Fix Windows Update error 0x80070490

If you see Fix Windows Update error code 0x80070490 while updating your Windows 11 or Windows 10 computer, try the following suggestions:

Run the Windows Update Troubleshooter
Check Windows Update Services
Run DISM to repair Windows Updates
Manually Reset Windows Update Components to default
Create a new User Account.

1] Run the Windows Update Troubleshooter

Run the Windows Update Troubleshooter and see if that helps. It has been known to help in most cases.

2] Run DISM to repair Windows Updates

In Windows 11, Windows 10, Windows 8.1 and Windows 8, you should run the DISM Tool to repair system image and restore system health, and see if that helps. Our Ultimate Windows Tweaker can help you run them with a click. The command to be used in an elevated command prompt is:

DISM.exe /Online /Cleanup-Image /RestoreHealth

When you run it, the DISM Tool will use Windows Update to provide the files that are required to fix corruption. But if your Windows Update client itself is broken, KB958044 says that you will have to use a running Windows installation as the repair source, or use a Windows side-by-side folder from a network share or from a removable media, such as the Windows DVD, as the source of the files, and then use the following command instead:

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

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

If you are running Windows 7 or Windows Vista, after running the System File Checker, you should use the System Update Readiness Tool to repair Windows Update.

3] Check Windows Update Services

Open Windows Services Manager and check the Windows Update related Services like Windows Update, Windows Update Medic, Update Orchestrator Services, etc are not disabled.

The default configuration on a standalone Windows 11/10 PC is as follows:

Windows Update Service – Manual (Triggered)
Windows Update Medic Services – Manual
Cryptographic Services – Automatic
Background Intelligent Transfer Service – Manual
DCOM Server Process Launcher – Automatic
RPC Endpoint Mapper – Automatic
Windows Installer – Manual.

This will ensure that the required Services are available.

Apart from the direct service, you should find the dependencies of Windows Update service and ensure if they are running or not.

To get started, search for “services” in the Taskbar search box and click on the search result. After opening the Services window, find out Windows Update, DCOM Server Process Launcher, and RPC Endpoint Mapper. Check if they are running or not.
