Windows Defender has stopped working and I have error 0x800106ba

• Desktop Window Manager has stopped working and was closed

  One of our machines (HP Pavilion dv7 Notebook PC running Windows Vista x 64) will receive the error "Desktop Window Manager has stopped working and was closed" with lots of close error. He reappears (as well as all windows flasher to non-aero, then back to aero) in a few minutes, spends about 5 times per hour.

  I did some research on this and have already taken the following measures without a bit of luck:

  1 run the command chkdsk / SFC scan - nothing found via chkdsk, SFC found some issues fixed, and some, it did not set. Them that it solves not all related to Windows Sidebar, which I do not / does not start.

  2. put updated drivers for ATI Radeon 3200HD - this had a lot of new questions. Installing caused newer drivers ATI catalyst to no longer work with errors during installation and popup errors at startup. After trying several solutions workaround to try to get installed it, I ended up coming back to the driver that came with the laptop, that are properly installed and working without error. I am skeptical of update of this stable driver as a solution to the dwm.exe error.

  3. this problem just started yesterday, that occur with not a lot of changes. Other than updates of windows (I think that .NET framework and a few other updates installed), I replaced NOD32 antivirus with Bitdefender antivirus. The system was stable with bitdefender for about 2 weeks, so I'm not convinced that this program is causing the error.

  4. the event viewer shows the following:

  Failing application Dwm.exe, version 6.0.6002.18005, time stamp 0x49e02696, failed module ntdll.dll, version 6.0.6002.18881, time stamp 0x51da3d16, exception code 0 x 80000003, offset 0x00000000000461f0, process id 0 x 124 error, start the application time 0x01cea0365a457adc.

  Offset, process id and start on time all vary, but there are a lot of these application errors in the viewer all screaming Dwm.exe like the failing application.

  What should be my next course of action?

  You do not receive an error but a caveat. NTStatus results (the set of codes execption used by ntdll - the failed module) begin to 0 for no error, 4 for information (you should never see this), 8 for putting guard and C for error.

  It's your specific error.

  //
  MessageId: STATUS_BREAKPOINT
  //
  MessageText:

  Problem is, you shouldn't have breakpoints. Breakpoints are set by debuggers and stop the execution of the program to the State of the program can be examined. There should be no breakpoints in a retail system. More breakpoints are inserted into memory during execution of the program in a debugger. They tend not to do in the actual file.

  So here are two assumptions, either you have no exit code, IE test code (driver?). Or you have a running program that behaves like a debugger (which is suspect).

  Each of the three towers of programs, services, and drivers in increasing amounts. So restrict the possible culprits.

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
  For each driver in the list, additional useful information is displayed: load address of the driver,
  Description, version, product name, company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
  Control Panel - device - Graphics Manager - note the brand and complete model
  your video card - double - tab of the driver - write version information. Now, click on update
  Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
  Uninstall - REBOOT it will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
  with their own software and drivers and all other main drivers that you have.

  Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
  Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
  BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
  each installation.

  Always check in the Device Manager - drivers tab to be sure the version you actually install
  presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
  in particular that) so to install a driver - reboot - check that it is installed and repeat as
  necessary.

  Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
  manually by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
  Updates, that leaves about Windows updates but it will not install the drivers that will be generally
  older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
  get new manually if you wish.

• Vista: All Windows updates suspended / "Module of Windows Installer has stopped working and Will Close."

  On my installation of Vista, all windows updates no longer work.  If I try and run them from Windows Update in Control Panel one starts to run but then it just hangs.  At the same time, I get a message "Windows install Module has stopped working and closes".  If you look in the services, it is crushed, but restarts.  The update remains always hung.  It doesn't matter what update I try and run, I always get the same result.

  When the computer is shut down, it also tries to automatically install updates.  These also hang on the first, which means that I have to force power off the computer.

  Don't know if this is related, but I don't think that SP2 already installed - it kept if crush (don't remember what was the error message).  When I restart in safe mode it tells me that I'm still on SP1.  I followed all the suggestions on how to get SP2 installed for the error I received, but nothing has worked.

  Do not really understand what I have really installed a lot of "_" on the PC, it is a "clean" installation (about 1 year now).

  Any ideas?  Really, I don't want to have to do a re-install, but I suspect that is where I'm heading unfortunately.

  Hi AndrewInNZ,

  Thanks for visiting the site of the community of Microsoft Windows!
   
  I would like to ask you some questions for a better understanding of the issue:
   
  (a) did you try to temporarily disable the security software and check if updates are smooth?
   
  (b) you are using a firewall in addition in instead of the windows firewall? If so disable (temporarily) of the third party firewall and look for updates.
  It is usually caused by a 3rd party firewall that it blocks the internal ports.
   
  Check out WERCON for more information-
   
  1) Click START | wercon.exe type in the search box start and click on enter.
   
  (2) select "View problem history", under 'Windows identified problems' with the right button on a problem, and then select "view problem details. Click "Copy to Clipboard" export to text document
   
  Also reset the Firewall setting:
   
  1) Click START | type FirewallSettings.exe into the start search box | Click on FirewallSettings.exe above | Select the Advanced Settings tab. Click 'Restore Defaults ' | Click on apply (if Hi-lighted) | Click OK

  Check the status of the service as well:

  Log in as administrator-

  Start button | Control Panel | System and Maintenance | Administration tools

  Double-click on Services

  (Provide the administrator password or a confirmation if prompted to do so.)

  Right click on the 'Windows Modules Installer' service, and then select Properties.

  Select the general tab - make sure that the startup type is manual

• Windows Installer has stopped working and access is denied installation KB942288-V3

  original title: Windows XP SP3 installation problem

  My windows installer has stopped working. I tried several 'fixed' found on the net, but nothing is done and would be grateful if someone could guide me through the solution.   Windows XP, SP3.

  In 'Services', 'Windows Installer' has been designated 'disabled '.   I changed this "manual".

  msiexec /unreg works ok.
  msiexec/regserver gives an error: "an event could not invoke any of the Subscriber.

  I have downlaoded and ran KB942288-V3 and got ' Setup error.   Access is denied. "

  I watched the permissions in the registry and seems to have all the permissions are ok, but maybe I'm looking in the wrong place?

  Thanks for any help

  Hello Kaiser,

  I would say that if you update your PC from SP2 to SP3 all your files will remain same.

  Once you do a new Installation or a custom don't store all your network cards and other device drivers.

  Why you are posting in the forum, IE?  Maybe the reason why you try to use the CP is to enter Internet Options?  If so, you can do it without the help of Windows Explorer (at least on your operating system) starting (using the Task Manager if necessary): control.exe inetcpl.cpl

  Otherwise what your problem probably means is that you have added something new to the root of the control panel which is not compatible with your OS, causing thus the Windows Explorer (not IE) crashing.  In this case, the same way you could get in Add Remove programs without involving Windows Explorer by starting: control.exe appwiz.cpl

  You can get help more informed by post on a forum that specializes in performance and Maintenance of your operating system.

  Hi 1pinktink,

  Welcome to Microsoft answers forums!

  a. What is the exact error message that you receive?

  b. don't you make changes to the computer before this problem?

  c. what anti-virus program you installed on the computer?

  This problem may occur if there is a conflict between windows defender and the security software installed on the computer.

  I suggest you try the following steps:
