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.

Option 1 – Try to re-register the Background Intelligent Transfer Service DLL file

You may have to re-register the Background Intelligent Transfer Service DLL file using the regsvr32.exe before you can successfully install the program and fix ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and un-register OLE controls as DLL and ActiveX (OCX) controls in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
  • regsvr32 Qmgr.dll /s
  • regsvr32 Qmgrprxy.dll /s

Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.

• After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully.
• Now restart your computer and check if the error is now fixed.

Option 2 – Try to run the Windows Store or the Windows Update Troubleshooters

The Windows 10 Store Apps Troubleshooter will help you in fixing the Error code 0x80070424. This is a great built-in tool from Microsoft that helps users fix any app installation issues. So this is worth a try to solve the problem. This built-in tool also helps you fix the Windows 10 Store if it isn’t working. To use the Windows Store Troubleshooter, follow the steps below.

• Tap Win + I keys again to open the Windows Settings panel.
• Go to Update & Security and then go to Troubleshoot.
• On your right hand side, scroll down to find the Windows Store Apps and then click on Run the troubleshooter option and see if it fixes the problem.

Note: You can also try running the Windows Update troubleshooter to fix the error. You can run it under the Windows Update section of Update & Security.

Option 3 – Delete the files from Software Distribution Folder & Catroot2 folders

The downloaded Windows Updates are placed in a folder called “SoftwareDistribution”. The files downloaded in this folder are automatically deleted once the installation is completed. However, if the files are not clean up or if the installation is still pending, you can delete all the files in this folder after you pause the Windows Update service. For complete instructions, refer to these steps.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic and the MSI Installer
• Next, got to the C:WindowsSoftwareDistribution folder and get rid of all the folders and files there by tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer and then try to run Windows Update once more.

Option 4 – Try to reset the Microsoft Store cache

Just like browsers, Microsoft Store also caches as you view apps and games so it is most likely that the cache is no longer valid and must be removed. To do so, follow the steps below.

• Right click on the start button and click on Command Prompt (administrator).
• Next, type in the command, “wsreset.exe” and tap Enter. Once you do, the command will clear the cache for the Windows Store app.
• Now restart your PC and afterwards, try opening Microsoft Store again and then see if Error Code 0x80070424 is resolved or not.

Option 5 – Try to check the Windows Update or WU setting in the Registry

• Tap the Win + R keys to open the Run utility and type “regedit” in the field and tap Enter to open the Registry Editor.
• Next, go to this registry path: ComputerHKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsWindowsUpdate
• Here, look for the DWORD named “DisableWindowsUpdateAccess” and double click on it and then set its value data to “0”.
• Exit the Registry Editor once you’re done and restart your computer.

Option 6 – Try to check the status of some Windows Update Services

• Tap the Win + R keys to open the Run dialog box.
• Next, type “services.msc” in the field and hit Enter or click OK to open Services.
• From the list of Services, look for the following services and make sure that their Startup type is as follows:
  • Windows Update Service – Manual (Triggered)
  • Background Intelligent Transfer Service – Manual
  • Workstation Service – Automatic
• After that, check if the Service status of the listed services above are set to Running. If they’re not, click on the Start button to start these services and then check if you can now enable the Windows Update service or not.

Option 7 – Run the DISM tool

You can also run the Deployment Imaging and Servicing Management or DISM tool to fix the error code 0x80070424. 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.
• Once it’s done, reboot your computer and check if it has fixed the error.

If you are trying to run Windows Upgrade on your Windows 10 computer but suddenly interrupted by the error 0x800F081E – 0x20003, worry not for this post will guide you on how you can fix this Windows Upgrade error. This particular Windows Upgrade error is a Windows status code for CBS_E_NOT_APPLICABLE which indicates that some of the update requirements are missing or the files that are installed are already of a higher version compared to the ones that are still pending. In most cases, this error occurs when you try to upgrade to earlier versions of the Windows 10 N edition to a later version. Here’s the full content of the error message:

“0x800f081E-0x20003, The installation failed in the SECOND_BOOT phase with an error during BOOT operation”

