KB925902 update causes STOP:c000021A fatal error at boot

    My PC automatically downloaded update KB925902 yesterday. With the update
    installed, the PC would boot into a BSOD with "STOP:c000021A {Fatal System
    Error} The Session Manager Initialization System terminated unexpectedly with
    a status of 0xc000026c (0x00000000 0x00000000) The system has been shut down.

    None of the start up options would get the machine booted. It's running XP
    Home SP2 with all prior updates installed.

    In the end, I got the Recovery Console up and running and removed the
    KB925902 update by running 'batch spuninst.txt' This removed the BSOD problem
    and allowed the machine to boot OK.

    So, the machine's now running but I'm without the KB925902 update and have
    disabled Automatic Updates to prevent it installing for the time being.

    Two possibilities seem to exist:

    1) There's a problem with the KB925902 update which needs to be fixed.

    2) There's some other incompatibility on my machine which is causing the
    BSOD when the KB925902 update is applied.

    Any thoughts please? I gather elsewhere that the STOP message above is
    indicative of a security or permissions problem with system processes
    towards the end of the boot.

  2. Most likely. Do you have overclocked your machine? Or "tuned" otherwise?

    An update...

    I've just called Product Support Services.

    They tell me that the KB925902 update is incompatible with my XP Home SP2
    and they recommend that I hide the update to prevent its installation.

    I can't see the sense in this. KB925902 was issued to fix a security
    vulnerability which I would then still have, so this doesn't fix the problem.

    No overclocking or tuning applied.

  5. Hm, which appications/services are running in the background and
    were running while applying the update?

    Do you have looked for updated system drivers (BIOS, chipset etc.)
    for your system?

    IMHO braindead conclusion?

    The fix stated here works perfectly. I was receiving this same exact error

    What reason did PSS give for the incompatibility? 925902 had installed
    w/out problem on 2 WinXP Home machines here.

    I'm glad I'm not the only one with this problem, then.

    I've now installed the hotfix for the Realtek HD Audio that MS issued and
    then re-installed KB925902. The system then crashes as before, so I've had to
    go and remove it again through Recovery Console. I can't find a way of
    telling Microsoft Update to stop installing it, so Automatic Updates will
    have to remain off for now.

    After the disappointing telephone support I got (see above), I'm going to
    try and raise a support call by e-mail. Anyone else had this problem or got
    any ideas?

    Thanks

    JB

    In another thread above, jrutz suggests installing KB925902 with the PC
    running in Safe Mode. This worked for me - I now have a PC with KB925902
    installed which still boots! I can only assume that, with the PC running
    'normally', some process was stopping the update installing properly and
    causing the subsequent boot failure. Booting in Safe Mode has, presumably,
    allowed the update to go in properly and prevent the problem.

    I also run AVG Free and that seems fine, although I did install the
    additional Realtek HD Audio hotfix as advised on the AVG website.

    Hooray, now I can get on with my Easter holiday.

    Hi there, me and some guys using XP Home have the same problem with the
    halting system after the Hotfix.

    So can you tell me where I can find the 'batch spuninst.txt' and if it gives
    me any info on how to remove the hofix again? - I have to say here I never
    uninstalled a hotfix by using the console, so I dunno how to do it. thanks,
    Daniel

    You need to boot your PC from a Windows XP install CD (*not* a PC recovery
    disk some vendors provide with them). When you start XP from the CD, one of
    the options is to launch the Recovery Console.

    After answering a few questions, you should end up with a C:\WINDOWS prompt,
    or something similar.

    At this prompt, type

    cd $NtUninstallKB925902$\spuninst

    Then type

    batch spuninst.txt

    All being well, a handful of files will be replaced with the original
    versions (before the update was installed) and when you reboot your machine,
    it shouldn't blue screen.

    When the machine reboots, you should disable Automatic Updates temporarily.

    Then go to Control Panel and remove the KB925902 patch from Add/Remove
    Programs (make sure Show Updates is ticked at the top of this page).

