What can I do if Alt + Tab is not switching applications?
If Alt + Tab is not functioning as expected, the first step is to check if your keyboard is working properly. Try using a different keyboard or testing the keys on a keyboard diagnostics tool to ensure that they are registering correctly. Additionally, restart your computer to clear any temporary issues that may be affecting your system.
If the problem persists, it may be due to a software conflict. Check for recently installed applications that could interfere with keyboard shortcuts. Uninstall or disable any suspect software and see if that resolves the issue. You can also try updating your operating system and drivers to ensure everything is up-to-date.
Why does Alt + Tab sometimes switch applications randomly?
Random application switching with Alt + Tab might happen due to a stuck key or a malfunctioning keyboard. It could also be caused by software that is inadvertently triggering the shortcut. Inspect your keyboard for any stuck keys or debris that might affect key responsiveness. Cleaning your keyboard might help resolve physical issues.
Another potential cause is background applications that take control of keyboard shortcuts. Check your running programs to identify any that might conflict. Disabling them temporarily can help determine if they are the source of the random switching. If that resolves the issue, consider uninstalling or adjusting those applications’ settings.
How can I restart the Windows Explorer process to fix Alt + Tab?
To restart the Windows Explorer process, press Ctrl + Shift + Esc to open the Task Manager. Look for “Windows Explorer” in the list of processes. Right-click on it and select “Restart.” This action will refresh the user interface and can often resolve issues related to the Alt + Tab functionality.
After restarting Windows Explorer, check if Alt + Tab works correctly. If the issue persists, you might consider a full restart of your computer to reset all processes and services. Sometimes, persistent issues require a complete restart to clear up lingering software problems.
Does Windows settings affect Alt + Tab functionality?

Certain types of malware may operate stealthily in the background, impacting how applications respond to commands. Running a thorough scan with a reputable antivirus program can help identify and remove any malware that may be present on your system.
If you suspect malware might be the cause of the problem, after completing the scan, consider performing a system restore to revert your computer to a previous, stable state. This action can help eliminate any issues introduced after malware infection, thereby restoring normal functionality to Alt + Tab.
What should I do if I recently updated my system and Alt + Tab stopped working?
If Alt + Tab stopped working after a recent system update, it is possible that the update introduced a bug or compatibility issue. In this case, the first step is to check for any additional updates, as the operating system may have released patches to correct known bugs. Check Windows Update to see if any newer patches are available for download.
If no updates help, you may want to consider rolling back the recent update. Navigate to Settings > Update & Security > Windows Update > View update history. From there, you can select “Uninstall updates” to remove the last update. This action will revert your system to a state prior to the problematic update and may restore the Alt + Tab functionality.
Can third-party software prevent Alt + Tab from working properly?
