Introduction: Alt-Tab Agony Amidst Gaming Glory

The beauty of PC gaming lies in multitasking capabilities, with the Alt-Tab shortcut acting as a gateway between your game and other desktop tasks. However, when this quick switch results in a frozen screen, gaming joy quickly turns into tech-induced turmoil. This is especially true when you’re running Windows 11 as a lot of people have reported playing games like VALORANT and their system crashing when pressing ALT-TAB. So we will start with Windows 11 related tips.

Windows 11 Specific Tips

This issue is very common on Windows 11 based systems so try these in order (do each step then advance to the next step after testing):

    Open Regedit and go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer

    Set the name as AltTabSettings
    Double-click on the newly created AltTabSettings and change the value from 0 to 1

General Tips To Troubleshoot the Alt-Tab Issue

1. Check for Overheating

High-end games can strain your PC:

  • Ensure your PC has proper ventilation.
  • Clean out dust from fans and heatsinks.
  • Consider investing in cooling solutions if overheating persists.

2. Update Graphics Drivers

Outdated or corrupt drivers can cause compatibility issues:

  • Check your graphics card manufacturer’s website or application for the latest drivers.
  • Install any pending updates.

3. Adjust Game Settings

Tweaking in-game settings can reduce the load on your PC:

  • Switch to windowed or borderless mode.
  • Reduce graphical settings.

4. Examine Background Processes

Other software might be vying for resources:

  • Use Task Manager (Ctrl+Shift+Esc) to see active processes.
  • Close unnecessary applications, especially those consuming high CPU or memory.

5. Modify System Settings

Adjusting system visuals can aid smoother transitions:

  • Navigate to System Properties.
  • Under ‘Performance’, choose ‘Adjust for best performance’.

6. Game-Specific Fixes

Some games have known Alt-Tab issues:

  • Check online forums or the game’s official support page for patches or solutions.

7. Check for Software Conflicts

Certain applications might interfere with the Alt-Tab function during gaming:

  • Disable or uninstall software known for creating conflicts, such as screen recorders or overlay tools.


Does the game’s resolution affect Alt-Tabbing? Yes, a game running at a different resolution than your desktop can cause delays or freezes during Alt-Tabbing.

Is the issue more prevalent with certain types of games? Resource-intensive games or those running in exclusive fullscreen mode may exhibit this issue more frequently.

Should I be concerned about potential hardware damage? While frustrating, occasional freezes during Alt-Tabbing aren’t typically indicative of hardware damage. However, recurrent crashes or freezes during regular tasks might warrant further investigation.

Can virtual memory settings impact this issue? Yes. Insufficient virtual memory can lead to performance issues. Ensure your system is correctly configured for optimal performance.

Conclusion: Ensuring a Smooth Gaming Multitasking Experience

A hiccup while Alt-Tabbing during a game shouldn’t detract from the overall joy of PC gaming. By identifying the root cause and implementing targeted solutions, you can ensure a seamless transition between your game and other vital tasks.
