As a working student I manage a couple of computer laboratories in our school. Basically I do the usual stuffs to keep the computers on its working state. There's this one subject that involves an activity in Windows(Windows 7) network configuration and these operations needs an admin account. All computers have two separate account for the students and the Admin, so occasionally I input the admin's password whenever they need to set some configurations on the PC.
My question is, how can I create a temporary admin account on which I can set some restrictions like blocking any program installations. I've already googled for this kind of solution but I cannot find a good one that fits to this kind of situation. But if ever you guys got some good and much efficient alternative options for this kind of situation then please comment your suggestions and recommendations below.
