Windows updating error
Actually it happens when a few system services required to run Windows Update are not running or a few system files are not registered properly.
Microsoft has acknowledged the issue in a KB article and provided a fix for it.
In right-side pane, look for a DWORD Disable Windows Update Access.
I have a Windows 10 computer that has been unable to update to the latest released build since 10565 due to an error occurred every time when I was trying to update to any newly released built through Windows Update, see a screenshot below: As you can see, there isn’t much information there telling me what went wrong.
Many times when Windows users try to run Windows Update or try to access Microsoft update website or try to update Microsoft Security Essentials (MSE), they receive weird error messages like "0x80070424". After downloading, run the msi file and it'll fix the issue automatically.
Microsoft has also shared a few known methods to fix this annoying issue which are mentioned in a simple and easy to understand language as following: If any or all above mentioned services are not running or not set to Automatic, double-click on the service, set its Startup type to Automatic from the drop-down list, Apply the changes and click on "Start" button to immediately start it. If you find it, either change its values to 0 or delete the DWORD. Close Registry Editor and restart your computer to take effect.
