Script to rename part of a share path

[Thomas2z]

I roll out a windows image every few weeks to our classroom computers. The instructor PC has 4 profiles, each with a class share folder on the desktop. The student PC has 4 profiles, each with a shortcut on the desktop to the corresponding instructor class share folder. (Student-1 share points to Instructor-1 folder). The computer names are always xxx-yyy-zzz where x is the city, y is the room number and z is the seat number in the classroom.

 

I would like to have a script run that renames part of the path in the shortcut on the desktop to replace the first 7 characters of the computer name with whatever the current computer name is. Can anyone figure out how to do this?
