    My laptop, which runs XP Home SP3, appears to have corrupted registry hives.
    The computer will get stuck in the black Windows XP screen and if I try to
    boot in Safe Mode it gets stuck in the mup.sys file.

    I researched the problem and have found the apparent solution is to replace
    the registry hives with the ones in the c:/windows/repair folder.

    The "system" file that is supposed to be in the repair folder is not there.

    I researched that and nobody seems to have a straight answer. Every thread
    answer I read is sending the OP all over the place but not answering the
    question directly.

    Where can I find another copy of the c:/windows/repair/system file?

    I looked at my desktop (which runs XP Pro) and there is no "system" file in
    the c:/windows/repair folder either. The only file in there (just like in my
    laptop) is system.bak

    Can someone tell me where can I find another copy of the "system" file that
    is supposed to be in the repair folder?

    Thanks

    The Repair folder is the only place where you will find a backup copy of the
    registry files. However, it would probably useless because it does not get
    updated automatically. It is likely to be several years old, which means
    that it is out of step with the many updates that have happened since. Why
    it disappeared I cannot say.

    On Windows 7 (and perhaps on Vista), Windows updates the registry backup
    files automatically about once a week. On WinXP/2000 you need to create a
    scheduled task that does it for you. An even better method would be to
    create an image of your installation, using a tool like Acronis DriveImage.
    Unfortunately this won't help you retrospectively.

    You can, in future, use ERUNT to backup the registry, and recover

    There is probably not a problem with your mup.sys file. XP has gotten
    past mup.sys and is trying to load the next item It is what comes
    after mup.sys that is the causing the system to hang - usually (but
    not always) i8042prt.sys.

    Sometimes with this issue, you just need to wait with mup.sys on your
    screen... - sometimes you have to wait a while for XP to get past the
    file after mup.sys. I would wait several minutes. This may allow you
    to get past the problem and resume troubleshooting whatever your issue
    is.

    Describe your current peripheral situation - keyboard, mouse, printer,
    USB devices, wireless, etc. and start suspecting them first. Anything
    new added since the system last booted successfully?

    Unplug everything except the keyboard (if a desktop). You only need a
    keyboard to boot, and try your Safe Mode operation with just a KB and
    see what that does for you. If you boot okay, start plugging things
    back in one at a time until your system hang again and then you have
    identified the culprit and can fix the real problem. I usually find
    it is some mouse issue. If you have a wired keyboard - use it. Get
    down to the simplest configuration so you can at least boot.

    Depending on what led up to the situation (any new hardware. drivers,
    updates?), from the F8 boot menu you can also choose:

    Last known good configuration

    which will load the system using the information from the last time XP
    thinks it booted successfully, then you can undo whatever caused you
    to get it this situation in the first place - usually uninstalling
    whatever you installed or undoing your last change.

    If your system (appears to) hang up mup.sys and then reboots after
    some period of waiting (I would wait several minutes), from the F8
    boot menu choose:

    Disable automatic restart on system failure

    and let the system fail again. If you see the blue screen of death,
    it will probably have all the information you need to figure out what
    is wrong and fix it.

    There is nothing wrong with mup.sys and probably nothing wrong with
    your registry. Copying in old registry files is tedious and exacting
    and may not be necessary at all. It is a good exercise though.

    This is why when you Google the problem of a system hanging on
    mup.sys, you see so many ideas of what to try and they never work
    because nobody seems to understand that the problem is not mup.sys at
    all - it is what comes after it.

    Sounds like a W32/Alureon-variant rootkit infection.

    What anti-virus application or security suite is installed and is your
    subscription current? What anti-spyware applications (other than Defender)?
    What third-party firewall (if any)?

    Has a(another) Norton or McAfee application ever been installed on the
    computer (e.g., a free-trial version that came preinstalled when you bought
    it)?

    Was the computer fully-patched at Windows Update before this problem started
    and is KB979683 or KB977165 found in Add/Remove Programs (after making sure
    the Show Updates box at the top is checked)?

    First of all, I agree with Jose. Try his suggestions. If you still
    want to access a backup copy of the registry, I suggest that you follow
    the procedure in the article:

    "How to recover from a corrupted registry that prevents Windows XP from
    starting"
    <http://support.microsoft.com/kb/307545>

    But since you don't have a c:/windows\repair\system file, you can make
    the following changes to the Microsoft Procedure:
    1) Download and create a Live Linux Boot disk [such as Knoppix]
    Knoppix: <http://knopper.net/knoppix/index-en.html>
    2) Boot your system from this CD. This has several advantages in that
    Linux ignores Windows file protections. Because of this, you can
    skip "Part 1" of the KB article above and go straight to Part 2.
    You can perform the Step 2 tasks using Linux to access your
    backed-up copy of the registry in your "System Volume Information"
    directory. Also, if all else fails, you can use the Linux disk to
    backup your files to a USB drive or to a networked drive before
    you re-install Windows.

    Good Luck,
    John

    Well, if the system will not boot, there is no way to implement that
    KB. The KB It is a good exercise though and actually does work as
    described, but probably not needed fo this silly problem.

    Using Last known good will load the registry snapshot created from the
    last successful boot, but still leave the "what caused it" problem to
    be resolved. Self inflicted I would imagine.

    If Jose wants to implement the KB, he must boot on something and you
    can boot and then implement the KB from the XP Recovery Console - a
    bootable Recovery Console CD can be created by following this tutorial
    also from from Jose (too many Joses).

    I am still suspecting a keyboard or mouse driver update (something
    US8) that lead to the yet to be specified issue. I can purposely make
    my system appear to hang on mup.sys and BSOD any day, any time. We
    are good friends now - this mup.sys hang situation and I.
