Ok, I tried everything everyone else tried and had the same result... no success. The window kept popping up on startup regardless of my account time.
So I decided to go and look at the services, figuring there had to be some service that was required to authenticate the request.
So I opened task manager and low and behold there is a service called "WpcMonSvc" and in my case this was stopped. I then right click this service and choose open services in order to go looking for the boot setting for the service. I find the entry in
this services list as "Parental Controls" and then right click this entry to choose "Properties". Here you will see the boot setting for the service. In my case, the boot setting was listed as manual. I have changed this to automatic and, viola, the notification
on boot is gone as I think the service is now running and can check and set the permissions appropriately.
I hope this helps others, happy at least that my notification no longer shows up though!!
Cheers.
