How to Fix 0xc0000005 Error in Windows


Windows is easily one of the most robust operating systems available, and Microsoft constantly keeps updating it with new updates.

  • The Application was Unable to Start Correctly

Commonly, the problems that cause this are:

  • Errors in the PC files
  • Issues due to a faulty RAM condition 
  • Wrong configurations or other errors in the PC settings

Fix 7: Disable AppInit_DLLs Mechanism

Another complex yet suitable solution for fixing the 0xc0000005 Error is deactivating your device’s continuously running AppInit_DLL mechanism.

In some cases, the 0xc0000005 Error Windows users notice in their system occurs due to infected or altered files due to malware or hackers. It is vital to properly evaluate the Boot Configuration Data (BCD) and resolve the issue.

How to do this?

Step 1: Open Start > Type in “cmd” in search.

Step 2: The Command Prompt app will appear in the search list. Click on the “Run as Administrator” option under it.

Step 3: Insert “BCDEdit” > Hit Enter.

Step 5: Under the Command Prompt window, run these commands:

Del D:\Windows\System32\xOsload.exe

Del D:\Windows\System32\xNtKrnl.exe

Del D:\Windows\System32\Drivers\oem-drv64.sys

attrib c:\boot\bcd -h -r -s

ren c:\boot\bcd bcd.old

bootrec /rebuildbcd

Step 6: Check again for the Error on your system after these commands run to understand if the process was successful.

Fix 9: Upgrade the Device Drivers while running Apps

This particular Windows error code can appear when one tries to access a specific app on their PC. If the prompt about the application not starting correctly, defective drivers can be the main issue. You have to update them to fix the Error.

How to do this?

Step 1: Click on the Start icon and type in Control Panel. Then, choose the first option to open.

Step 2: Press Device Manager. (In some Windows 11 devices, you can directly search for Device Manager via Start.)

Step 3: Choose the “Display Adapter” option in this menu. Click the arrow beside it.

Display Adapter

Step 4: Tap the displayed graphic card and right-click on it.

Step 5: Click on “Update Driver” from the drop-down menu.

Update Driver

Step 6: After it updates, play another video on your PC. See if the Error persists or not.
