Windows error code 0x80070426 happens when there is a problem with the Windows Update service. This service is responsible for checking for and installing updates for Windows. When this service is not working properly, it can cause this error code to occur. There are a few different things that can cause this service to not work properly, including:

-A corrupted Windows Update database

-A damaged Windows Update service registration

-An incompatible Windows Update service

-A damaged Windows Update service DLL

Each of these issues can cause the Windows Update service to not work properly, and as a result, cause error code 0x80070426 to occur. In order to fix this error, it is important to first identify which of these issues is causing it. Once the cause is identified, there are a few different ways to fix it.

-If the issue is a corrupted Windows Update database, the fix is to reset the Windows Update service. This can be done by going into the services manager and stopping the Windows Update service. Once it is stopped, you will then need to delete the C:\Windows\SoftwareDistribution folder. Once this folder is deleted, you can then start the Windows Update service again.

-If the issue is a damaged Windows Update service registration, the fix is to unregister and then reregister the Windows Update service. This can be done by going into the Command Prompt and running the following commands:

net stop wuauserv

regsvr32 %windir%\system32\wups2.dll

net start wuauserv

-If the issue is an incompatible Windows Update service, the fix is to install the latest version of the Windows Update service. This can be done by going to the Microsoft website and downloading the latest version of the Windows Update service. Once it is downloaded, you will need to install it and then restart your computer.

-If the issue is a damaged Windows Update service DLL, the fix is to register the DLL file again. This can be done by going into the Command Prompt and running the following command:

regsvr32 %windir%\system32\wups2.dll

Once this command is run, you will need to restart your computer.
