What Causes 0xc0000005 Error on Windows?
There are a number of known reasons causing this error to disturb the operations of various software in Windows 10. One of those reasons that are considered as a major cause is a third-party antivirus program causing conflicts with executable files and influencing their operations. One the other hand, registries can get corrupted due to malware and viruses causing the programs to behave abnormally. Sometimes, bad hardware drivers can also be the culprit causing this error.
Solutions to Fix the Windows 10 Error 0xc0000005:
Based on the reasons mentioned above, the solutions are straight-forward. So, go through the following methods to get rid of this frustrating error message.
1. Fixing the Antivirus Program
Antivirus programs can influence the executable files of a number of programs. So, in order to fix this problem, you are required to disable the third-party antivirus program to check whether it was the culprit or not. Please note that disabling antivirus programs can result in some serious threats to your computer when connected to the internet. You can also rely upon Windows’ own security software i.e. Windows Defender. It has the same functionality as of any other antivirus. You can disable antivirus by navigating to its Settings and turning the shield off.
After it is disabled, check for the error again. If, it still persists, move to the next method.
2. Fixing Registries
The registry is the central database of Windows that is constantly being used by your PC to help it read many different files & settings that it needs to run. Registries can get corrupted due to damage to some certain files required to stack everything in place. Therefore, most experts recommend that you make sure to backup your Registry and keep this backup stored on a conventional USB stick so that you may be able to revive your Registry in the previous state in case of corruption. But, if you didn’t back up your Registry, follow these steps to fix registries in order to resolve the error 0xc0000005.
- Download registry cleaner software from this link.
- After it is downloaded, install it using the recommended settings. Open the software after the installation process is finished.
- On the interface, click on the Registry tab present on the left pane and click the button labeled as Scan for Issues. It will start searching for errors in the registry and when the search will be finished, a button Fix Selected Issue will be activated. Click on that button and everything will be fixed.
3. Fixing Faulty Drivers
Drivers are the software programs that help the computer to communicate with hardware attached to it. So, when they are damaged, the hardware tends to cause glitches. Fixing these faulty divers can help you out in a number of ways. Follow the steps below.
Open the Device Manager by pressing Win + X and selecting it from the list.
Inside the Device Manager, scroll down to see if there is any hardware with a yellow mark. If there is, then, right-click over there and select Update Driver Software. If you have installed drivers recently, reinstall those drivers too.
On the window appearing after, click on Search automatically for updated driver software to let it search and install drivers automatically. In case, if, you have downloaded the drivers manually, click on the option below to browse and install them. After the process is done, check for the error.
4. Fix BCD
This method is to be carried out by the users at their own risk. This did work for some and did not for some. You will also need to re-activate Windows after performing the steps in this guide.
5. Checking for Windows Updates
Windows Updates often contain fixes for some bugs and glitches but they are also notorious for giving way to new issues on people’s computers. However, in this step, we will be checking for any updates for your Operating system because Microsoft often patches any issues that come from their updates. In order to do that, follow the guide below.
6. Restoring Computer
If you have just started getting this issue, it might be getting triggered due to a faulty driver installation or even due to a rogue application that you might’ve installed on your computer recently. Therefore, in this step, we will be reverting the state of the computer to an earlier date and hopefully, this should get our issue fixed if it was due to the above-stated reasons. In order to do this:
7. Enable Firewall
It is possible in some cases, that the error is being triggered because the application is suspicious or at least if it has been marked suspicious and the Windows Firewall isn’t running on your computer to validate this suspicious. Therefore, in this step, we will be making sure that the Windows Firewall is enabled in order to get rid of this error. For that:
8. Run SFC Scan
In some situations, you might’ve installed a bad driver on your computer or at some point, due to a storage failure, some system files or drivers might’ve been corrupted. Therefore, in this step, we will be running a complete system scan to identify any drivers that are missing signatures or to fix any abnormalities in the system files. For that:
9. Disabling Data Execution Prevention
Data Execution Prevention is a program that prevents certain programs or executables from being able to run on your computer because it suspects that they might be viruses. Due to this prevention, sometimes, as a false alarm, legit applications might also face issues while trying to run on your computer. Therefore, in this step, we will be disabling this setting from the system configuration panel. For that: If the above process is unable to fix the issue, it might be because the executable isn’t the only one being affected by the DEP program. Sometimes the DEP might actually be preventing a herd of executables from being run on the computer and to counter this we will be disabling DEP completely. Disabling DEP completely cannot be done through any Windows setting and it needs to be done manually through the command prompt. Remember to take this step as a last resort because this can in some cases makes your computer more vulnerable to viruses and malware attacks. In order to disable DEP through the command prompt:
10. Disable Firewall and Windows Defender
In some situations, the executable that you want to run on the computer might actually be blocked by the Firewall and it would not be able to make contact with its servers this way. Therefore, we will have to allow the executable in our Firewall for both public and private networks which should get it working if the Firewall is preventing it. In addition to that, sometimes the Windows Defender might prevent the application from running on your computer because its local files might be suspicious and not properly signed. This can be due to a false alarm as well so we will be disabling the Windows Defender for the application as well by adding an exclusion. In order to do that:
11. Reinstall Firefox
If you are getting this error while trying to launch Firefox, it might be occurring because the applications haven’t been installed properly on your computer. Therefore, in this step, we will be launching the app management window and uninstalling Firefox after which we will reinstall it completely by downloading it from the Firefox website. For that:
12. Scanning for Malware
It is possible in some cases that the computer has acquired malware that is preventing the user from being able to run all the system functions on their computer. Therefore, in this step, we will be using the default Windows Defender to scan our computer thoroughly for any viruses or malware that might’ve found its way on our computer. For that: Microsoft Security Scanner is an additional tool that you can use to test the system for any further viruses and malware because sometimes the default tool isn’t able to perform the scan properly. Therefore, in this step, if the issue still hasn’t been resolved, we will be using the Microsoft Security Scanner to further make sure for any issues.
13. Install Missing Drivers
It is possible in some situations that your device is missing certain drivers due to which this particular issue is being triggered on your computer. Therefore, we will be checking for any missing drivers and then we will check to see if the error is fixed. In order to do this, follow the guide below.
14. Reconfigure Registry
It is possible that in some cases, you haven’t properly configured all the registry settings or that you unknowingly configured something incorrectly. Therefore, in this step, we will be reconfiguring our Registry to fix a certain key that sometimes, if misconfigured, causes this particular error on Windows. In order to do this, follow the guide below.
15. Update Disk Drivers
In some cases, the Disk Drivers that are being used to control your Storage and other Disks installed on the computer might have been outdated due to which the error is being triggered. Therefore, in this step, we will first be opening the Device Management Window and from there, we will be updating these drivers. In order to do so, follow the steps mentioned below.
16. Disabling Automatic Updates and Uninstalling Updates
It is possible in some cases, that this error is stemming from a faulty update install. Microsoft is notorious for pushing out updates that aren’t properly customized to work for all hardware combinations and often go on to break things instead of making them better. Therefore we will make sure that the recent update isn’t installed on our computer. In order to do this, we will have to first disable automatic updates on our computer and then we will be uninstalling the recently installed updates. Make sure to back up any important data that you don’t want to lose just in case this goes bad. After stopping the computer from updating, we will now be uninstalling the recent updates that have been installed on your computer. For that: Additional Fixes:
In addition to some of the recommendations given above, you should try to check if there are any bad memory modules (RAM) installed on your computer which can be a cause of this.Also, make sure to check if you haven’t overclocked your RAM to a level beyond its recommended limit. If you have done so, try to bring it back to factory defaults and check if that fixes your issue..
