Mystery app preventing Windows 10 shutdown after update.

Hi

I am having EXACTLY the same problem and with the same results with the troubleshooter etc. and so would love to see a cure posted here.

We appreciate you getting back to us with the added information.

The app that prevents your device from shutting down is most likely part of the updated system or could also be part of the security certificates that was installed after you performed Windows Update. We can determine which specific app is that by ending the task of the same icon in the Task Manager. However, let's try to run the System File Checker tool first to fix and correct any improper settings in your computer system. Please note of the result.

We would like to ask for the screenshot of the shut down page where it says that there's an app which prevents you from shutting down, and also the screenshot of your Task Manager under the Process tab. This is for us to have a better picture of the issue and determine the appropriate advice.

Additionally, we also suggest that you run Power troubleshooter for possible help. To do that, simply type troubleshoot in the search field or Cortana, click on it in the search result, click on Power, then click on the Run the troubleshooter button.

Any update from you is highly appreciated.

Thank you, Lawrence Lib, for your reply.

I would first of all like to repeat (for the 3rd time) that the task manager does NOT reveal the name of this mysterious anonymous app. The only app listed as running is the Task Manager itself. Attaching screen shot of this.

Thanks also for your suggestion on using the System File Checker tool. Here is the result:

Microsoft Windows [Version 10.0.16299.248]

C:\WINDOWS\system32>DISM.exe /Online /Cleanup-image /Restorehealth

Deployment Image Servicing and Management tool

Version: 10.0.16299.15

Image Version: 10.0.16299.248

[==========================100.0%==========================] The restore operation completed successfully.

The operation completed successfully.

C:\WINDOWS\system32>

Thanks also for suggesting the Power Troubleshooter. The results are here:

As for a screenshot of the Shutdown screen, you may not be aware of this but the normal manner of obtaining a screenshot ("Printscreen") does not work on a Shutdown screen. If there is another method, please let me know. In the meantime, here is a transcription of that screen:

"Closing 1 app and shutting down.

To go back and save your work,click cancel and finish what you need to do.

This app* is preventing shutdown

Shutdown anyway (clickable rectangle) Cancel (clickable rectangle)"

Neither the System File Checker tool nor the Power troubleshooter had any effect. I still have the same annoying problem.

*(As I've mentioned mentioned before, no right or left clicking or hovering reveals the named of "this app").

Hello Alan,

We would like to know the current status of the issue. Are you still experiencing the same issue when you shut down your Windows 10 device? If the issue still continues, can you tell me the current OS Build of your Windows 10 system? You can find this information by clicking the Start button, type About your PC, press Enter, and then scroll down to Windows specifications. Have you tried performing a clean boot like seahawks65 suggested? A clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you use your computer. For the steps on how to perform a clean boot, you can refer to this support article. You can also watch our YouTube video for a detailed guide.

We'll be waiting for your response.

Hi Alan, 

I had the exact same annoying problem.

I narrowed it down to a program called "Power Media Player MR"

I found it by looking in the App History of the Task Manager.

It was always the 3rd app from the top.

I uninstalled it and that annoying problem is now gone.

Thanks to you and your question in helping me solve my Mystery App preventing me from restarting and shutting down my pc properly.

Best regards

Thank you BravoCharlie 789. I did not find "Power Media Player MR" on my computer, and a search came up with similarly named apps that were available in the Microsoft store. How did you find it and how did you uninstall it? Thanks.
