I clone PCs and, sometimes, the cloned PCs have the same TV ID.  When that happens, I go to the system registry, and change the MAC address, and a new TV ID is created.  Now, this can only be done locally on the PC , not remote, since, it takes affect on reboot, and I wont know what the TV ID is after reboot.  Is there a way to generate the TV ID BEFORE I change the MAC and reboot, so, I can connect after I change the MAC?
