This issue typically occurs due to pending or stuck updates, particularly related to Windows Update, where tasks like syncing settings or applying updates fail to complete. Other potential causes include unresponsive applications or services running in the background. In this article, we will discuss different ways to solve this error.

1. Close the Running Application and Perform a Shutdown

Leaving applications open during shutdown can stop Windows from closing tasks, causing the Task Host Window error. Manually closing all programs ensures no active processes delay the shutdown, allowing the system to power off smoothly.

2. Turn off Fast Startup

Fast Startup in Windows speeds up boot times by saving system data to a special file. However, it can cause issues by not allowing some background tasks to close properly during shutdown. Turning off Fast Startup allows for a complete shutdown, helping fix the “Task Host Window” error by ensuring all services and tasks close correctly.

3. Run Windows Update Troubleshooter

Using the Windows Update Troubleshooter helps fix one common cause of the Task Host Window error—stuck updates. This tool automatically finds and fixes problems with Windows Update, ensuring all tasks finish correctly and don’t block the shutdown.

4. Uninstall Windows Updates

Sometimes, new Windows updates can cause problems that lead to the Task Host Window error. Uninstalling these updates can fix the issues, allowing your computer to shut down normally again. This process returns your system to how it was before the update.

5. Clear the Software Distribution Folder

Clearing the Software Distribution folder resets the place where Windows keeps update files temporarily. If these files are damaged or incomplete, they can stop updates from finishing during shutdown. Deleting them lets Windows download new files, which often fixes the issue.

6. Use the Registry Editor

Adjusting settings in the Registry Editor can help fix shutdown delays by closing hanging processes. Changing registry values lets Windows automatically close unresponsive tasks during shutdown, removing the need to do it manually and making the shutdown process smoother. It’s important to back up the registry before making changes, to ensure you can restore files if anything goes wrong.

7. Run DISM Commands

Corrupted system files can cause shutdown problems like the “Task Host Window” error. Running DISM commands can find and fix these corrupted files, helping your Windows system work properly and shut down smoothly.

8. Turn Off Third-Party Antivirus

Third-party antivirus software can sometimes slow down shutdown by scanning or blocking important tasks. Temporarily turning off the antivirus helps the system close tasks more smoothly.
