Windows Update Error 8024401F occurs when your system fails to connect to Microsoft’s update servers, commonly due to VPN or proxy interference, unstable network connections, or third-party security tools disrupting the update process. This problem affects Windows versions 7, 8, 8.1, and 10.
To resolve this issue, start by disabling any VPN or proxy settings you’re using. These can block or reroute update traffic in a way that causes errors. Next, temporarily deactivate your antivirus and firewall to ensure they aren’t interfering with update services.
After disabling these tools, reset Windows Update components by opening an elevated Command Prompt and entering the following commands:
These commands force Windows to rebuild its update cache, which often fixes download and installation issues. Once that’s done, run sfc /scannow to repair any corrupted system files, then restart your computer.
