The Windows Update Service helps in updating your Windows 11/10 system to the latest version and it is necessary because it pushes updates required by the operating system. The service is managed through the Service Manager. However, some users have reported a case where the Windows Update Service missing in services.msc in Windows 11/10. At times you may see error code 0x80070424.

Windows Update Service is missing (0x80070424)

While the basic cause is a missing file, a user reported that it was apparently removed by malware. Thus, it is advisable to perform a full system anti-virus scan on your system before proceeding with any troubleshooting mentioned below:

Run the Windows Updates Troubleshooter
Run an SFC scan
Use DISM to fix Windows Update files
Re-register or reset Windows Updates components
Use Registry fix
Reset your computer
Repair Windows using external media

Try the following solutions sequentially to resolve the issue in discussion.

1] Run the Windows Updates Troubleshooter

The Windows Update Troubleshooter can resolve a lot of problems related to Windows Updates. It can be helpful if you encounter the problem in the discussion. The procedure to run the Windows Updates Troubleshooter is as follows:

Click on the Start button and go to Settings> Updates and Security > Troubleshoot.

Select the Windows Updates Troubleshooter and run it.

2] Run an SFC scan

The System File Checker or sfc.exe is a utility in Microsoft Windows located in C:\Windows\System32 folder. This utility allows users to scan for and restore corrupt Windows system files. Since the main cause of the issue is missing files, you can consider running an SFC scan on your system

3] Use DISM to fix Windows Update files

If a generic SFC scan doesn’t work on your system, you could try a Windows Updates specific DISM scan.using the following command:

DISM.exe /Online /Cleanup-image /Restorehealth

This procedure will check for missing and corrupt files associated with Windows Updates and replace them.

If your Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files.

You will then be required to run the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess

Here you have to replace the C:\RepairSource\Windows placeholder with the location of your repair source.

Once the process is complete, DISM will create a log file in %windir%/Logs/CBS/CBS.log and capture any issues that the tool finds or fixes.

4] Re-register Windows Updates service/Reset Windows Updates components

If the above-mentioned solutions failed to bring any result, you could consider resetting the Windows Updates components. This is a long a complicated process but works well when done step by step. Usually, this solution should resolve the problem with Windows Updates, no matter what, but if it doesn’t help, you might have to consider resetting your system.

5] Use Registry Fix

Back up your Registry and also create a System Restore Point first and THEN download this file from our servers and extract its contents. It will contain a Fix-WUS.reg file. Double-click on it to add its contents to your Registry.

Check if it has solved the issue. If yes, good; if not, restore your Registry or your Windows using the created backups.

6] Reset your computer

Resetting your Windows system comes with two options: the first is to delete all files and programs on the system start new and the second is to reset the settings to default while keeping your files intact. It is advisable to start with the option to keep the files intact and if that doesn’t work, you can consider wiping data from your system after a proper backup.

7] Repair Windows 11/10 using external media

While resetting Windows 11/10 should clear most of your problems, if that doesn’t work, you could consider repairing Windows using external media. This would require a DVD or USB drive with a Windows ISO. The problem is that unlike previous versions of Windows, the recovery media usually doesn’t come with the package when you buy a computer. You could either order it separately or create it on your own.

We hope this guide helps in resolving your problem.

How do you reset service registration in Windows?

You must stop services such as wuauserv, cryptSvc, bits, msiserver, then delete or rename the SoftwareDistribution and Catroot2 folders. Once done, restart the services, and wait for the process to complete. The deleted folder will be automatically created. You must execute all the commands using Windows Terminal with admin permission.

What is the command to restart the service?

The service can be stopped using the command—net stop [service name] and started again using net start [service name]. This will restart the service. You can also execute them together, but it’s best to have a time gap between both so the service can complete their work.

That is all you need to know about the service error. Please let us know what worked for you in the comments section below.

Источник

Microsoft provides fixes for a lot of bugs as well as upgrades their software through Windows Update. Thus, your PC is bound to find trouble if it is not working.

The Windows Update Service or wuauserv handles the Windows update feature for the detection and provision of required updates to the computer. So, the Windows updates will not work and show Error Encountered while checking for updates if this service goes missing.

And on top of that, you will not even find Windows updates listed in the services list. But don’t panic. We have brought forth the working solutions to restore the Windows update service on your PC.

Table of Contents

The Windows updates service can disappear due to system file corruption, virus infection, or registry error which can be fixed easily.

So, let’s move through the fixes right away.

Run Windows Update Troubleshooter

The built-in troubleshooter in Windows can easily restore the missing Windows update service on your PC. Let’s see how you can use it.

Press Windows + ‘I’ to open Settings.
Find Troubleshoot and click on it.
Select Other troubleshooters.
Find Windows Update and click Run to start Windows Update Troubleshooter.
It will automatically detect the issue and fix it.
Restart your PC.
Now, press Windows + ‘R’ in the next boot and type services.msc to open Services.
Find Windows Update. However, most of the time, the restored file may be named wuauserv instead.
Double-click on the one you find.
Choose Automatic in Startup type and click Start.
Click OK to start Windows update services again.

The Windows update services are restored successfully now.

Run DISM and SFC Scan

Sometimes, the system files can get corrupted by virus infection or some other means. This can cause the system services to malfunction, including the Windows update services. To fix this, you can run the DISM scan. It will repair the damaged system files and fix your problem of missing Windows update service.

However, the DISM scan works by downloading healthy files through Windows updates server. Since your Windows update itself is not working, you should use another source of Windows to get the healthy files. Thus, you should first download the Windows ISO file and use it as the source.

Press Windows + ‘I’ to open Settings and go to the About section.
Note the architecture, build, and version of your windows.
Download the ISO file of Windows having the same architecture, version, and same or above build.
Mount the ISO file to prepare an installation drive.
Press Windows + ‘R’ and type cmd.
Press Ctrl + Shift + Enter to open Command Prompt with administrative privilege.
Enter the command dism /online /cleanup-image /restorehealth /source:D:\sources\install.wim /limitaccess.

For our computer, the installation drive of mounted ISO is “D:”. So, it may vary as per PC. You will have to replace “D” with the drive letter where the ISO file is mounted.
Restart your PC.

The Windows update service should be back now.

Repair Registry Entry

If the registry entry of Windows Update gets corrupted or deleted by some means, you will find the Windows Update Service missing. So, you should restore and repair the entry to fix the issue.

Using Backup From Another System

If you have another working system or can get access to one, you can restore the healthy file to your PC from there. Let’s see the way to do it.

Turn on the functioning PC and press Windows + ‘R’ to open the Run dialog box.
Type regedit.msc to open Registry Editor.
Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services.
Find the wuauserv key and right-click on it.
Click Export and save it with the same name.
Copy the registry file to a flash drive or external storage.
Run your PC and copy the file into it.
Open Registry Editor and see if your PC has the wuauserv registry key by navigating to the above-mentioned location.
If the file is present, right-click on it and select Delete.
Then, double-click on the copied file and click Yes to add the file to the registry.

Restart your system and run the Windows update to install updates and see if it solves the problem.

Creating New Registry Entry

If you do not have access to a working PC, you can create a new registry and add it on your own.

Note: We strongly recommend you to backup your registry prior to making any changes if your system is in working condition

Let’s see how to do it.

Open Registry Editor and look for the Windows update registry in the same way as mentioned earlier. If it is there, delete it.
Press Windows + ‘R’ to open the Run dialog box.
Type notepad and click Ok to open Notepad.
Now, copy the following code into it.
