Windows updates offer new functionality, help keep your systems secure, and tackle the incompatibility issues with some new programs. Therefore, if you’re still running an out-of-date operating system, you would more likely to encounter instability issues. To fix it, you need to download and install the latest Windows updates:

3. Update your graphics driver
Your graphics card is one of the core components of your desktop PC or laptop. And your graphics driver is essential for getting top performance from your GPU. With that said, if your graphics driver is corrupted or outdated, you would suffer from performance loss including programs not starting as expected. Therefore, to troubleshoot the issue you’re having, you need to make sure that you update your graphics driver to the latest version.
Option 1 – Manually update your graphics drivers
To update your graphics driver manually, you can go to the official website:
Then find the driver corresponding with your Windows version and download it manually. Once you’ve downloaded the correct driver for your system, double-click on the downloaded file and follow the on-screen instructions to install it.
Option 2: Automatically update your graphics driver (recommended)
If you are not familiar with computer hardware, and if you don’t have the time to update your graphics driver manually, you can, instead, do it automatically with Driver Easy.
Driver Easy will automatically recognize your system and find the correct driver for it. You don’t need to know exactly what system your computer is running or risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
Here’s how to update your drivers with Driver Easy:
1) Download and install Driver Easy.
2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
3) Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.
(This requires the Pro version which comes with full support and a 30-day money-back guarantee. You’ll be prompted to upgrade when you click Update All. If you don’t want to upgrade to the Pro version, you can also update your drivers with the FREE version. All you need to do is to download them one at a time and manually install them.)

4. Repair your game
When you’re having trouble launching the game, you need to check whether the game files are corrupted or missing. Using the built-in repair feature can help you check your game’s installation and then automatically download any replacement or missing files.
If you’re playing Modern Warfare on:
1) Open the Battle.net desktop app.
2) Click your game title. Then click on the cogwheel icon and select Scan and Repair from the list.
3) Click Begin Scan. Then you need to wait for the repair to finish.
Once done, try to launch Modern Warfare to check if it did the trick. If you’re still having the same issue, proceed to the next fix.
1) Open your Steam client.
2) Under LIBRARY, right-click your game title and select Properties.
3) Select the LOCAL FILES tab and click on the VERIFY INTEGRITY OF GAME FILES… tab.
Then Steam will verify the game’s files. This process may take several minutes. Once the process is finished, click on the PLAY button to check if you can launch Modern Warfare successfully.
5. Disable Discord overlay
Discord overlay is a pretty fancy and fun piece of tech. So many players would enable this feature. But some overlay programs, including Discord overlay, may cause Blizzard games not to launch properly. Therefore, you need to disable Discord overlay before you want to play Modern Warfare to check if it works:
1) Open up your USER SETTINGS by clicking on the cogwheel icon located on the bottom-left corner.
2) Click on the Overlay tab from the left pane. Then toggle off the button Enable in-game overlay.
After applying the changes, launch Modern Warfare to test if it did the trick.
6. Disable background applications
Sometimes, the programs running in the background can interfere with your game. To see if this is what is causing Call of Duty: Modern Warfare not launching for you, you should end those tasks.
1) On your keyboard, press the Windows logo key and R at the same time to invoke the Run box.
2) Type taskmgr, then press Enter on your keyboard.
3) Under the Processes tab, right-click on the programs that you don’t necessarily use when playing Modern Warfare and select End task.
After you’ve done these, you should be able to launch Modern Warfare.
