But if a user unjoined the domain, they would not be able to log in to
the machine unless they knew the "local" administrator account password.
A domain account would not be able to log on.

So here's an interesting one based on the last comment:
By default all users in AD shd be able to join up to 10 machines without
any special privileges. How do you stop users from unjoin/rejoin
machines, even in an environment where explicit delegated rights have
been given to only a specific group of people to add/delete/move machine
accts?

Let's not forget how easy it is to circumvent the application of Group
Policy:
1) Unjoin the computer from the domain, reboot, install your software,
rejoin.
2) Reboot the computer and remove the network tap so GPOs aren't pulled
down. Install your software. Put the network tap back in.

To my knowledge, there's no built-in way to directly prevent the
administrator from installing software. However, you can use Software
Restriction Policies (Group Policy Editor > Computer Configuration >
Windows Settings > Security > Software Restriction Policies) to limit
software execution so that software only runs from a set of predefined
paths. By limiting the paths from which software can execute, you may
be able to severely-limit an Administrator's ability to install
software.
However, there are obvious problems with this:
1) If you're setting this in Local Group Policy (as opposed to
Domain-level), the Local Administrator can easily remove the Software
Restriction Policies
2) The obvious "hack" is to copy your installation file to a path where
software is permitted to execute, then to install said software to a
permitted location. Whether this is an acceptable risk depends on the
cleverness of your administrators and the sensitivity of your systems.
Beyond this, I don't personally know of a solution that doesn't involve
3rd party software.
Good luck,

Hey Guys,
Is there a way to restrict everyone including adminisrator rights from
installing softwares in xp pro? It should be done on registry or gpedit?
we don't want to use 3rd party softwares like winguard.
Thanks a lot!
