Windows 10: Program Manager running message on shutdown or restart

This has only started in the past week. Program manager??? is running in the background I'm told when trying to shut down or restart. At first it was intermittently and now it's happening more often. I have not installed any new programs and don't know why this is happening. I tried a few fixes that I found on google and none worked. What can I do? It's really getting annoying.
Thank you.

My pc takes for ever to shut down when i restart

Suggest cleaning up your startup list .There may be many services / Apps you can remove on startup which is not needed on boot or during shutdown.
Before you shutdown the Pc check what is running in Task Manager as a program or service in not killing the process on shutdown

Would suggest cleaning up running apps and services -Autoruns, StartupMonitor,HighjackThis,
Malware Scan - Malwarebytes,ADWcleaner, Combofix

Strange message at restart and shutdown...

I have a Windows 10 Pro 64-bit system, updated from Windows 8.1 about two weeks ego, wired connection assigned to a workgroup. The system works just fine with one exception. At the time of restart/shutdown, the system may display the following message:

This message is more prevalent, if the restart/shutdown initiated right after login, or even prior to login, but shows up after 8-10 using the system and initiating a shutdown. My knee-jerk reaction was that the system has some malware, but had not been able to locate any. Admittedly, it does not mean the system has none...
Actions taken so far:

1. Scan system with Viper, Malwarebytes and Emisoft security software, came up empty
2. Scan system off-line via Kaspersky and BitDefender, came up empty

Disconnecting the PC from the network, for the purpose of eliminating remote connections to the PC, did not make the message go away. Evidently, this is a local logon by some process and/or scheduled task.
The disabled UIDs are:

• Adminstrator
• DefaultAccount
• Guest
• WDAGUtilityAccount

The enabled UIDs are:

• UID1, standard user account
• UID2, standard user account
• UID3, local administarator account

The message is coming from the file named "authui.dll":
Windows 10 DLL File Information - authui.dll
Reviewing the security event did not show any unknown account and the Task Scheduler shows mainly Windows scheduled tasks, with a few third-party application schedules.
Reinstalling windows isn't really an option, one of the reasons for the update is to preserve the application and user data.
Does anyone have an idea what triggers this message and how to get rid of it?
TIA...
