Alt Tab Not Working on Windows 7, 8 or 10 {Solved}

Keyboard shortcuts have made life easy for us while operating on the PC. However, there always has been one of the most used and maybe also one of the favorite of many users, the “ALT + TAB” combination. It is used to switch between applications while simultaneously operating multiple programs/applications.

This Alt + Tab combo is also known as the Task Switcher and has been a basic shortcut since Windows 3.0. Sometimes this combination might fail due to several reasons which can create complications in one’s computing experience. The following methods can be used to fix the issue and regain control over this useful shortcut.

How to Fix Alt Tab Not Working on Windows 7, 8 or 10

Solution 1: Turn Off The Machine and Unplug All The Cables

The simplest of all methods is to unplug the cables of the computer after shutting it down. The computer’s unresponsive behavior could be because of:

  1. The cables might be loose and hence this would create the problem of devices and equipment not functioning properly as they should.
  2. Equipment such as the keyboard tends to become unresponsive if their cable gets disconnected from the main system.

The best bet is to replug all the cables ensuring that loose wires are not causing any problems. If equipment goes bad, then the only option is to replace it. Don’t leave any stone unturned.

Solution 2: Check The Keyboard

The keyboard is the ultimate hardware present alongside a computer. This allows almost full control of the computer and can even take control of the mouse if required.  Executing shortcuts is only possible via a keyboard be it a virtual one or the real deal.

This fix basically focuses on the condition of the keyboard used to execute the shortcut.

Step 1: Check if all the keys of the keyboard are functioning properly.

Step 2: Visit this site to check your keyboard buttons:

Step 3: For offline users, open any word editing software and test the various keys individually to ensure that all the keys are working properly.

If by any chance the keyboard fails the above test, it must be replaced immediately.


Sometimes the web browser in use does not allow users to change/switch screens during operations. This might be caused due to various reasons:

  1. The browser uses plug-ins that disables the switch feature of the machine.
  2. Sometimes the Add-ons/Extensions used on these browsers do not allow switching screens in order to prevent disruption of an ongoing process.

In this case, the extensions can be removed from the setting menu itself. But a more foolproof option is to uninstall the current browser itself and use the latest versions of the browsers supported by the operating systems. One such browser is the Edge browser by Microsoft for Windows 10.

Solution 4: Restart Windows Explorer or File Explorer

The Windows Explorer or File Explorer sometimes prevents keyboard shortcuts due to the fact that it overrides the functioning of other applications. It eats away CPU memory and uses cache space for storing only its own data. This prevents switching of screens because while switching screens along with applications, the memory allocation would also change.

The following steps are valid on operating systems running on Windows XP or later versions of it.

Step 1: Open the Task Manager using one of the methods below:

Step 2: Press CTRL + SHIFT + ESC (for direct Taskbar screen)

Step 3: Press CTRL + ALT + DELETE.

Step 4: Open the Command Console by using the search bar. Type “taskmgr” and press ENTER.

Step 5: Right Click on the Window Explorer/File Explorer icon and select “End Task/Process”.

Step 6: The application can also be restarted but ending it is recommended.

Step 7: Reopen the Explorer and also try switching screens with the ALT + TAB combo between different applications.

Solution 5: Close sidebar.Exe Process

The sidebar is a vertical panel on the side on the Windows screen that contains various gadgets. This Sidebar is an exclusive that is available only to Windows 2007, Windows Vista, and Windows Server 2008 versions.

So this solution/fix is basically for the users of Windows that uses the above-mentioned versions.

Step 1: Firstly, open the Task Manager using one of the methods below:

Step 2: Secondly, press CTRL + SHIFT + ESC (for direct Taskbar screen)

Step 3: Press CTRL + ALT + DELETE.

Step 4: Open the Command Console by using the search bar. Type “taskmgr” and press ENTER.

Step 5: Under the “Processes” tab search for the “Sidebar.exe” process.

Step 6: Right Click on it and press on “End Task”.

Step 7:  Lastly, close the Task Manager and test the keyboard shortcuts required to use.

Solution 6: Disable Aero Peek

Microsoft has added a feature in Windows 7, 8, and 10 which allows viewing the desktop. This feature known as the Aero Peek is located at the extreme right side of the Taskbar. Simple placing the cursor over the aero peek button will provide a view of the desktop in use.

Solution 7: Change Registry Settings

The database for all settings used by Microsoft Windows is stored in the Registry. It stores custom as well as default configurations for all hardware devices, applications, and the whole system. Sometimes these configurations might be changed automatically to suit the requirements of the system. This may cause problems to the execution of preloaded commands such as Windows shortcuts. To solve this problem, the user needs to have administrative privileges to make changes to the Registry of the system.

Follow the given steps to solve this issue:

Step 1: Press the Windows + R to bring up the RUN

Step 4: Right-click on the window to the right of the path directory. Choose New” and then choose “DWORD (32bit) Value”.

Step 5: Create a new shortcut value of ALT + TAB by naming the value as “AltTabShortcut”. Set the value data as 1.

Step 6: Click OK and exit the editor.

Solution 13: Disconnect Hubs and Usb Headsets

A hub is a device used to connect multiple computers. Also, other network devices together through the same network port.

USB Headsets are usually combination microphones and headphones connected to the computer through a USB port/Wire.

This external hardware sometimes messes with the other existing hardware that makes them function weirdly or even cause defections. If this is the case, the user must unplug the hub and USB Headset that is currently in use with the system. This will disconnect any kind of synchronization of these devices with the other hardware and the problem should be solved easily.

Solution 14: Change Docking Station Cable Between Monitor And Notebook

People use Docking Station Cables to connect devices. This cable connects the docking station between the laptop/computer and other devices such as mobile phones, etc for providing power or to use the auxiliary features of the device connected to it.

Sometimes when the cables are defective and used for connecting the monitor and notebook, it might cause problems such as misreading information passed between the cables. This might lead to complications such as a glitch in the information received from the notebook to be misread by the computer itself.

The only solution is to change the cable itself so that the persisting problem can be solved with ease.

Solution 15: Change BIOS Version

BIOS, i.e. the basic input/output system, is the pre-written program on the computer’s memory that synchronizes the computer with its attached hardware and softwares to make the system whole and user interactive.

Follow the next steps to check the version of BIOS used on the computer:

Step 1: Search for “cmd” and open the command prompt up.

Step 2: Type the following – wmic bios get smbiosbiosversion

Step 3: Check the version of BIOS used.

If case you have out-dated BIOS version,

Step 1: Find the manufacturer of the computer’s motherboard and go to their website.

Step 2: Download the latest version of the BIOS software from the given list.

There are more complex ways to change the BIOS version of the computer through Boot-up methods but the above one is quite simple and effective in solving the inconsistency that might have been coming from an old BIOS version.

Solution 16: Change Game To Use Windowed Mode
