Sorry my bad, it's meant for W11, i already posted in the W11 forum. In 11, SecHealthUI became windows app.

 

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:

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?

 

Remove-AppxProvisionedPackage offline SecHealthUI ERROR

SecHealthUI is executable belonging to Windows Security app

Windows security is not provisioned app and therefore it can't be removed by Remove-AppxProvisionedPackage

For a list of provisioned apps and what does "provisioned" mean and whether it is possible to remove any of these see:
