Select “Update & Security” under the category heading
Under the “Troubleshoot” tab, select “Advanced options”
In the “General” section, uncheck the box next to “Automatically download and install security updates”.

2] Check the status of Windows Update Services that are related
If you’re having trouble connecting to the internet, it could be because one or more of your network devices isn’t working properly. You might even find that some of your computers aren’t able to connect to the Internet, while others work just fine. This article explains how to troubleshoot issues with Windows Update Services, including what to do if you see error messages like “The Windows Update Service failed.”
3] Put Windows Update back to how it was.
Resetting Windows Update to default might solve the problem. This is how it works: When you install Windows 10, Microsoft installs some optional features like Windows Defender, Cortana, and others. If you don’t want those features, you can disable them during installation. But there are times when you do want to use them later. For example, if you’re upgrading from Windows 8.1 to Windows 10, you’ll likely want to use Windows Defender to scan your system for malware. Or maybe you just want to turn off Cortana because she’s annoying. In either case, you can easily restore the defaults by running the following command: “wusa /reset /noforce”.
