As you know, both the Windows Update and Windows Store are inter-dependable services in Windows 10 operating system. So when one of these services encounters an error like the “0x80070424, ERROR_SERVICE_DOES_NOT_EXIST”, the other service will most likely get this error as well. Note that this kind of error can occur to both the Windows Update Standalone Installer and to the Windows Update section in the Windows 10 Settings app. Some users also reported getting this error while trying to update Windows Defender as well. You can see the following error message in the Windows Update Standalone Installer:

“Installer encountered an error: 0x80070424, The specified service does not exist as an installed service.”

While you’ll see the following error message in the Windows Store:

“The were some problems installing updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070424).”

To fix this error, you can try to re-register the Background Intelligent Transfer Service DLL file or run the Windows Update and Store apps troubleshooters. You can also reset the Windows Update-related folders or the Microsoft Store or fix the Windows Update files by using the DISM tool. On the other hand, you can also use the Registry Editor or check Windows Services. For more details regarding these potential fixes, refer to each one of the given options below.

A lot of users connect to the internet are using VPN on their Windows 10 computers which means that their regions could be different from the actual region of their Windows 10 computers. Thus, if you are facing some issues in updating your computer in this kind of environment, specifically the Windows Update error 0x800F0922, you need to follow the tips given in this guide to help you resolve the issue. When you encounter this kind of Windows Update error, you might see either of the following error messages on your screen:

“Windows could not search for updates, Code 0x800F0922 Windows Update encountered an unknown error” Or: “Windows failed to install the update with error 0x800F0922”

This issue might be caused by two possible reasons such as:

1. VPN issues
2. Not enough space on the System Reserved partition

To resolve the problem, here are some tips that might help:

Option 1 – Try disabling the VPN

As mentioned, if you are using VPN, this could be the reason why you’re getting the Windows Update error 0x800F0922 so the most obvious thing to do is for you to turn off the VPN and try to run the Windows Update once more. And if you use a VPN software that works using their software, you can just completely exit or log-off from its account. On the other hand, if you are using a built-in Windows 10 VPN, you can simply turn it off or delete all the settings you have created there. Although it’s understandable that you might have to use a VPN connection to connect to the work network, you really have to disable it at least until the Windows Update is no longer stuck in the error 0x800F0922. It would be best if you do this when you are not working.

Option 2 – Try to free up space in the System Reserved partition

The System Reserved partition is a part of the hard disk created when Windows is first installed on it. It is where the Boot Configuration Database, Boot Manager Code, Windows Recovery Environment, and the reserves space for the startup files are stored. And as mentioned early on, the error might be due to some insufficient space in the System Reserved partition so the next thing you can do is to increase the space in this partition. Note that it is a complex process so you need to make sure that you have made backups to all your data on the computer. So if ever something goes out of hand, at least you have copies of your important files in case you aren’t able to boot into the system at all.

So you have just got home from that new computer store with your fancy and all-new mouse, screen, keyboard, etc. You plugged in your new component, Windows detected it, installed drivers for it and it is working like a charm. A few months later down the road and the computer starts little by little to slow down. Plug and play is a great concept, and automatic detection is even greater but how time passes old unused stuff piles in your hard drive and in Windows itself thus slowing down your computer and taxing it more and more as new components and software are added. Old drivers from old components sadly are not removed from Windows itself and over some larger period of time they can pile up and slow down your daily operations on the computer or even cause some problems in it. This guide will teach you how to manually remove old unused device drivers from your Windows so it is fresh and like new again.

Making old devices visible

In order for us to remove old drivers, the first thing we must do is make them visible in our device manager, old drivers are hidden and will not show up, we must make this happen. We do this by pressing WINDOWS + X keys on your keyboard to bring up a hidden menu in Windows. Once the menu appears, click on Command Prompt (admin) Once the command prompt with administrator privileges comes on-screen type in it following string: The device manager will open, go to view > snow hidden devices in order to show unused devices.

Removing old device

Open any category and if there is a device that was once used and still has its drivers in the system it will be shown as faded out. Right-click on the device and click on uninstall device to remove it completely from your system. Please always be careful when removing devices so you do not remove the device which is being used by mistake and always double-check that you are removing something that you used to have on your system. This method will show all hidden devices even ones that are hidden but crucial to the system working properly.

A lot of Windows 10 users have reported recently that their computers are frequently crashing with a Blue Screen error with an error code “VIDEO_DXGKRNL_FATAL_ERROR”. This kind of Stop error appears not so often and its bug check value of 0x00000113 is an indication that there is some violation in the Microsoft DirectX graphics kernel subsystem. This error also occurs when there is a corrupted driver that interferes with the GPU’s normal functionality. According to some security experts, this kind of error is reported to only occur in Windows 10 PCs. Users started getting this error right after a large Windows Update. The cause of this error might have something to do with a violation in the DirectX graphics kernel subsystem where there could be a bad DirectX install or some corrupted Dynamic Link Library or DLL. Aside from that, the error might also be caused by the Nvidia driver which might have crashed or it could also be that there is an intermittent power supply. Moreover, an outdated BIOS as well as a third-party security program might be the ones behind this Blue Screen error. Whichever the case may be, you need to fix the VIDEO_DXGKRNL_FATAL_ERROR BSOD error by following the instructions given below carefully.

