Windows Update error 80072EE2 usually means your system can’t reach Microsoft’s update servers—often due to network timeouts, proxy/VPN settings, or security tools blocking access. Start by ensuring your internet connection is stable and not routed through a proxy or VPN. Temporarily disable any antivirus or firewall software that could be interfering. Next, clear and rebuild update files by stopping the Windows Update services (
wuauserv, bits, cryptsvc) via Command Prompt as administrator, renaming both the SoftwareDistribution and Catroot2 folders, and then restarting the services. Run the Windows Update Troubleshooter from Settings → Update & Security → Troubleshoot to automatically fix common update issues. Finally, run sfc /scannow in an elevated Command Prompt to repair any damaged system files. Once complete, reboot your PC and check for updates again.
