1. Restart Your PC
While it’s common advice for all errors, it’s important to restart your computer before moving onto further troubleshooting. Restarting can often clear up temporary issues, so you don’t want to waste time working on a problem that has a simple fix.

After you reboot, try to install the latest updates again at Settings > Update & Security > Windows Update. If you see the error again, continue on. Keep in mind that it’s not a bad idea to restart after performing each of the below steps, either.

2. Fix the Windows Update Service
Much of the time, Windows Update error 0x80070422 happens because of an issue with the Windows Update service. If you weren’t aware, Windows services are processes that run in the background, independently of your user account. Your computer has dozens of services, most of which run at startup and work silently.

The Windows Update service is one that’s built into Windows. If this stops working properly, Windows Update will fail to run properly. Thus, it’s a wise place to check first—just note you need admin rights to use it.

3. Restart Other Services
While you’re in the Services panel, there’s another service to check: Network List. This service is responsible for identifying networks your computer is connected to and keeping information about them, so you wouldn’t think it’s relevant. Despite this, many people have reported that restarting it fixes error 0x80070422.

In the Services manager, locate Network List Service. Right-click it and choose Restart to kill it and start it again, which will hopefully fix the problem.
