Once we use our computer, we always run several applications or documents at once. Use the Alt + Tab key combination to switch between two frequently used applications or documents that have been modified in Windows.

However, if you press Alt + Tab, Windows will not display anything or show any open applications or documents for a second or two and then disappear. This means that “Alt Tab does not work”.

You may be wondering why this problem occurs. There are several reasons for this problem, for example: B. keyboard, wrong system settings, conflict between files, etc.

Now let’s see how to fix the “Alt Tab does not work” problem. Here, I recommend first to turn off the device and run all cables. Then wait a few minutes, reconnect all the cables and switch on the device and the monitor. Finally, check if “Alt Tab Not Working” is fixed. If not, try the following options.

Make sure it is not your keyboard.

First of all, you need to make sure that your keyboard works correctly and is not damaged. Keys are fragile and can break or press incorrectly if something happens to them.

You can make sure that your Alt and Tab keys are working by going to a website that will automatically detect and display the keys you have pressed. We recommend that you use Key-Test.

The tester cannot distinguish between double keys like Alt. Be sure to check both and make sure that the on-screen keyboard highlights the Alt key when you press it!

If the Alt and Tab keys work correctly, the on-screen keyboard should look like this. Can you see that either key is glowing? This indicates that there is something wrong with your keyboard. Clean it or check if Alt-Tab is working with another keyboard.

Make sure you have enabled the App Switching feature

The Alt + Tab key combination for switching between different applications is enabled by default in Windows 10. However, if you use multiple monitors, you will need to make minor changes.

  • So, open “Settings”, click “System”, then select “Multitasking” in the right pane.
  • At the bottom of the screen, press Alt + Tab. This will display the open windows. Select the option you want.
