World of Warcraft (WoW) is a popular game enjoyed by millions. However, sometimes players encounter errors that disrupt their gaming experience. One such issue is Error 134, which can be frustrating to handle.

This error often causes the game to crash unexpectedly. It usually relates to memory or hardware problems but can also be caused by software conflicts. Fortunately, there are several simple steps you can try to fix it on Windows 11.

The following guide will walk you through clear troubleshooting methods. Each step is designed to be easy to understand and follow, even if you’re not very tech-savvy.

By the end, you should have a better idea of what causes Error 134 and how to resolve it effectively.

Quick Note Before You Begin

• Check your system specs: Ensure your PC meets the minimum requirements for WoW and Windows 11.
• Update Windows: Most issues are fixed by having the latest system updates installed.
• Close background apps: Running many programs simultaneously can cause conflicts or memory overload.
• Backup important data: Before making major changes, it’s good to save your important files.

Step 1: Restart Your Computer

This might sound obvious, but restarting your PC can resolve temporary glitches. When you reboot, the system clears memory and stops unnecessary processes that might interfere with WoW.

To restart, click the Start menu, select the Power icon, and then choose “Restart.” After your PC powers back on, try launching the game again.

Step 2: Update Your Graphics Drivers

Graphics drivers are software that help your operating system communicate with your video card. Outdated or corrupted drivers can cause crashes like Error 134.

To update your drivers on Windows 11:

1. Press Win + X and select Device Manager.
2. Expand the Display adapters section.
3. Right-click your graphics card and select Update driver.
4. Choose Search automatically for drivers and follow the prompts.

If Windows doesn’t find a new driver, visit the manufacturer’s website (NVIDIA, AMD, or Intel) to download the latest version manually.

Step 3: Run WoW as Administrator

Sometimes, WoW needs special permissions to access certain files or hardware. Running the game as an administrator can help avoid permission-related crashes.

To do this:

1. Right-click the WoW shortcut or executable file.
2. Select Properties.
3. Go to the Compatibility tab.
4. Check the box for Run this program as an administrator.
5. Click Apply and then OK.

Try launching the game again to see if the error persists.

Step 4: Repair Game Files with Battle.net

Corrupted or missing game files often cause crashes. Battle.net has a built-in repair tool that scans and fixes these files.

Here’s how to use it:

1. Open the Battle.net desktop app.
2. Select World of Warcraft from the list of games.
3. Click Options (gear icon) next to the Play button.
4. Choose Scan and Repair.
5. Click Begin Scan and wait until the process finishes.

Once done, try running WoW again.

Step 5: Disable Overclocking and Adjust Power Settings

Overclocking your CPU or GPU can cause instability, leading to Error 134. Similarly, certain power settings might limit hardware performance.

To disable overclocking, enter your BIOS/UEFI settings during startup (usually by pressing Delete or F2) and reset to default clock speeds.

To adjust power settings in Windows 11:

1. Open Settings via the Start menu.
2. Go to System > Power & battery.
3. Under Power mode, select Best performance.

These steps ensure your hardware runs stably during gaming.

Step 6: Check for Software Conflicts

Some antivirus programs or third-party apps can interfere with WoW and cause crashes. Temporarily disable your antivirus or any background apps like screen recorders, overlays, or VPNs.

Make sure to re-enable your antivirus after testing to keep your system protected.

Step 7: Increase Virtual Memory (Paging File)

Virtual memory helps your PC handle heavy workloads by using disk space as temporary RAM. Insufficient virtual memory can cause crashes during gaming.

To increase virtual memory:

1. Press Win + S and type Advanced system settings, then open it.
2. Under the Advanced tab, click Settings in the Performance section.
3. Go to the Advanced tab again and click Change under Virtual memory.
4. Uncheck Automatically manage paging file size for all drives.
5. Select your system drive (usually C:).
6. Choose Custom size and enter values. For example, set Initial size and Maximum size to 1.5 times your RAM size in MB.
7. Click Set, then OK to apply.

Restart your computer and try WoW again.

Step 8: Reinstall World of Warcraft

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

To reinstall:

1. Open Battle.net and go to the WoW page.
2. Click Options and select Uninstall Game.
3. After uninstalling, download and install WoW again using Battle.net.

This ensures a clean installation of the game files.
