  1. Cannot activate Windows Defender


    Win10 Version 1803 latest updates - private pc

    I deinstalled Gdata-Internet-Security completely using "AVCleaner".

    After restarting the PC a system notice tells me to activate Windows Defender.

    By opening the appropriate window a notice appears, which tells me that the admin has not allowed to change the entry. And really it was impossible, because the switch was "OFF" and the switch was grey.

    I searched für solutions. One of this sides seems to be good:

    I tried all solutions-steps, but none was successfully.

    Any other idea?

    Thanks for answers!

    :)

  2. Cannot activate Windows Defender

    On my laptop "Toshiba Satellite L455" I did upgradation to W-10 from W-7 (original).

    There is no antivirus program on this PC.

    I wanted Windows Defender to run. But it says that it is switched off.

    Want to activate it.

    On opening Windows defender, there is no option to activate it.

    In step 2 of your suggestion, it says:

    "Windows could not start the Windows Defender Network Inspection Service on local computer.

    Error 1068: The dependency service or group failed to start"

    Can you pl give a method to activate the defender?

    Cannot activate Windows Defender

    problem in activating windows defender.

    The behavior you are describing is typical if there are remnants of a third party program installed.



    Run the McAfee Removal Tool again and reboot the computer…



    If that doesn’t fix it see the following:



    Go to Security and Maintenance, look in 'Security' and see what program is listed under Virus Protection. Windows Defender will not be enabled if there is a program other than Windows Defender
    listed.



    Have you tried the steps recommended in Problems
    starting Windows Defender in Windows 8/8.1/10
    ?
