Error 0x80004001 Quick Fix Guide

Error Code 40 – What is it?

Error Code 40 is a device driver error that users encounter on any Windows 2000 and later operating systems. It occurs when the peripheral device that you connect to your PC cannot be accessed due to a change in the system registry.

This is due to the presence of invalid sub-keys of the device driver in the system registry. It is a common error that users come across and appears on your PC with either of the following messages:

“Information in the registry entry for this driver is invalid”

OR

"Windows cannot access this hardware because its service key information in the registry is missing or recorded incorrectly. (Code 40)"

Solution

Error Causes

As mentioned above, the error code is triggered when the device driver’s invalid sub-keys appear in the registry, effectively changing it. This happens when the windows system files get damaged due to the following factors:

• An incomplete program uninstallation
• An incomplete program installation
• Hardware is not removed properly
• System recovery from viruses
• An improper system shut down

Factors such as incomplete installations or uninstallations or an improper system shut down can cause files to become damaged that threaten the health of your computer.

Removing viruses from the computer is also another factor as it removes the entries in the Windows system files which contain the viruses including spyware or malware

Further Information and Manual Repair

Fixing Error Code 40 is similar to fixing other device manager error codes. Here are a few methods you can try.

Method 1 – Use System Restore

You can use system restore to eliminate the problem. Here is how you can use it:

• Log in using an Administrator account
• Click ‘Start’ button and select All Programs > Accessories > System Tools > System Restore
• Click ‘Restore my computer to an earlier time’ and click ‘Next’
• Select the last Windows restore point from the ‘On this list, click a restore point’ list, and click ‘Next’
• Click ‘Next’ on the confirmation window to proceed
• Restart your PC after restoration is complete

By restoring the system via a last saved system checkpoint, you can obtain undamaged Windows system registry files that can help avert the error code.

Method 2 – Manually uninstall then reinstall the device driver

If using system restore also does not work in removing the error code, you may have to resort to manually uninstalling and then reinstalling the device driver causing the problem.

This would be necessary since the remaining incomplete files due to a partial removal or installation of programs is what contributes to the error code. By uninstall and reinstalling the device driver program, it would lead to the completion of the files.

You can do this by firstly logging in as Administrator and open Device Manager. Select the device that is causing the problem and double click it and make sure that the peripheral is connected properly to the PC. Upon opening, click on the ‘Driver’ tab and then select ‘Update Driver’.

Make sure to refer to the system documentation that you received with your PC or computer to check for the motherboard details and driver specifics.

Method 3 – Use software to automatically download the driver

Manually uninstalling and reinstalling the driver will do the trick, however, it may be time-consuming especially when you would have to resort to your hardware user manual.

Therefore, using a program such as DriverFIX can save you a lot of time and frustration in having your device work properly on your computer.

DriverFIX, with its user-friendly approach to help you fix your PC issues, comes with an integrated database that detects which drivers you need to reconfigure within just a few seconds and downloads it automatically.

This post will guide you in fixing high CPU, Memory, and Disk usage problems caused by NTOSKRNL.exe. NTOSKRNL stands for “NT Operating System Kernel. This file is a kernel image that is responsible for a lot of systems-based processes such as Hardware Virtualization, Process, and Memory. Aside from that, it is also the one that compresses the old pages of memory that reduces the overall amount of memory being used. If you notice that your computer is running slowly and you find that the NTOSKRNL.exe file is hogging your resources such as disk usage, CPU usage as well as memory usage, then read on as this post will guide you in fixing the problem caused by NTOSKRNL.exe. Make use of the options given below to resolve the issues caused by NTOSKRNL.exe. 1] Scan your computer for potential malware There might be a good chance that your computer might be infected with malware. And this malware might be associated with the NTOSKRNL.exe file and hence making it consume a lot of system resources. So, I would really recommend you to make sure that your Antivirus is up to date and then scan your computer with it specifically the C:/Windows/System32 folder because this is the location where the NTOSKRNL.exe file is located.

