After updating Windows, causing KB981957 XP BSOD, C000021a Service Control Manager error at startup in safe and normal mode.

After you apply this update, the system starts more (secure or normal) and gives the BSOD error above.  Manual removal of the patch Recovery Console fix the BSOD using batch spuninst.txt in the patch folder.  The affected system is an AMD Athlon 2400 + with 2 GB of RAM and XP SP3.  All other updates installs successfully.  I scanned viruses with Avast, Dr Web CureIt, ComboFix, Malwarebytes and TDSSKiller.  The system seems to work fine without the update.

It seems to be a problem with the Win32k.sys file in the patch, but I ran out of utilities to solve this problem.

Hello

The solution is to report the problem, so the update can be set to not to do so. Microsoft
may already be a fix, or work on it, or it could be a new problem. He
There's even a phone number to make it easier.

Certainly keep good backups that there could be an underlying hard disk or hardware
issue.

========================================================

Here is the solution for the coooo21A except use it when you can just get the fixed update
is not the method I want to use.

STOP: 0XC000021A

Can be a difficult problem to solve, and you indeed need a technical help in a real store of the computer
(not the leeks and the glances at a BestBuy or other BigBox stores) or system manufacturer support.

Cause

This error occurs when a subsystem of mode user, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), irremediably compromised and security can not be guaranteed. In response, the operating system goes into kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, it is one of the rare cases where the failure of a user mode service can stop the system.

Incompatible system files can also cause this error. This can happen if you restored your hard disk from a backup. Some backup programs may skip restoring system files which they determine are in use.

Solve the problem

Run the kernel debugger is not useful in this situation because the error occurred in a user mode process.

Resolve an error in the user-mode device driver or system, third-party application service: Because the bug 0xC000021A control occurs in a user mode process, the most common culprits are third-party applications. If the error occurred after the installation of the new or updated device driver or service system, third-party applications, the new software should be removed or disabled. Contact the manufacturer of the software on a possible update.

If the error occurs during the system startup, restart your computer, and then press F8 to character-based menu that displays the choice of operating system. In the WindowsAdvanced Options menu that results, select thelast known good Configuration option. This option is most effective when a pilot or a service is added at a time. If the error is not resolved, try to manually remove the offending software. If the system partition is formatted with the (FAT) file allocation table, use a MS-DOS boot disk to access the hard disk of the computer. If the system partition is formatted with the NTFS file system, you may be able to use Safe Mode to rename or remove the defective software. If the defective software is used as part of the start-up procedure of the system Safe Mode, you must start the computer by using the Recovery Console to access the file. If a room newly installed if material is suspected, remove it to see if that fixes the problem.

Try running the emergency recovery disk (ERD) and allow the system to repair any errors that it detects.

Solve a problem of file system do not match: If you have recently restored your hard disk from a backup, check if there is an updated version of the backup/restore program available from the manufacturer. Make sure that the latest Windows Service Pack is installed.

It's my generic bluescreen convenience store - you can try Mode safe mode as suggested in article

Here are a few ways to possibly fix the blue screen issue. If you could give the blue screen
info that would help. Such as ITC and 4 others entered at the bottom left. And all others
error information such as codes of STOP and info like IRQL_NOT_LESS_OR_EQUAL or PAGE_FAULT_IN_NONPAGED_AREA and similar messages.

BCP2: 8C013D80

Tcpip.sys - address blocking 0 x 0 00000000 000000000 DateStamp 0 x 000000000

  • By using the system restore before computer restart after updating Windows 10...

    I chose to try the upgrade of Windows 10 on my laptop primary.  Because of the long installation times, I started late in the evening then followed finishing (or almost) the update the next morning.  Until I sat down to 'start' I spoke with a friend who had just completed an installation of two heavy day of problems.    Although I am good enough to solve computer OS and software installation problems, I was very reluctant to go forward.   After serious soul searching I elected continue to use Windows 7, I don't really like.

    That's why I chose to use the system restore before restarting my computer needed complete Windows Update 10.  I chose the previous restore point before the update of windows 10 and ran through the entire procedure and then restarted the computer after the restore point.

