    Missing system files

    While dealing with tech support from a peripherals company regarding a mouse
    problem, they had me check for certain system files, and we determined that
    several appeared to missing, including input.inf, msmouse.inf, and
    hidusd.sys. Someone suggested I use System File Checker (sfc / scannow), but
    this did not restore the files, and give error messages telling me that there
    were corrupted files but they could not be repaired. Any ideas about what
    might have happened to these files (and any others that might also be
    missing) and more importantly, how can I get them back.

    Vista's equivalent of a Repair Install is the Upgrade in Place. You insert
    your dvd at the Vista desktop and select Install Now. Then select the
    Upgrade Option. This of course does not disturb your apps, files, or
    settings, but it will result in a new copy of the OS, thus correcting all
    file corruptions. SFC not being able to correct the corrupted files
    suggests that an upgrade in place is the only effective solution.

    If you have a Vista gold dvd and have upgraded to SP1 you will need to
    uninstall SP1 first and reinstall after. Otherwise you will get an error
    message that the OS on the computer is newer than the one on the media and
    will not be able to proceed.

    RE: Missing system files

    Hello Larry,
    I suspect that that those files that are missing are not present in the
    \windows\inf folder
    I need you to check if those files are present in the folders under
    c:\windows\system32\driverstor\filerepository.
    There are then multiple copies of each of those files each in their own
    folder something like msmouse.inf_12345678
    You should take the most up to date file and copy it back to the
    c:\windows\inf folder
    Thanks,
    Darrell Gorter[MSFT]

    Re: Missing system files

    Hi Colin,

    Thanks for your reply. The disk I have is the Academic Upgrade version, but
    I have installed SP1. Do I still need to uninstall that before proceeding
    with the update? How can I uninstall SP1, and is there anything to do first
    to make sure there are no negative effects of the uninstall, or is it likely
    to be completely safe to do?

    By the way, it would sure be nice if the screen that comes up when the disk
    is installed said something about upgrading and repairing. I was afraid to
    hit the Install Now button because I wasn't sure I wouldn't have had to
    completely reinstall all of the many applications I have installed since that
    would need to be written in to the registry again. It sounds like that would
    actually not be an issue, though.
