Tool of the year?

Basically, it's a tool with which you can shoot out any type of registry settings! No need for custom ADM's. And it's free!

There is one drawback, and it is that it requires a client (Client Side Extensions - polregcl.msi). The advantage is that it comes as a regular MSI which means it could be distributed easily with a GPO.

The advantage over custom ADM's?
* Custom ADM's only supports strings and dword values
* PolicyMaker remembers previous settings

PolicyMaker consists of three main components, Group Policy Object Editor (GPOE) snap-in extensions, Resultant Set of Policy
(RSoP) snap-in extensions, and Client Side Extensions (CSE). All components are installed by the main product installation
(polreg.msi), however CSEs should be distributed to other computers using the much smaller polregcl.msi.
Although PolicyMaker components comply fully with Microsoft's documented interface specifications for extending Group Policy,
they do not come pre-installed with Windows. Software installation policy provides an ideal mechanism for distributing both the
snap-in and client side extensions.
