Introduction

In this tutorial, we will explore three effective methods to fix issues with the Taskbar or Start Menu not working in Windows 11. This guide is designed for users who are experiencing problems where the Taskbar is unresponsive or the Start Menu is freezing. Follow the steps below to troubleshoot and resolve these issues.

Step 1: Restart Windows Explorer

Restarting Windows Explorer can refresh the Taskbar and resolve many issues.

1. Press Ctrl + Shift + Esc to open the Task Manager.
2. In the Task Manager window, locate Windows Explorer in the list of processes.
3. Right-click on Windows Explorer and select Restart.
4. Wait a moment for Windows Explorer to restart and check if the Taskbar or Start Menu is functioning properly.

Tip: This method is quick and often resolves temporary glitches without needing a full system restart.

Step 2: Run System File Checker

Using the System File Checker tool can help repair missing or corrupted system files that may be causing issues.

1. Press Windows + S to open the search bar.
2. Type cmd, right-click on Command Prompt, and select Run as administrator.
3. In the Command Prompt window, enter the following command:

   sfc /scannow
   

4. Press Enter and wait for the scan to complete. This process may take some time.
5. Once finished, restart your computer and check if the Taskbar or Start Menu is working.

Common Pitfall: Ensure you run the Command Prompt as an administrator to avoid permission issues.

Step 3: Delete the IrisService Registry Key

If the previous methods do not work, you can delete the IrisService registry key, which may be causing the problem.

1. Press Windows + R to open the Run dialog.

2. Type regedit and press Enter to open the Registry Editor.

3. Navigate to the following path:

   HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\IrisService
   

4. Right-click on the IrisService key and select Delete.

5. Close the Registry Editor.

6. To apply the changes, open the Command Prompt as an administrator again and enter the following command:

   reg delete HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\IrisService /f && shutdown -r -t 0
   

7. Press Enter. Your computer will restart immediately.

Warning: Be careful when editing the registry, as incorrect changes can lead to system instability. Always back up the registry before making changes.
