1. Look into the Taskbar Settings.

    

Looking at the Taskbar settings is the first step toward fixing this issue. Take these actions:

2. Click the Taskbar with a right-click, then choose “Taskbar settings.”
   
   

Ensure the option to “Automatically hide the Taskbar in desktop mode” is enabled in the settings box.

In addition, if you are using a tablet or touchscreen device, ensure the “Automatically hide the taskbar in tablet mode” option is enabled.

If these parameters are enabled, the Taskbar should immediately disappear when an application is in full-screen mode. 

3. Start Windows Explorer again
   
   

Issues with Taskbar visibility are frequently resolved by restarting Windows Explorer. This is how you do it:

• • • You can launch the Task Manager by pressing Ctrl + Shift + Esc.

    • “Windows Explorer” should be located in the list of active processes.

    • Click “Windows Explorer” with a right-click, then choose “Restart.”
      
      

Restarting Windows Explorer can resolve small issues that may be causing the Taskbar to remain displayed, in addition to refreshing the desktop environment.

4. Look through the Unread Notifications
   
   

The Taskbar might remain displayed to notify you of unread alerts and crucial communications. To see if there are any notifications:

• • • On the far right side of the Taskbar, click the notification icon.

    • Examine and delete any alerts that have not yet been read.
      
      

After responding to the notifications, the Taskbar ought to disappear in full-screen mode on its own.

5. Upgrade your software and operating system.
   
   

The Taskbar remaining visible can be fixed by making sure your operating system and programs are up-to-date and compatible. To look for updates:

• • • To access the “Settings” app, press Win + I.

    • Navigate to “Update & Security” and choose “Check for updates.”

    • Install any updates available for your apps and Windows. This may fix issues and enhance full-screen mode compatibility.
      
      

6. Modify Application-Specific Preferences
   
   

Specific applications manage full-screen mode according to their settings. To find settings about Taskbar visibility and full-screen behavior, check the application’s settings or preferences. For instance, with web browsers such as Firefox or Chrome:

• • • When the browser is open, click the three-dot menu in Chrome or the three-line menu in Firefox.

    • Navigate to “Settings” and search for full-screen mode settings.

    • Make the necessary adjustments to guarantee that the Taskbar disappears correctly when the application runs in full-screen mode.
      
      

7. Turn off or remove any conflicting software.
   
   

There may occasionally be third-party software that interferes with the Taskbar’s functionality. To locate and fix this problem:

• • • Launch “Settings” and select “Apps.”

    • Look through the installed applications list and search for any programs that may be causing issues with the Taskbar.

    • After turning off or uninstalling the program, restart your machine.
      
      

You can return to the Taskbar’s typical functionality in full-screen mode by uninstalling any incompatible apps.

8. Execute a Clean Boot
   
   

By performing a clean boot, you can determine whether background services or activities keep the Taskbar visible. How to execute a clean boot:

• • • Hit Win + R, input msconfig, then hit Return.

    • Go to the “Services” tab in the System Configuration window and select “Hide all Microsoft services.”

    • Navigate to the “Startup” tab after selecting “Disable all.”

    • Select “Open Task Manager” and turn off every startup app.

    • Give your machine a restart.
      
      

Following a clean boot, if the Taskbar correctly hides in full-screen mode, you can determine which startup item or service is causing the issue and permanently stop it.
