The Startup Registry Key Changer allows network administrators to add, modify or delete registry keys automatically as soon as someone logs onto the computer, in a matter of seconds.This is especially useful in the following circumstances: for example, should you have a piece of software that requires a serial number to be entered into every computer, and stores its data in the registry, all you would have to do is enter that data into the configuration program, and upon next logon on the workstations on which this product is installed that registration data would automatically be entered.

Another example is for housekeeping - supposing people keep installing software you don't want them to, and it creates registry entries (for example, to make it run on windows startup), you could specify the configuration program to automatically deletethese entries.
