I'm administrating a "public" computer, that is the computer at our local church. We use it to record the services in Ableton Live, show lyrics with Easy Worship and so on.. On it we have Moonscape Protection which is a software that takes a snapshot of the computer and allows me to restore it on prompt or schedule it.
Often sommeone needs to install something, so they need an administrator account. (Windows XP) The problem is that every other month someone, and I don't know who, manages to install/get a virus. This leads to full chaos and a unusable computer at several services, and when I take away their administrator privilegies, they complain about not being able to install stuff they need.
I have thought about a program which generates codes you can only use one time to gain administrator privilegies to install a program, so that if anyone needs to install anything they have to call me to get a one-time code to install what they need, if I think the program they intend to install is safe.
Do you know about any programs which will help me? Thank you!
