CMD Opens and Closes Rapidly Every 20 Minutes

I found the threadposted by a person who can see what the CMD screen says before closing; it happens too fast for me. I also read that Autoruns is a tool that can remedy this problem. So I'm hoping to get some modified advice for my circumstance. This started immediately after I upgraded to Windows 11 through Windows Update (22H2 Build 22621.755). Every 20 minutes starting on the hour. Can't see what the CMD screen is trying to do. Thanks for your time.

Looking at the screenshots, it appears that the NortonCleanupTask is the culprit.

See also this thread where disabling the task resolved the issue.

Open Task Scheduler, right-click "NortonCleanupTask" and click "Disable"

(Ref: Batch file runs on startup and every 20 minutes .. starting at 6 minutes past hour. | Norton Community)

    My phone doesn't record videos. It's a means for me to talk with another person who also has a phone.

    Use your phone to make a video of your monitor. After you see the command box flash on and off, stop the recording and then play back the recording in slow motion until you can see the open command box.

    If you're able to post a screen shot of the open command box, please do that. Otherwise, tell us exactly what the command box says.

    I was able to solve problems with my own PC on two separate occasions by doing this. The beauty of it is that you will know exactly what is in the command box, without the need to guess from other sources and hoping that you guessed right.

    Thanks John DeV.

    1. No malware found.
    2. shell:startup was empty
    3. I couldn't find anything that indicated "cmd"
    4. the blip screen stopped blipping after the "delete all" step. So I am enabling the non-ms items I disabled, one at a time, to see if I can isolate what triggers the event.

    My regrets for delaying so long. I will return once I finish step 4.

    Kind regards.
