Defender of the error 0x800106a window does not light

get window Defender error 0x800106a not turn on

This problem can occur because another security application is used or the Windows Defender service has stopped, or components of Windows Defender are corrupt.

You install any new programs recently? Windows Defender is not designed to protect against the extent of malware. If programs like Microsoft Security Essentials and Windows Defender both run, your system may experience degradation in performance and other problems caused by the conflict of two services providing real-time protection at the same time. I recommend that you keep the Defender off if another application of security protection is running.

If no similar security application is installed, I suggest that we have follow these steps to resolve the problem:

Step 1: Check the Windows Defender service
=================================
1. click on start, in the search box, type: "services.msc" (without the quotes) and press ENTER. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
2. double-click on the service "Windows Defender".
3. click on the 'general' tab. Make sure the "Startup Type" is "automatic". Click on apply. Then please click on "Start" under "Status of Service" to start the service.

If the problem is not resolved, please refer to step 2:

Step 2: Save the associated DLL files
========================
1. click on start, type "cmd" (without the quotes) in the box start the search. Right click on CMD listed above and click 'run as administrator '.

2. in the command prompt, type the following and press ENTER to each order:

regsvr32 atl.dll

regsvr32 c:\windows\system32\wuapi.dll
regsvr32 softpub.dll
regsvr32 mssip32.dll

3. close the command prompt, and then run Windows Defender.

  • When I click to open thunderbird but the e-mail window does not appear until the icon shows the app closed, how to fix this?

    To start thunderbird, I click on the quick start on my toolbar icon, it highlights that if beginner, then a few seconds later, returns to the closed state. No e-mail window never appears on the screen. When I check the Task Manager, thunderbird does not appear in the list of running applications, but one or two processes show running on the Details tab (one first process by clicking on the icon, and then another if I right click and try to open one of the windows in option). I am running Windows 8.1. It worked well earlier in the day, so I have no idea what happened past. Restart the PC does not help the issue. How can I get the windows thunderbird appears on the screen again? If I can't, please send the instructions to backup all the associated email and address profile information so I did not lose anything... then uninstall and reinstall thunderbird and restore all the info related to my current profile. Thank you.

    Thanks for the reply... still not sure what happened, but I ended up uninstalling and reinstalling bird t. Everything is back to normal after that. So your solution can work, but I don't have the chance to try it. My solution, but is not ideal, was effective and the problem was solved.

  • After installation, the main Thunderbird window does not open (send emails)

    Thunderbird has been an automatic upgrade this morning (02/05/14).
    Now, when I open it, it opens and I can even see the preview of the main screen when I hover over the icon in my launch, but the main window does not open.
    If I right click to compose a message, I can, and it does not send. But I didn't see the main screen.
    I closed it, closed the process of thunderbird. I moved my profile and reinstalled Thunderbird.
    Same problem ever time.

  • Inspiron 5749: BIOS update fails with the error 'Dell id does not match ".

    Hello

    I'm trying to update the BIOS of the Laptop Inspiron 5749. I downloaded the update file 3443A 07. EXE from Dell support website, where the update is supposed to be compatible with my system:

    -Dell Inspiron 3443/3543/5749 system BIOS;

    -Version A07.

    -Pull out the date 18 November 2015.

    I tried to install the update by using the utility to update the BIOS available in the start menu (after pressing F12). The update failed with the error message "Dell id does not match" or similar.

    Running the update of the session Windows don't seem to have any effect either.

    It seems that the update is only compatible with Inspiron 3443.

    Where can I get the update of the correct BIOS for my laptop? Any help is appreciated.
