    I cannot open Windows Defender Security Center -- I get a flickering wheel by my mouse...


    Hi, I have a new (to me) Dell 7040 Optiplex SFF running Windows 10 Home.


    I very recently reinstalled the operating system (twice). However, I am still getting "freezes" across different applications. Applications regularly freeze for about 15-25 seconds.



    I had ResMon running and saw that MsMpEng.exe is continually writing a constant amount to my SSD. About 450,000 B/sec. This is Windows Defender.


    I want to see what happens if I turn it off for a spell. However, I am unable to do this.


    I can go to Settings > Update & Security > Windows Security.


    But when I try clicking on "open Windows Defender Security Center", nothing opens at all.


    HOWEVER, my mouse cursor gets a Blue Wheel that flickers on and off rapidly. It is basically blinking. This effect persists until I restart my computer.



    What is going on? Any ideas or suggestions?

    :)

    windows defender & security center services keep turning off


    Are you running any other AV or did you have one running in the past? If you didn't use an uninstaller for the AV, then the remnants of it could be causing the problem. Normally any time you install an AV it disables Defender by default.

    If you are getting any error codes please list those, that will be helpful in helping you.

    As torre suggested, might be a good idea to do a reset or even a reinstall.

    Open Windows Defender Security Center in Windows 10  


    I noticed tonight that windows defender or the windows defender security center both are not in my all apps list. When I start ms services it shows that defender is running. I just can't seem to open the security center. When I try to via the settings window, nothing at all happens. No error message, nothing. I rebooted and still nothing.

    My calculator and photo viewer also quit opening but right now I'm more concerned about windows defender since I don't have an alternate av on my system.

    Windows Defender Security Center Won't Stay Open


    When I open Windows Defender Security Center, it opens and then closes itself.

    I’m running Windows 10 Home, v1703, with the latest updates.

    I run Norton Security as my primary AV & firewall with the latest updates.

    I did a system reset in the last couple of months.

    I have the latest Defender updates according to: https://www.microsoft.com/security/p...tions/adl.aspx

    Defender seems to be functioning, but generating the following errors:

    • Event ID 3: The Windows Security Center Service was unable to establish event queries with WMI to monitor third party AntiVirus, AntiSpyware and Firewall.
    • Event ID 16: Error while updating Windows Defender status to SECURITY_PRODUCT_STATE_ON.
    • Event ID 1000:
    Faulting application name: SecHealthUI.exe, version: 10.0.15063.0, time stamp: 0x58ccbce5
    Faulting module name: SecHealthUIDataModel.dll, version: 0.0.0.0, time stamp: 0x58ccbc8d
    Exception code: 0xc0000005
    Fault offset: 0x000000000015b847
    Faulting process id: 0x27f0
    Faulting application start time: 0x01d2f12745cc2b1f
    Faulting application path: C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\SecHealthUI.exe
    Faulting module path: C:\Windows\SystemApps\Microsoft.Windows.SecHealthUI_cw5n1h2txyewy\SecHealthUIDataModel.dll
    Report Id: bcac3ab1-757d-47fb-8d4f-c089173b11e0
    Faulting package full name: Microsoft.Windows.SecHealthUI_10.0.15063.0_neutral__cw5n1h2txyewy
    Faulting package-relative application ID: SecHealthUI

    I have tried options 3 and 5 in this tutorial: Turn On or Off Windows Defender Real-time Protection in Windows 10. Options 1 and 2 aren’t available to me since the settings window won’t stay open. Option 4 isn’t available for Windows Home.

    As I said above, AFAICT, Defender seems to be working, but the Defender Security window won’t stay open and it’s generating a lot of errors.

    Any suggestions for troubleshooting and/or fixing this issue?