In case you don’t know, Microsoft distributes special “N” editions of Windows in Europe and the “KN” editions in Korea. These editions are the same as the standard editions of Windows except that they do not have the Windows Media Player as well as the multimedia playback features. Thus, when the Windows Upgrade fails with the error code and error message and it doesn’t provide much information as to why the update couldn’t be installed, there is something you can do about it to fix the error. Since Windows uses generic error codes and so if you see the error code 0x800f081e, you have to check the error log first. For more details, follow the instructions laid out below. Step_1: You need to navigate to C:$WINDOWS.~BTSourcesPanther and from there look for the text file named “setuperr.log” and open it with a text viewer/editor program like Notepad. Step_2: After opening the setuperr.log file, you should see content that’s similar to this:

C:WINDOWSSoftwareDistributionDownload80b2677d6e15a2a206625bb25a7124feamd64_Microsoft-Windows-MediaPlayer-Package~~AMD64~~10.0.17134.1. Error: 0x800F081E 2019-09-10 20:26:57, Error SP Operation failed: Add [1] package C:WINDOWSSoftwareDistributionDownload80b2677d6e15a2a206625bb25a7124feamd64_Microsoft-Windows-MediaPlayer-Package~~AMD64~~10.0.17134.1. Error: 0x800F081E[gle=0x000000b7]

Note: From the content above, it is clear that the Windows Upgrade failed due to complete due to the Windows Media Player. It could be that the log file may contain other error messages and other error codes and if you see the error code 0x800f081e from the list, then you need to uninstall the Media Feature Pack. Step_3: You have to uninstall the Media Feature Pack.

• Tap the Win + R keys to launch the Run dialog box and type “optionalfeatures.exe” in the field and hit Enter to open the Windows Features wizard.
• Next, you need to wait until the list of Windows Features populates and then click on the + sign to collapse the folder of the Media Features.
• After that, uncheck the “Windows Media Player” option from the Media Features folder.
• Now click on the Yes and OK buttons to save the changes made and then close the Windows Features dialog box.
• Restart your computer and boot, try to run the Windows Upgrade process again, and check if the error is fixed or not.

Note: If the installation has been successfully completed, you have to go back to the Windows Features and enable the Windows Media Player again. And if you are using the Windows 10 N Edition, then you can just download and install the latest version of the Media Feature Pack for your Windows 10 N edition. On the other hand, running the built-in Windows Update troubleshooter could also help you resolve any Windows Update-related problems, including the error 0x800F081E – 0x20003. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button.

Windows defender error 0x800700AA, service can not be started comes when the user is trying to run Windows defender scan on their system. This kind of behavior happens for two reasons mostly, third-party application conflict or corrupted system files. In this article, we will tackle both scenarios and provide you with solutions in both cases.

Use third party automatic solution

If you are not tech-savvy or you do not wish to manually tackle with Windows system you can use RESTORO (guide and download link below) to automatically repair this error. RESTORO will automatically scan your system and fix all errors with just a single click of a mouse. If you wish to fix the error manually keep on reading.

Third-party application conflict

In this rare scenario when Windows defender can not start scan due to conflict with installed service or application in the system solution is quite simple. Restart your PC into safe mode and run the scan from there. In a safe mode environment, minimum drivers and services are only loaded eliminating any conflicts that might occur when everything is booted. If Windows defender can not run the scan in safe mode and you get the same 0x800700AA error then you can eliminate application conflict as a reason and move to the next solution which will tackle corrupted system files. If you, however, managed to run a scan then you have a rare third-party application conflict, you can boot normally into windows and try to eliminate one by one to see which one is causing the issue. The safest bet would be to start with security software because most of the time that is what causes conflicts in running services and applications.