Option 1 – Put your computer in a Clean Boot State

The first thing you have to do is to put your computer in a Clean Boot State as this can help you in finding any incompatible programs that are causing the problem.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Once you’ve found any incompatible programs, you need to uninstall them. Refer to the steps below to do so.

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 2 – Update or rollback drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Try to run the DISM tool

If the first two options didn’t work, then running the Deployment Imaging and Servicing Management might. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 4 – Try to stop the Runtime Broker process

The RuntimeBroker.exe or the Runtime Broker process is the one that monitors access to Windows APIs to make sure that the apps do not violate the core security of Windows. This process usually leaves a very small footprint. However, there are times when it consumes more resources than it’s supposed to and does not release memory after the work is done that results in a memory leak. As a result, it affects NTOSKRNL.exe which is why you have to stop the Runtime Broker process. To do so, refer to these steps:

• Tap the Ctrl + Shift + Esc to open the Task Manager.
• After opening Task Manager, go to the Processes tab and look for the Runtime Broker process.
• Once you find it, check if it is using more than 15% of your memory. If it is, then you most likely have an issue with an app installed on your computer.
• Select the Runtime Broker process and right-click on it and then click on the End Task option to end its process.

Option 5 – Try to run the Performance Troubleshooter

• Tap the Win + R keys to open the Run dialog box.
• Type “msdt.exe /id PerformanceDiagnostic” in the field and hit Enter to open the Performance troubleshooter.
• Then click on Next to get started. Wait until the process is completed.

Option 6 – Try using the Windows Performance Toolkit

You can also use the Windows Performance Toolkit in finding the root cause of the problem. Just refer to the following steps to use this toolkit.

• Search for “cmd” in the Cortana Search box and click on Command Prompt from the search results to open it.
• Next, type in the command given below or copy and paste it and then hit Enter:

xperf -on latency -stackwalk profile -buffersize 1024 -MaxFile 256 -FileMode Circular && timeout -1 && xperf -d cpuusage.etl

• After executing the command, wait for at least 60 seconds and then check the logs of the Windows Performance toolkit which is stored in a file named cpuusage.etl in the folder located at C:/Windows/System32. From there, you should see a list of all the causes of the System Resources being hogged.

Taking information from the internet or from other sources usually involves selecting the text, copying it into the clipboard, and then pasting it into your file. In today's modern applications pasting text will most of the time take its formating with it.

By formatting what I am talking about are parameters like font size, line breaks, hyperlinks, font styles, etc. and sometimes you do not want any of these in your file, you would like and prefer to have just plain text so you can format it as you wish.

In order to paste just plain text instead of using the CTRL + V keyboard shortcut, press CTRL + SHIFT + V instead. This shortcut will paste the only text into your file.

Shortcut and Microsoft Word

Leave it to Microsoft to make its shortcut not work in their application. In Microsoft Word, you can only use the standard CTRL + V shortcut, if you press CTRL + SHIFT + V nothing will happen. So in order to paste the only text into a word document, choose to paste special > text only

Other applications

I have tried CTRL + SHIFT + V in various applications like photoshop, illustrator, InDesign, visual studio code, slack, discord, WordPress installations, etc and only one that has not worked for me was Word and office in general so you are safe to use this trick and have desired results.

Building a custom PC is a great feeling but it can sometimes not be ideal and we are not talking about breaking or losing parts. What we mean is that choosing the right components can be sometimes a difficult task. Of course, picking a PC case can have its issues, choosing the right power supply can be tricky but pairing all components together, especially CPU and GPU can be tricky. Builders with no depth knowledge and experience can sometimes choose improper CPU or GPU, picking one of them to be much more powerful than another thus not using it to its full potential because another component cannot handle stuff at the same speed. In order to not be trumped by this kind of stuff, there is a website that is completely free and you do not even need to be registered in order to use it. Bottlenet calculator link here What is even better, once you input your components you will get advice on what to change in order to tweak the system a little more to avoid bottlenecks even more. It is a very useful tool and we are advising you to use it in order to save money but not throwing it on some component that will be half used.