    Everything worked fine and I was able to do the foregoing... Except that I can't do updates of security that have been uninstalled.   The Windows Update screen repeat "you must restart your computer...". "with the reboot by holding the active button.

    This window doesn't go away even after reboot, and I can not "check for Updates".

    Does anyone have any suggestions on how to reset this program if I can do all the updates except Windows 10 security.

    Thank you for any assistance.

    Sorry, System Restore does not cancel the major updates, that's why a lot of automatic updates delete all system restore points. The tool that is appropriate in this case would be a restore Image. If you have not created an image before the upgrade, then you are out of luck.

    You indicate that you get blue screen after the update is finished installing. Or do you find only the blue screen when you perform certain functions with the system which requires a State of transition of power (sleep, restart, etc.)?

    You've got bugcheck SYSTEM_THREAD_EXCEPTION_NOT_HANDLED caused an access violation.

    You can download the contents of c:\windows\minidump on your SkyDrive? The discharge can take probably a few additional details.

    To treat blue screens, following general tips:

    Consider running chkdsk on all partitions.  Leave complete chkdsk on each partition and see if that helps.

    Also consider running SFC/scannow.

    If you start in safe mode, do you still feel bugs? What if you do a clean boot, or boot device?

    Other common suggestions include ensuring drivers are up to date (including video drivers), but also to ensure that you use the latest version of the BIOS.

    Consider the memory with memtest86 or Windows Memory Diagnostic test. Note that memory that pass the tests isn't necessarily good memory - he not only failed a review.  Examine systematically to eliminate the system RAM - run with a few modules for awhile and see how things are going. Then try the other modules.

    For the case of memory corruption such as you seem to be experiencing, it may be useful to use Driver Verifier.  To activate the... Driver Verifier start-> verifier.exe-> OK-> create standard settings - > then-> the names of the drivers select in a list-> next-> sort by provider-> select all non-Microsoft drivers-> finish and OK your way out of the dialog box.

    Then restart and use the system as you normally and wait for a problem.  In case the system does not completely start after activation of the Verifier, boot mode safe and run driver verifier and tell him to remove the changes.

    Wait for an error checking to happen after you have enabled the auditor as described and then transfer it to your SkyDriveand provide a link.

  • Firefox runs very slowly after updating Windows 10

    Saturday, December 12, 10 Windows spent an age of update itself, with several reboots. Since then, the navigation is horribly slow with Firefox, although my internet connection is always very well (fast my Smartphone using Microsoft Edge). I have two PCs, and both seem to have been affected in the same way. Using the Task Manager, I see that Firefox uses a lot of CPU most of the time - often more than 50%. Even typing and scrolling are very slow, not just downloading.
    I disabled all my add-ins and plug-ins, run in safe mode, rebooted and reinstalled Firefox without result. So far, I'd say that Firefox is the fastest browser. I think that Firefox updated itself 42.0 version a few days, so I have a suspect that this slowdown has occurred just after a Windows Update.

    Update: Windows update itself again today and, like magic, Firefox is again well. So problem solved.

    Hello;

    Let me welcome you on the HP forums!

    I read your post on WiFi often disconnect and wanted to help.

    Whenever someone comes here running Win10 and complains about something just suddenly does not work, I immediately suspect driver updates Windows.

    Unfortunately, Win10 forces automatically updates driver on each of us, without our knowledge and without our permission - and in this case, a work PC is suddenly 'broken '.  This could happen to you.

    You must go to settings, update & security--> Windows Update.

    Then choose Advanced Options--> history to see when the updates have been applied last.  If you see one that include device drivers, who might be the problem. So, if you can, you should see if you can restore the drivers that are causing the problem.  Do so you by going into Device Manager, see if the device is still listed and so, trying to restore the last driver update.

    And if this resolves the problem, then disable future driver updates by using the information in the link: http://www.tenforums.com/tutorials/48277-driver-updates-windows-update-enable-disable-windows-10-a.html

    If you don't see the driver updates recently, then try the steps in this thread: HP PC - wireless network and Internet troubleshooting
