing any tweak.
