Hi SysAdmins

CLSID stands for Windows Class Identifiers, which are  long number that represents a unique id for an application component.

CLSIDs can be used to target application component without knowing their name.

If we want to create a shortcut to a location in a computer without stating its name, we can use CLSIDs.

Lets say that you want to set the windows explorer start-up folder in windows 7 to open up My Computer.

→ Close all Explorer screens and hold down the Shift key.Now  right-click the Explorer icon, and select Properties.

Enter the following line in the Target field.

%SystemRoot%\explorer.exe /E,::{20D04FE0-3AEA-1069-A2D8-08002B30309D}

Now, when you click the Explorer icon in the lower pane, it defaults to ‘My Computer’.

You can use the following CLSIDs the same way to create targeted shortcuts.
