    Windows Defender wont turn on?


    Hi,I recently disabled Windows Defender but when i went to turn it back on it just hangs,and times out with the error 0x800705b4.
    I've been into services and it's there but it wont let me start it and comes up with error 126 module could not be found.
    Thanks in advance for any help.

    I tried different things... registering dlls, looking in msconfig, trying to manually start the service in services.msc...

    Maybe all the above helped.... Windows Defender started working after I noticed that Windows Security Essentials was installed as well... in Control Panel | Programs. After removing Security Essentials, Windows Defender worked great... like a racehorse out of its pen.
