    Hi...I have an acer laptop. I was having a problem with my cd rom not working so I went to the microsoft windows site and followed the regedit steps to delete the upperfilters. I think I deleted too many because now my mouse and my keyboard is not working at all. I get a small box that pops up everything I turn my pc on that is labeled

    An invalid argument was encountered
    I can't find the disc that came with the computer but it wouldn't really matter because the cd rom doesn't work. I pressed F8 while it was turning on and I selected that restore to last known working or whatever and that did nothing. I pressed F8 again and selected reboot. That did nothing as well. I really do not want my whole computer because my most important thing on my computer is all of my pictures. If I loose them I don't have a copy any where else. (I know stupid mistake!) Please help!! Thank you!​

    Thanks for responding...I was in the regedit thing and I followed all of the directions microsoft windows said but I deleted more than 1 upperfilter. Everything works fine on the laptop except the mouse and keyboard. I can use the keyboard if I push F2 or F8 when it is loading. So I don't understand why I can't use it when windows loads. I had the setup up but I didn't want to mess anything else up so I just exited that. I also called microsoft windows and they couldn't help me over the phone. He told me to hit F8 and choose safe mode with networking but I couldn't use my mouse after that so he couldn't help me. My cd drive I can hear running when I put a disc in it but nothing pops up and when I go to my computer to run it that way it does not show up there. That is why I even to deleted the upperfilters. I wish I could just restore it to an earlier date but I can't get my mouse to move. I'm so frustrated with it right now! Thanks again for your response.

    Try safe mode with command prompt.

    run system restore from there.

    Type in the following command and hit enter key
