Windows Defender error code: 0x800705b4

I try to activate Windows Defender on your desktop current nine to run Windows 8. When I try to turn it on I get error: 0x800705b4, cooperation has expired. What's wrong?


I found this.

The fix is for Vista - I think that it is probably useful for Windows 8; so Windows 7 has been built on Vista and then Windows 8 was built on Windows 7.  The core of the operating system is always "there".

Windows Defender - impossible to activate the fix

This is a fairly easy procedure - don't forget to launch the window 'command prompt' as 'administrator '.

  • Publish with windows defender - error code 800106ba when I try to open Windows Defender

    I use windows vista sp2 32 bit op system.
    Windows Defender is set to automatic. but when I try to open windows defender, I get an error code 800106ba
    Please notify hw to enable this feature for protection.

    If you use another program (other than MSE) AV, Windows Defender may also be disabled. Examples of these other programs include but are not necessarily limited to: AVG, Kaspersky, Norton, McAfee, and Trend Micro.

    Hi the ball

    Kaspersky does not automatically turn off Windows Defender. However, it is recommended that, as usual, Windows Defender real-time protection is not enabled when Kaspersky is installed. Its a similar situation with Windows and Kaspersky firewall products that have built in firewall.

    I used Kaspersky products for several years and it has always been the case in my experience. I just tested with Kaspersky Internet Security 2012 race and I was luckily allowed to activate the protection in real time of the defenders of Windows and the Windows Firewall.

    I hope this helps.  :)

  • Windows Defender error code: 0x8050800c

  • may depend on windows Defender, error code = 0x800700ff

    Hi all

    Appreciate your help...

    Thank you!

    Best rgds,


    If you have Microsoft Security Essentials, AVG, McAfee, Norton, etc. installed, they have a conflict with Windows Defender, or turn it off.

    Microsoft Security Essentials has its own integrated version of the defender and it automatically disables the version of Vista in Windows Defender.

    If it's not:

    Turn Windows Defender on or off the information on the link above of Microsoft.

    Hope the above explains the common compatibility issues with Windows Defender and other security programs.

    See you soon.

    Vista SP1 or SP2 installed yet? (just a question, NOT a recommendation)

    Applications, (Norton and McAfee) are notorious for not not upgrade (or uninstalling) itself.

    1. download the Norton Removal Tool, save it to your desktop:

    2. close all open applications (that is, anything with an icon on the taskbar).

    3. After completing some you have a copy of your handy product key, uninstall Norton 360, LiveUpdate and all Norton Add ons via Control Panel | Programs | Uninstall a program (or Control Panel |) Programs and features, if you are using the classic view).

    4 IMPORTANT! -Online activate Windows Firewall immediately after the restart.

    NB: Now you're "working without a net": no to ANYTHING else online (e.g., navigation, reading e-mail, chat) until you have completed step #7 below!

    5. right click on the file that you saved in step #1 above, and then select run as administrator.  DO TAP not your keyboard until the race ends, then restart.

    6. do a clean install of Norton 360 2010 using your product ID & reboot:

    TIP: Do not activate or install additional modules of Norton (for example, Norton Anti-Phishing) immediately.

    7. manually and repeatedly run LiveUpdate until you get a prompt "no update more".

    8 test cycle.

    NB: Only one 1 firewall must be enabled at any time. If the Norton Personal Firewall is activated (after you have reinstalled N360), Windows Firewall must be turned off.

    Is there a message outside an error code?
    Is it possible that the message said you that Windows Defender does not work?
    If so, maybe the following could explain why:

    If you have the following AV, antivirus, programs installed, close your Windows Defender. Purpose of these AVs have their own advocates. 2 defenders on the same machine will create conflicts.
    Bottom line: it's ok. It's normal.
    List of AVs which will stop Windows Defender:

    Microsoft Security Essentials

    If the above does not apply to you, here's a way to restart Windows Defender:

    Start button > in the search box, type Services > press the Enter key > scroll to find Windows Defender, click on it >...
    topic status , it must be said... Has begun
    under Startup Type, it must be said... Automatic
    If it does not say that, right click on Windows Defender > click Properties > in the new window, make the necessary changes, as above > click OK when finished.

    I would check to see if you have a Trojan or a virus on your system.  He saw several cases with that error and it has been resolved by removing the Trojan horse and reboot your system. Once the Trojan horse has been removed, they were able to install from Windows Update again. It seems possible that your Windows installation has been damaged deliberately by a Trojan horse to avoid you update your system or remove the Trojan horse. Your first priority should be to clean your PC of any malware.
