How to Fix Call of Duty Warzone Not Working on Windows 11: Step-by-Step Solutions

Call of Duty Warzone is one of the most popular battle royale games out there. However, sometimes it may not work properly on Windows 11. This can be frustrating, especially when you just want to jump into the game and play.

Fortunately, many common issues with Warzone can be fixed with some simple troubleshooting steps. You don’t need to be a tech expert to follow these solutions.

In this guide, we will walk you through easy and detailed fixes to get your game up and running again. Let’s get started.

By following these steps carefully, you can solve most problems that prevent Warzone from launching or running smoothly on your Windows 11 PC.

Quick Note: Preliminary Checks Before Troubleshooting

Check system requirements: Ensure your PC meets the minimum specs for Warzone. Windows 11 should be updated to the latest version.
Stable internet connection: Warzone requires a good internet connection. Make sure your network is working without interruptions.
Close background apps: Some programs running in the background can interfere with Warzone. Close unnecessary apps to free up resources.
Update graphics drivers: Outdated drivers often cause game crashes or failures to launch. Keep your GPU drivers current.

Step 1: Restart Your PC

Before trying anything complicated, simply restart your computer. This clears temporary glitches and frees up system resources. Many times, a fresh reboot can fix minor software conflicts that stop Warzone from working.

Step 2: Run Warzone as Administrator

Running the game with administrator privileges allows it to access all necessary files and system permissions. Here’s how:

Right-click the Warzone shortcut or executable file.
Select Properties from the context menu.
Go to the Compatibility tab.
Check the box that says Run this program as an administrator.
Click Apply and then OK.
Try launching the game again.

This step helps if Warzone was blocked from accessing necessary files or network features.

Step 3: Update Windows 11 and Graphics Drivers

Keeping your system and drivers updated ensures compatibility with the latest game updates and fixes bugs.

Update Windows 11:

Click the Start menu and open Settings.
Go to Windows Update.
Click Check for updates.
Install any available updates and restart if prompted.

Update Graphics Drivers:

Depending on your GPU (NVIDIA, AMD, or Intel), visit the official website or use their update software to download the latest drivers.

Step 4: Repair Game Files Through Battle.net

Corrupted or missing game files can prevent Warzone from launching. Battle.net offers a repair tool that checks and fixes these files.

Open the Battle.net launcher.
Select Call of Duty: Warzone from your games list.
Click the Options dropdown (gear icon).
Select Scan and Repair.
Click Begin Scan and wait for the process to finish.
Try launching the game again.

This process ensures all the game files are intact and correctly installed.

Step 5: Adjust Firewall and Antivirus Settings

Sometimes, your firewall or antivirus software may block Warzone from connecting to the servers or running properly.

Temporarily disable your antivirus and firewall.
Try launching Warzone.
If the game works, add Warzone and Battle.net as exceptions in your antivirus and firewall settings.
Re-enable your security software afterward.

Adding exceptions prevents your security programs from mistakenly blocking game files or network connections.

Step 6: Disable Fullscreen Optimizations

Windows 11’s fullscreen optimization feature can sometimes cause performance issues with games.

Right-click the Warzone executable file.
Select Properties.
Go to the Compatibility tab.
Check the box for Disable fullscreen optimizations.
Click Apply and then OK.
Launch the game again.

This tweak can improve game stability and reduce crashes.

Step 7: Reinstall Call of Duty Warzone

If none of the above steps work, reinstalling the game can fix deeper issues with the installation.

Open the Battle.net launcher.
Select Warzone and click Uninstall.
Once uninstalled, restart your PC.
Reinstall Warzone through Battle.net.
Launch the game and check if it works.

This is a last-resort fix but often resolves stubborn problems.