Corrupted system files

If the previous solution has not provided you with results then you have system file corruption that needs to be fixed. Move from one solution to another as presented below:

1. Run SFC scan

   SFC scan is a built-in Windows tool for solving corrupted system files issues, it is fully automated and does not require from the user any kind of knowledge or information. To run it and scan the system do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) In command prompt type SFC /SCANNOW and press ENTER Wait for the process to finish, do not interrupt it and once it is done, restart your computer

2. Run DISM scan

   DISM scan is similar to SFC scan but it tackles different types of system file corruption and it is recommended to run it also after SFC has been completed. Please note that for DISM scan to be successful you will need a stable internet connection since DISM will replace corrupted files with new ones downloaded from Microsoft. To run it do the following: Press ⊞ WINDOWS + X to open the secret menu Left-click on the command prompt (admin) inside command prompt type: exe /online /cleanup-image /scanhealth followed by ENTER, then type: Dism.exe /online /cleanup-image /restorehealth also followed with ENTER. Leave scan to finish and reboot your PC

As you know, the Mobile Hotspot feature is used to share the internet connection with other devices using Wi-Fi signals. These Wi-Fi signals are later caught by other devices using their Wi-Fi and then the internet connection is shared once they are connected. However, recently, some users reported that their devices weren’t able to see the Wi-Fi network even if their Wi-Fi is on. This kind of problem could be caused by several factors but one of the main ones include the frequency at which the Wi-Fi network is being broadcasted. If you are one of the users who are currently facing this problem, read on as this post will guide you on what you can do if the Mobile Hotspot or Wi-Fi connection does not show up or is not detected on your Windows 10 device. In most cases, there are only two frequencies at which a Wi-Fi network is broadcasted. They are broadcasted either at 2.4 GHz and 5 GHz. The ones that are broadcasted at 5 GHz need specific hardware since it is a newer technology compared to the ones at 2.4 GHz. There are several other pieces of equipment as well as electrical appliances that operate at 2.4 GHz that includes microwaves as well which causes disruption in the signal strength of the Wi-Fi network. Moreover, aside from signal interruption, this issue with the mobile hotspot might also have something to do with the network-related drivers in your computer. Thus, to fix the problem, here are some suggestions you should follow.

Option 1 – Try toggling the Network band or the frequency at which the Wi-Fi network is broadcasted

• First, open the Windows 10 Settings app and then navigate to Network & Internet > Mobile hotspot.
• From there, click on the Edit button located under the Network name, Network password, and Network band.
• After that, set the Network band to be at 2.4 GHz and then click on the Save button.
• Once done, restart the Mobile hotspot in your Windows 10 device as well as the Wi-Fi connection of the device that’s trying to connect to the hotspot.

Option 2 – Try running the Network Adapter Troubleshooter

If the first option didn’t work, you might also want to run the Network Adapter Troubleshooter. You can use it to troubleshoot the problem with the Mobile hotspot, to run it, follow these steps:

• Open the Search bar on your computer and type in “troubleshoot” to open the Troubleshoot settings.
• Next, scroll down and select the “Network Adapter” option from the right pane.
• Then click on the Run Troubleshooter” button.
• After that, your computer will check for any possible errors and will pinpoint the root cause of the problem if possible.

Option 3 – Try updating the Network adapter driver

As mentioned, the problem could also be due to the network-related drivers. So it probably might be the reason why you’re mobile hotspot did not appear or was not detected. That’s why it is recommended that you update the Network adapter driver and to do it, refer to these instructions: Follow the steps below to update your Network Adapter Driver:

• Tap the Win + R keys to launch the Run window and then type in the “MSC” command and hit Enter to open the Device Manager window.
• From there, expand the list of all the network drives and update each one of them.
• Restart your PC and see if it helped in fixing the issue with the mobile hotspot.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

A PC that turns on by itself every so often can get quite annoying. Many users have faced this problem countless times. There are lots of possible reasons why your Windows 10 PC turns on by itself, wakes up from sleep, standby, or even when it’s shut down. To find out what exactly woke your computer, simply open Command Prompt as admin and type the following command:

powercfg –lastwake

Once you enter the command given above, it will show you the last device that woke your PC up. After that, you need to type in the next command:

powercfg –devicequery wake_armed

After entering the command, it will show you a list of all the devices that could wake your PC up. The goal in running these commands is to understand the reason what’s really causing your PC to turn on and see the reason is on the hardware level or not. Here are a couple of options you can try if your Windows 10 PC turns on by itself.

