    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.

    Any suggestions?

    Google some dirty words and click on all of the search results that come up.

    Thanks for playing, but I said, PC is not even connected to a network, no Internet. I know what porn can bring, besides a warm feeling :)

    This may only be a bug on my machine, an ASUS running win 7 64 bit, but worth a try.

    If a portable HDD is plugged into the front USB ports and the puter is restarted it tries to boot in windows 98 for some reason.

    I took my machine back to the shop twice before I figured it out, and of course it behaved there because the HDD was still on my desk.

    Lol, you didn't have to bring your PC to the shop :) just format the portable HDD, Windows 7 doesn't have anything with Win 98, it's just probably that hdd had a version of Win 98 installed on it, that's why it tried to boot into it :)

    Are you authorised to bring with you and use a bootable USB device ?

    I think so, but it wouldn't cut it, since I have to do the stuff from Windows, and it needs to be fixed from Windows. It is a Windows Adminstration course afterall. So no bootable devices can be attached to it during the fixup process.

    Don't know how old you are but portable HDD's didn't even exhist in 98 - and this one has never had win98. I have 3 and it does the same thing with everyone.

    Computer/Windows/System32

    Rename the last to Sysetm32 if it will allow it.

    Might need to use something like ERD Commander to do it assuming they will allow you to use an external program. It's not an install, just a live OS that allows you to play with/manipulate/repair the original OS without it being loaded.

    Start up in safe mode, goto dos prompt

    CD Windows\System32
    ren *.dll *.txt
    ren *.drv *.txt
    ren *.exe *.txt
    etc...

    Lol, I'm 26 by the way and successfully using PCs from about 98. Throughout the years I've had the habbit of scraping dead PCs for parts, and mainly taking its HDD and putting it in an enclosure, thus making it a portable HDD. My ignorance is in the fact that I thought more people do that (and you did this since it boots Win 98), hence my statement above. So your problem was either:
    - A bootable win 98 on the portable HDD partition (which you say it isn't, ok). It might even be a repair live CD with Win 98 feel, but based on Linux
    - A bootable Win 98 installation on your PC.
    There is NO WAY Windows 7 would try to boot Win 98, it's just no way, no matter what you plug into it :)

    For everybody suggesting deleting such and such from the Windows directory, one tip, Windows has a feature called System File Protection I think, which won't let you delete this crap, or it would put the files back after reboot. So no go.

    Using device manager you can change IRQ values. Cause a conflict between the mouse and sound card on IRQ channel. Best way is to find the values used by the two devices and create an overlap between the memory address. for example 000000AA-000000BA on one device and 000000AF-0000000B5 on the other. When the user is playing sounds and using the mouse at the same time this should cause system lockups. Tricky to diagnose for newbies and a great way to cause a big deal of frustration.
