What is Windows 11 Application Error 0xc0000005?
The error 0xc0000005 is a broad Windows error known as an “Access Violation.” It occurs when an application attempts to access a memory location that it is not authorized to reach.
When this happens in Windows 11, the software usually terminates immediately. You will experience a “Crash to Desktop” (CTD) without much warning. This can be caused by faulty hardware, corrupt registry entries, or incompatible drivers.
It is one of the most common errors for gamers and power users. Understanding whether the issue is software-based or hardware-based is the first step toward a permanent fix.
Step-by-Step Solutions to Fix Error 0xc0000005
1. Run SFC and DISM Commands
System file corruption is a leading cause of memory access errors. Windows includes built-in tools to repair these files automatically.
Open Command Prompt as Administrator and run the System File Checker:
sfc /scannow
After the scan finishes, run the Deployment Image Servicing and Management (DISM) tool to repair the system image:
DISM /Online /Cleanup-Image /RestoreHealth
2. Disable Data Execution Prevention (DEP)
DEP is a security feature that protects your system from viruses. However, it can sometimes block legitimate applications, triggering the 0xc0000005 error.
To exclude a specific app from DEP:
1. Open **Settings** and search for “View advanced system settings.”
2. Under the **Advanced** tab, click **Settings** in the Performance section.
3. Go to the **Data Execution Prevention** tab.
4. Select “Turn on DEP for all programs and services except those I select.”
5. Click **Add** and locate the .exe file of the crashing application.
3. Update Your Graphics Drivers
Outdated or corrupt GPU drivers often conflict with memory allocation in Windows 11. This is especially true for video games and creative software.
Download the latest drivers directly from the manufacturer (NVIDIA, AMD, or Intel). Perform a “Clean Installation” if the installer provides that option to ensure no old files remain.
4. Check for RAM Issues
Since 0xc0000005 is a memory violation error, faulty RAM sticks are often the culprit. You can use the Windows Memory Diagnostic tool to check for hardware failure.
Press **Win + R**, type the following command, and press Enter:
mdsched.exe
Choose “Restart now and check for problems.” Your PC will reboot into a diagnostic environment.
5. Repair or Reset the Application
If the error only occurs with one specific app, the installation files for that app might be damaged.
1. Go to **Settings > Apps > Installed Apps**.
2. Find the problematic application and click the three dots (…).
3. Select **Advanced options**.
4. Click **Repair**. If that doesn’t work, click **Reset**.
