If you are encountering the Safe Mode error while trying to play Call of Duty Modern Warfare 2 on Windows 11, it can be frustrating. This error usually prevents the game from launching normally, forcing it to start in Safe Mode, which limits functionality.

Fortunately, there are several straightforward steps you can take to fix this issue. This guide will walk you through each step in detail, helping you get back to your game without complications.

We will start with simple checks and then move on to more advanced troubleshooting if needed. By following these instructions carefully, you can resolve the error efficiently.

Let’s dive into the solutions that have helped many players overcome the Safe Mode error on Windows 11.

Quick Note: Preliminary Checks Before You Start

Before trying any fixes, make sure you have the following ready and checked:

Stable internet connection: Some game features rely on internet access, so ensure your connection is working properly.
Updated Windows 11: Check that your Windows is up to date by going to Settings > Windows Update.
Updated game client: If using Battle.net or Steam, verify the game is fully updated.
Sufficient disk space: Confirm your drive has enough free space for the game and any updates.
Administrator permissions: Run the game as an administrator to avoid permission-related issues.

Step 1: Restart Your PC and Game Launcher

Sometimes, a simple restart can clear temporary glitches causing the Safe Mode error. Follow these steps:

Close Call of Duty Modern Warfare 2 completely.
Exit your game launcher (Battle.net, Steam, or other).
Restart your computer to clear any background processes.
After restart, open the launcher and run the game again.

This step is important because temporary software conflicts often cause the Safe Mode error. Restarting resets these temporary states.

Step 2: Run the Game as Administrator

Windows 11 has strict security settings that sometimes block games from running properly. Running the game with administrator privileges can help.

Right-click on the Call of Duty Modern Warfare 2 shortcut or executable file.
Select Properties.
Go to the Compatibility tab.
Check the box for Run this program as an administrator.
Click Apply and then OK.
Launch the game again to see if the Safe Mode error is resolved.

This step ensures the game has full access to system resources, which can prevent Safe Mode triggering.

Step 3: Repair Game Files Using the Launcher

Corrupted or missing game files often cause errors. Most game launchers have a repair or scan feature to fix these automatically.

For Battle.net users:

Open the Battle.net app.
Navigate to Call of Duty Modern Warfare 2 in your game list.
Click the Options dropdown (gear icon).
Select Scan and Repair.
Click Begin Scan and wait for the process to complete.

For Steam users:

Open Steam and go to your Library.
Right-click on Call of Duty Modern Warfare 2 and select Properties.
Go to the Local Files tab.
Click Verify Integrity of Game Files.
Wait for Steam to check and fix any corrupted files.

Repairing files is essential to ensure the game runs properly without Safe Mode errors caused by file issues.

Step 4: Disable Overlays and Background Applications

Third-party overlays and background apps can interfere with the game’s normal startup. Disabling them can fix Safe Mode errors.

Close Discord, Nvidia GeForce Experience, Xbox Game Bar, and other overlay software.
Press Ctrl + Shift + Esc to open Task Manager.
Under the Processes tab, look for unnecessary apps running in the background.
Select them and click End Task to close.
Try launching the game again.

Overlays sometimes cause conflicts with game rendering or input, triggering Safe Mode startup.

Step 5: Update Your Graphics Drivers

Outdated or incompatible graphics drivers can cause game errors including Safe Mode issues. Keeping your drivers updated is crucial.

Press Win + X and select Device Manager.
Expand the Display adapters section.
Right-click on your graphics card and select Update driver.
Choose Search automatically for updated driver software.
Follow the prompts if an update is found and restart your PC.
Launch the game again.

Alternatively, visit your GPU manufacturer’s website (NVIDIA, AMD, Intel) to download the latest drivers manually.

Step 6: Adjust Launch Options or Disable Safe Mode

Sometimes the game may be forced to start in Safe Mode due to specific launch options or settings. Resetting or removing these can help.

For Battle.net users:

Open Battle.net app.
Go to Call of Duty Modern Warfare 2.
Click on Options > Game Settings.
Look for any launch options such as -safe or -safemode and remove them.
Save changes and restart the game.

For Steam users:

Open Steam and navigate to your Library.
Right-click the game and select Properties.
Under General, find Launch Options.
Remove any parameters that include -safe or similar.
Close the window and try launching the game.

This step is important because launch options can force Safe Mode even if not necessary.

Step 7: Reinstall the Game (Advanced)

If none of the above steps work, reinstalling the game can fix deeply rooted file or configuration issues.

Back up any important game data or settings if needed.
Uninstall Call of Duty Modern Warfare 2 through Control Panel or your game launcher.
Restart your computer.
Download and install the game fresh from your launcher.
Launch the game and check if the Safe Mode error is gone.

Reinstallation ensures a clean slate, removing corrupted files or settings that triggers Safe Mode.
