Not only does it save you time but also your effort in moving the mouse.
However, it may fail to register at times, preventing you from switching windows.
Often, this problem is a hardware issue, but software problems can also cause this to occur.
If you also experience the same problem, here are some fixes you’re able to try.
Rule Out Hardware Issues
It is important to rule out hardware issues at the beginning of the troubleshooting process.
If one of the Alt keys isn’t working, try using another working Alt key.
If the other Alt key does not help, continue with the rest of the fixes.
Thus, it’s imperative to reinstall the keyboard driver on the system.
Check whether reinstalling the keyboard driver had any effect?
Continue applying the other fixes if not.
Therefore, non-responsiveness on the Windows Explorer side can also be to blame for the shortcut not registering.
Restart Windows Explorer to rule this possibility out.
If not, continue with the remaining fixes.
Enable Peek Option
Occasionally, Alt-Tab fails to register when the Peek option has been disabled in Windows options.
Hence, ensure that isn’t the case here by enabling Peek in Windows configs.
If you’re still having trouble, move on to the next fix.
If yes, you should uninstall the software.
you could also use this fix the other way around.
Alt-Tab may function properly with the Alt-Tab terminator installed, making it the best solution.
Modify Registry
If all else fails, modifying the Registry should be your last resort.
Therefore, if you are not familiar with tweaking registry options, skip this step.
However, avoid changing any other registry configs to prevent causing more trouble.
Alt-Tab Still Isn’t Working?
Hopefully, applying the fixes in the list will get the Alt-Tab shortcut working again.
If it still does not work, try applying some other general fixes.