Option 1 – Try checking if the NVIDIA graphics card is enabled and update it as well

Although the problem is quite massive, the fix could be as simple as enabling the NVIDIA graphics card if it turns out to be disabled.

Option 2 – Update or uninstall third-party security program

As mentioned, the VIDEO_DXGKRNL_FATAL_ERROR Blue Screen error might be caused by a third-party security program that’s installed on your computer. So you have to either update it or uninstall it to resolve the issue.

Option 3 – Check the power supply for any inconsistency

The Blue Screen error might also be caused by an intermittent power supply. If there is any intermittent changes between the main supply and the battery power, it might lead to bad contact on your supply to the charger and thus, causes the VIDEO_DXGKRNL_FATAL_ERROR Stop error to appear. So to check if this scenario is applicable to you, you have to monitor your computer for any frequent changes between the power supply and the battery power. If you see that the supply is displaying power On and Off, see if the same goes when the power supply is disconnected. However, if it does not occur, you might have to purchase a new power adapter cable and replace the one that you have right now.

Option 4 – Reinstall the Graphics card drivers

• Tap Win + R to open Run then type “devmgmt.msc” in the field and hit Enter to open the Device Manager.

System Interrupts are operating system processes that function as an alert system for the CPU. So whenever a scenario needs the attention of the CPU, it alerts the CPU about it. In turn, the CPU suspends what it is doing, saves it, and then takes care of that important job and once that job is completed, it resumes back to what it was doing. This indicates that although System Interrupts appears as a process, it’s actually not. As a matter of fact, it is like a manager that reports to the CPU about all interrupts that happen on a hardware level, e.g. hardware interrupts. And if there are lots of interrupts, this means that there might be various errors occurring on a hardware level. As a result, it may take a lot of system resources. And if you consider disabling System Interrupts, stop right there as your computer will almost become useless without it. So if you see System Interrupts consuming high CPU usage in your Windows 10 computer, you can fix it without having to disable it and cause more problems. If System Interrupts takes up more than 5 to 10% of CPU, then you definitely have a problem. This could be happening due to some hardware or driver issue. The first thing you can do is to try rebooting your computer once and see if the issue comes back or not. High CPU usage of System Interrupts is a huge backlog for the CPU and it stays in the loop. If a simple system restart didn’t fix this issue, here are some suggestions you can try.

Option 1 – Try to update the hardware drivers

As stated, the problem might have something to do with hardware drivers so you can try to update these drivers and see if it works.

• Reboot your computer into Safe Mode with networking support.
• Tap the Win + R keys on your keyboard to open the Run dialog box.
• After that, type “devmgmt.msc” in the field and hit Enter or click OK to open the Device Manager.
• After opening the Device Manager, update all the outdated Hardware drivers on your computer.
• Next, right-click on all the driver entries that are appropriately labeled, and then click the Update driver option.
• Now restart your PC and check if the BSOD error is fixed or not.

Note: On the other hand, if a recent update has caused the System Interrupts high CPU usage, then you might want to roll back your hardware drivers to their previous versions. You can check with the Windows Update History to check out any recent updates as well as the previous ones.

Option 2 – Try to disconnect and reconnect all hardware and cables

A lot of users reported that they were able to fix the problem by disconnecting and reconnecting cables and hardware like scanners, printers, cameras can help in fixing the problem. In addition, you can also boot your computer in a Clean Boot State so that you can find the problematic hardware by hit and trial method. Refer to the steps below to do so:

• 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.)

Option 3 – Try to enable or disable Hardware

If you do not want to remove hardware, you can just disable them using the Device Manager. Note that this can also be applied to the internal hardware.

• Tap the Win + X + M keys to open the Device Manager.
• Next, navigate to the device you want to disable.
• Then right-click on it and choose to disable the device.

Note: Make sure that you disable one device at a time and then give it a couple of minutes and check if there are any changes in the CPU usage to pinpoint the hardware. And if there is no change, you need to enable the device you’ve just disabled and then proceed to disable the next hardware device. If there are changes, then it’s probably the culprit. Just keep in mind that you must no disable any device that is needed to keep your system up and running.

Option 4 – Try to update the BIOS/UEFI

Updating the BIOS/UEFI can help you fix the high CPU usage of System Interrupts but as you know, BIOS is a sensitive part of a computer. Even though it is a software component, the functioning of the hardware depends on it largely. Thus, you must be careful when modifying something in the BIOS. So if you don’t know much about it, it’s best if you skip on this option and try the other ones instead. However, if you are well-versed in navigating the BIOS, then follow the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Next, type “msinfo32” in the field and press Enter to open System Information.
• From there, you should find a search field on the bottom where you have to search for the BIOS version and then press Enter.
• After that, you should see the developer and version of the BIOS installed on your PC.
• Go to your manufacturer’s website and then download the latest version of BIOS on your computer.
• If you are using a laptop, make sure that you keep it plugged in until you have updated the BIOS.
• Now double click on the downloaded file and install the new BIOS version on your computer.
• Restart your computer to apply the changes made.

Option 5 – Run the Hardware and Devices Troubleshooter or the Performance Troubleshooter

Hardware and Devices Troubleshooter:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Performance Troubleshooter:

• Tap the Win + R keys to open the Run dialog box.
• Type “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.
