Windows Update error 80244022 on Windows 10/8/7 indicates the system can't communicate with Microsoft’s update servers, often due to misconfigured settings, proxy/VPN interference, DNS issues, or antivirus/firewall blocking the connection. To resolve it, first ensure you're not using a proxy or VPN—or disable them temporarily—and verify your network allows access to Windows Update servers. Then clear and rebuild Windows Update components by stopping the services (wuauserv, bits, cryptsvc), renaming the SoftwareDistribution and Catroot2 folders, and restarting those services. Running the Windows Update Troubleshooter and executing
sfc /scannow in an elevated Command Prompt helps repair underlying system file issues. After rebooting, check for updates again with antivirus/firewall still disabled; once updates complete, re-enable your protection. For a full troubleshooting walkthrough, visit this guide.
