Ok, so for my PC class I have to find 3 hacks that would mess up the lab's PC. Me and my partner are going to mess up the PC and then another team will try to fix it. The system on it is Windows 7. Anything that would stop the normal use or render the PC useless works. The conditions:
- Can't open the case
- Can't use the registry settings (due to how big it is, it would take the other team a long time to fix)
- Needs to be fixable (meaning, nothing that would mess that bad so it would require an reinstall) within 15-30 minutes (by my teacher, preferably not by the other team :)
- Can use the administrative tools
- No downloads (PC is not even connected to a network)
Note: stuff like create a fake, unclickable desktop by taking the desktop's screenshot and setting it as a background won't work as this has been discussed already. Also creating a reboot link and putting it in the autostart programs has been discussed. But anything of this type would be great to hear.
P.S. This is really for my college class, so no harm here, just pure lab fun :)
Added after edit: First would like to thank everybody for the input, some great ideas here. To clarify some things: - I have the admin account - It needs to be done in about 15 minutes, it needs to be able to be fixed in 15-30 minutes - Can't connect it to ANY network, since it's a lab PC and the college wouldn't allow them.
@Billare, yes, our teacher is a hacker at heart :)
Oh, and by the way, I don't think we are allowed to boot from another media, or mess with the BIOS, it is a Desktop Systems Administration class, and everything needs to be done inside Windows. I'll ask and see if we're allowed, if yes, then I can use some ideas from here. Thank again to everybody.
Edit 2: Let's try a different angle. How about disabling some non-vital services which will cause some annoyance. The main point, it needs to be a pain right from the start of using the PC, not in the long term use. Wow, my head is spinning some ideas from here, great, will let you know tonight what I used.
Moderator note: If you suggest ways to disable/break the computer, please include information on how to fix whatever it is you're breaking as well, if it is not immediately obvious.
One-liner answers, that fail to explain how they work or what the do, will be converted to comments.
