I can't say for sure, but not long after I made the jump to Windows 11, I noticed a pop-up window appearing/disappearing every 20 minutes. Too fast for me to read it. So I used Powershell, Task Scheduler and msconfig to narrow down the cause... named in said subject. The next two photos capture the pop-up 20 minutes apart.
Here's the task schedule:
Disable it in the Task Scheduler Library and the pop-up goes away... which also suspends a valuable task.
The photo below is the only concrete reference to a 20 minute interval.
I am uncertain if the change occured as a result of moving to Windows 11, or a Norton patch/update as a result of the new OS. Any gnus from the gurus?
Thanks for considering my post
