Solution 2. Use Windows Registry Configuration

If System Restore doesn’t work, you can tweak it with Windows Registry. Again, though, this solution can make some serious changes to your computer, use it when you are confident with commands.

The Windows Registry database contains installed programs, settings, system hardware, and more. However, Registry entries can get corrupt due to some specific files required to stack everything in place. This can happen due to viruses and malware.

So, the solution to fix the 0xc0000005 error in Windows is fixing the Registries. For that, you have to first backup the Registry as follows:

Step 1. Press Windows + R > the Run dialog box > Type Regedit.

Step 2. On the Registry Editor, locate and click on the Registry key or subkey per your desire.

Step 3. Click File > Export in the toolbar.

Step 4. On the Export Registry File dialog box, choose the location where you want to copy the Registry. Next, add a name in the File name box. And click the Save button.

Step 1. Press Windows + R to open the run dialog box and type Regedit.

Step 2. Once the Registry Editor opens, click File in the toolbar > Import.

Solution 3. Use System File Checker

A System File Checker or SFC is the best solution to scan your system for broken or corrupted files. It is a Windows built-in tool to repair incorrect, damaged, or corrupted system files.

You can run SFC commands to fix this Windows error code as follows:

Step 1. Go to the search field and look for the command prompt.

Solution 4. Check Your Boot Configuration Data

Do you have xOsload.exe, xNtKrnl.exe, or OEM-drv64.sys files on your computer? Then, they all are virus-infected files.

You can check Boot Configuration Data to ensure your PC doesn’t have infected files. To do so, you have to open Command Prompt as an admin and type BCDEdit.

After that, you need to use this command line to fix BCD content:

Del D:\Windows\System32\xOsload.exe

Del D:\Windows\System32\xNtKrnl.exe

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

ren c:\boot\bcd BCD.old

bootrec /rebuildbcd

Solution 5. Run the Windows Memory Diagnostic

If the error code 0xc0000005 constantly keeps on annoying you, the best bet is to check for a hardware defect. Specifically, damaged RAM storage can be a problem, and replacing it is the only solution.

However, before doing that, ensuring defective storage is the real problem. For this, you can use the Windows Memory Diagnostic.

When the tool opens, click on Restart now and check for problem options. This will shut down your PC and run the memory diagnostic. Once the process is complete, you will receive a message about the results. After that, you can decide whether to replace RAM or not.

Solution 6. Deactivate the AppInit_DLLs Mechanism

Another possible solution to fix the Windows 0xc0000005 error is to deactivate the AppInit_DLLs function. This function is responsible for loading DLLs in the process executed in the user mode. DLLs enable users to more effectively use the storage space.

But, sometimes, the Applnit_DLLs entry can trigger problematic access violations. So, the best thing is to deactivate this feature in the Windows Registry. Here’s how you can do that:

Step 1. Press Windows + R keys to launch the Run command box.

Step 2. Type regedit in the search field and press Enter.

Step 5. Click on OK to confirm the changes and restart your PC to check if the problem is fixed now.
