    Check Your Internet Connection

    The first thing to check when a Windows update fails to download or install is your internet connection. Windows relies on your internet connection to successfully update files. An inactive connection interrupts that process, causing your updates to fail.

    Launch a web browser on your PC and open a site. If you can access the site, your connection is working. If your site fails to open, your internet connection has a problem.

    You can fix your connection issues by rebooting your router, reconnecting your PC to your network, and using other internet troubleshooting tips.

    Fix Windows Update Error by Turning Off Your Proxy

    Your PC’s proxy routes your internet traffic via a third-party server, sometimes causing problems with your internet-enabled features, like Windows Update. In this case, disable your proxy server and see if your issue is resolved.

    1. Open Windows Settings by pressing Windows + I.
    2. Select Network & internet in the left sidebar.
    3. Choose Proxy on the right pane.
    4. Turn off the Automatically detect settings option.
