What's the purpose of Create GUID tool in Visual Studio?

create-guid, guid, visual-studio, visual-studio-2008

Solution

It's a very useful tool for those who develop and maintain COM components. Need to introduce a new registry-exposed class or interface? You need a new GUID. With this tool you click "New GUID", select "Registry format", copy it to the clipborad and then paste into a IDL file.

Problem

Visual Studio has a Create GUID tool (Tools > Create GUID). What is it for? Can you remember what was the last time you used it? I just can't imagine why i should copy into the clipboard a new GUID with that tool.
