I have a classroom with ~20 PCs. One for the teacher and all others are for students. They all have pre-installed licensed Windows 7 Home Premium (cause reasons) and reinstall OS to another is not an option :( Also they all are in same work-group (in one net).
Is there any tools (like Active Directory \ VNC \ "Microsoft Garage Mouse without Borders" etc.) which can do exactly the same operations at exactly the same time on all students computers from the "main" teacher-pc? For example: I start this "magic" program in small window, it connects to all PCs (if it can), then I move my mouse inside it to the left and all mouses on all PCs moved the same way. Press Start - it will open Start on all student-PCs. It's some kind of botnet program (I suppose), but it will help a lot.
VNC not good, cause you must reconnect every time and do the same operations x19 times - eh... AD as I read didn't support Home Premium (or I misunderstood?) - eh again. If there is no such tool\tools, what kind of OS (may be some Linux distributives) can do such thing?
