Hello,

“Task Host Window” manages the applications running on your PC and is responsible for closing them properly during shutdown.

This message appears when Windows cannot close one or more applications correctly.

Normally, Windows will complete the shutdown process on its own, so waiting for a short time should allow it to shut down.

Does it still fail to shut down even after waiting for a while?

Possible causes include:

Known issues caused by Windows Update

Third‑party applications, or updates in progress for Windows Update or Microsoft Store apps

Unsaved files that are still open

Applications that continue running in the background even after clicking the X to close them

Background applications that are registered as startup apps and remain active

Please try the following steps:

Perform a full shutdown

On the desktop or sign‑in screen, hold down the Shift key on your keyboard and click Shut down.

This does not bypass Fast Startup; instead, it temporarily disables Fast Startup for this one shutdown only, allowing Windows to fully close all tasks.

Clean boot

This helps determine whether a background application is causing the issue.

Please refer to the following support article for the steps:
How to perform a clean boot in Windows

    Please try these steps:

    Open Registry Editor using regedit command.

    Go to HKEY_CURRENT_USER\Control Panel\Desktop.

    Create a string value in right pane, name it as AutoEndTasks and set it to 1.

    Close Registry Editor, restart system.

    Let us know if this helps!

    P.S. If you're new to registry, create System Restore point before try the steps.

    AI just told me to do what I do now, which is to click shut down anyway. But that is not fixing the problem.