Option 1 – Try disabling Fast Startup

As you know, Windows 10 comes with a mode called Fast Startup which does not turn off the computer in the usual manner. This mode keeps your computer in a mixed state so that when you turn it on again, it will be a lot faster. However, as useful as this feature appear to be, some security experts find this an issue, for numerous reasons – for one, it can turn on your Windows 10 PC by itself. Thus, you need to disable this feature to fix the problem.

Option 2 – You need to stop the Task Scheduler from waking up your computer

There are times when the issue has something more to do with the software than hardware. It could be that you are using a Scheduled Task to get some work done on your computer at a particular time of the day or many times a day. That’s why if you really are using Task Scheduler, you need to change the Power settings of Windows to make sure that it ignores those tasks rather than deleting them instead when your computer is either on Hybrid or Standby mode.

• Open the Power Options and then click on “Change Plan Settings”.
• After that, make sure to choose the correct power plan and then select the “Change advanced power settings” option.
• Next, look for the Sleep tree and expand it to view the “Allow Wake Timers” option and then disable it. Disabling this option will make sure that none of the program that could wake your PC up when it’s either on shutdown or sleep mode. However, this only applies to laptops.

Option 3 – Try to disable Automatic Restart

There are instances when the computer crashes and the system restarts itself. This is actually by design – when your computer has been left on standby, the computer will restart and if the program repeats, it will keep on waking your PC up.

• In the Search bar, type in “system”.
• Once it appears from the search results, click on it.
• Next, select Advanced system settings on the left side and then go to the Advanced tab.
• From there, click on Settings under Startup and Recovery.
• Then unmark “Automatically Restart” and click on OK.

Option 4 – Adjust the Power Management option of both the Keyboard and Mouse

As you know, two of the culprits in waking your PC up are the keyboard and the mouse. If they’re slightly moved or hit, your PC turns on. To prevent these two from waking your computer up, you need to make some adjustments to their power management option since they have one. You can disable this option to ensure that they won’t wake your PC up unless you really want it to.

• Tap the Win + X keys and then tap M to open the Device Manager and list all the hardware on your computer. From there, select your keyboard or mouse.
• Next, right-click and then go to Properties and go to the Power Management tab.
• In this tab, uncheck the “Allow this device to wake the computer” box.

Note: Aside from the keyboard and mouse, if you are also using any gaming rig to play games on your computer, then you might have to disable their power options as well as they could also wake your computer. Just make sure that either the keyboard or the mouse has the ability to wake your computer up at the very least as it can be quite inconvenient to tap the Power button every time you want to turn on your computer.

Option 5 – Modify Wake On Lan

The Wake On Lan feature can bring back your computer online if it is connected to a network. This feature is useful especially when a computer wants to communicate or to send data or files to a network computer which should come online only when it’s requested. Wake On Lan is built into the hardware, i.e. network adapter so it is one of the possible reasons why your PC turns on by itself.

• Tap the Win + x keys then hit M to open the Device Manager and then under the Network adapters, look for the one that was listed above. Take note that you must not change anything with the ones that are listed as Miniport.
• Next, right-click and select Properties and then go to Power management and from there, uncheck the “Allow this device to wake up the computer” option. This will ensure that no PC on the network can ever wake your computer up.

Option 6 – Prevent any scheduled Windows Update and Automatic maintenance

It is also possible that the Windows Update has restarted your PC to complete the update. This depends on your active hours or a predefined schedule. AS you know Windows has a built-in Automatic Maintenance mode which wakes the computer up at the scheduled time and performs the system update. This could be one of the possible reasons why your computer turns on by itself. so to prevent any scheduled updates and maintenance, you can simply change the time for Automatic maintenance. How? Follow these steps:

• Open Settings then go to Windows Update and Security >Windows Update and select Active Hours.
• After that, type in “Automatic maintenance” in the search bar to change the time for Automatic maintenance.
• From there, you can adjust the timing or just uncheck the “Allow scheduled maintenance to wake up my computer at the scheduled time” box.
