Hi Frank,

If you wish to fix Windows Security, please start a new thread and post the following logs. Post the link to the new thread here.

Step 1:

Step 2:

  • Download defender_diag.bat. Right-click on the file, click Properties, Unblock, and OK. Run the batch file as administrator.

(The Batch file queries Defender-related settings/Policies and outputs the results to a log file named defender.log. Upload this log to your OneDrive and share the link here.)

Those entries have no significance. Those entries show up in my system as well. You'll see a lot of Not Found entries for any operation you do. Usually, most of those entries have no significance.

You may try this if possible.

Download this REG file and save it to a folder named c:\reg\

Launch AdvancedRun (from Nirsoft) and start cmd.exe as TrustedInstaller.

In the TrustedInstaller Command Prompt, run:

  • reg.exe import c:\reg\securityhealth.reg
  • exit

This restores some essential registry keys used by Defender.

    //Does this makes sense, to analyse, or would you suggest a different scenario?//

    Yes. That should also work. Please zip the PML before sharing.

    Hi Ramesh, Hi Frank,

    I read a bit about procmon trace, it seems to be a debug program to collect data, where you can clear the data, then start a recording and log the data of events. It seems you can download procmon somewhere on the windows site, install it and with some Control Commands, you can clear, start and stop the recording?

    Which would be the best scenario to record.

    • Launch services in the search bar
    • scroll down to Windows Security
    • Start the Service, which results in this error:

    • close the services
    • Stop recording.

    Does this makes sense, to analyse, or would you suggest a different scenario?

    The Platform folder is found, and the service is intact, yet the service fails to start. Frank faces exactly the same issue. A ProcMon trace from one of the two systems might help.

    Hi Ramesh, Thanks again for looking into this.

    I downloaded and ran the batch file. It showed the log in the notes app, however the defender.log was not created.

    I saved the log shown in the notes app as defender.log and uploaded it to here: https://1drv.ms/f/s!At3helIxGZsEknlHW5PQcVhJDUtO?e=8UqqhV