    You then need to go to the Microsoft web site and download the KB925902
    patch without installing it.

    Then, boot your PC into Safe Mode by pressing F8 when the boot process starts.

    When it's booted into Safe Mode, run the KB925902 patch you downloaded
    earlier and reboot again normally.

    All being well, this should install the patch without trashing your machine.

    Thank you very very much for this workaround. My Notebook crashed with this
    fatal error Wednesday in the evening.

    It took me 7 hours of my life to find out what happened and fixing it.

    Thank you Microsoft for nothing!!! No patch can help on this problem for
    normal customers because they can't even boot their systems!

    FYI: My System is a BenQ 5100E with a Windows XP Pro (upgraded from the
    original BenQ XP Home recovery set) OS.

    (paraphrased):

    Boot PC from Windows XP install CD.
    Launch the Recovery Console.

    In Recovery Console:
    cd $NtUninstallKB925902$\spuninst
    batch spuninst.txt

    Disable Automatic Updates temporarily.
    (Note: You can also do this in the Recovery Console: disable wuauserv)

    Reboot normally.
    Go to Control Panel \ Add/Remove Programs and remove the KB925902 patch.
    (make sure Show Updates is checked at the top of this page)
    Manually download KB925902 from Microsoft web site without installing.

    Boot your PC into Safe Mode.
    Run the KB925902 patch you manually downloaded
    Reboot again normally.

    -----------------------------------------------------------

    Great call JB, had exact same symptoms on Dell Optiplex OEM pre-install with
    Windows XP Pro SP2.

    FYI: All booting options, including all variations of Safe-Mode and Last
    Known Good failed miserably. Since my machine had Automatically Restart on
    System Failure enabled, all I would see is the initial Windows XP graphic
    with the scrolling bar at the bottom, then bang, reboot.

    When I enabled Safe-Mode from the F8 screen, I would see the AGP440.SYS
    driver load last in the character-based mode and then as XP changed into GUI
    mode...reboot.

    I had none of the driver conflicts MS has identified, so far, to blame.
    Just the likelihood that one or more of the replaced files, gdi32.dll,
    mf3216.dll, user32.dll, or win32k.sys, was locked in a way that the patch
    installer could not overcome.

    MS Support was even less helpful for me, offering only upgrade in-place,
    with possible/probable loss of data stored in All Users and possibly
    Administrator profiles too. Instead, I have a fully recovered system, with
    no loss at all.

    Thanks for posting your solution.

    I had this same error, i thought i had a bad piece of hardware. it happened
    with both windows 2000 pro and windows xp pro sp2. thankfully, i found this
    solution. I uninstalled both patches kb925902 and kb890859 from my machine,
    and then it booted. i have yet to try and reinstall it in safe mode, but at
    least i have a solution for now.
    when i first uninstalled kb925902, my machine would still not boot, so i
    then uninstalled kb 890859 which i also found in this site.
    thank you very much.

    I was installing the SP2 update to XP Pro in Safe Mode. The progress bar got
    to approx 50%, then I got an "unstable system" message recommending uninstall
    from Add/Remove Programs, followed by a "failed to install SP2" message.
    After rebooting the machine, I got a BSOD with the C000021A {Fatal System
    Error} and 0xc000026c 0x00000000 error codes. It's not my computer
    (thankfully), but I was wondering if anyone had this issue with the SP2
    update or has it just been with Security Updates? Any reason for SP2 to have
    this type of error? Will the fix for J Barker's problem work with mine?

    I forget the machine specs other than it's custom built (not by me) with an
    ASUS P5P800 motherboard and 1gig of RAM

    Thanks in advance

    JBaker's way almost worked but something missing, windows could not
    autenticate.

    I reformat and reinstall the damn Windows XP again (too much investment).
    Then one by one istalled the updates and tested.
    Until installing KB 890859 it was still okay.

    Now only KB 925902 was excluded from the system.

    I tried to do this and I get the message "There is no floppy disk or CD in
    the drive." I have the recovery disk in the CD drive. What should I do?
