Windows 10: "Program Manager This App is preventing shutdown"

Hi all, lately when trying to shut down a blue screen shows up displaying: "Program Manager: This App is preventing shutdown", and I'm given the option of "Shut down anyways" or "Cancel". If I choose shut down it will do it without issues, and if I click Cancel it will go back to the Desktop. I checked Task Manager and there's no "Program Manager" listed, also the CPU usage at idle is 0%, so everything looks normal. Additionally I checked Task Scheduler and Services, and nothing unusual. Thanks for any feedback,

:)

 

Unknown Program Preventing Shutdown and Updates

There is an unknown program preventing my computer from shutting down. When I click shutdown it says "This app is preventing shutdown" but there is only a generic app icon, and no name for the app. I have to select "shutdown anyway" which isn't allowing
Windows Updates to be installed.

I've checked forums and could not find a solution which worked for me.

Task Manager tells me there are no program running. There are no "blank" programs on my app list in control panel. I've used sfc /scannow
in the Command Window and it came back negative. I've turned off all Non-Windows programs for start-up that I don't need (I have a couple drivers which are necessary for my computer).

Any help would be greatly appreciated.

 

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

 

Mystery app preventing Windows 10 shutdown after update.

After much searching, and trying many, many suggestions, this is what eventually worked for me:-

Run Windows System File Checker
Your Windows PC comes with an in-built system file checker utility program. It can scan your system files and let you know if there is some corruption over there for which you get smashed
with the error message “Task Host Window Preventing Shutdown”. You must follow these simple steps here to run the Windows System File Checker,

• Press the Windows Logo Key + X from your PC
• From the drop-down list select the Command Prompt(Admin)
• Click on Yes if prompted for permission. It will open the elevated command prompt on your system
• Now, type in the following command and press the enter button
• sfc /scannow
• Then, wait until the System File Checker continues the process of scanning. Press Y if the program asks for permission to apply the fixes for your missing system files
• Finally, Restart your PC once again and check if you can get over the problem there

I found the above on a list of several suggestions, which are on the following link, but the above was what removed the problem for me.
