There are several reasons why your system is unable to download the Windows 10 update, so here are some tips that can help you to solve this issue:

Turn off your Firewall and Antivirus software

Windows 10 is available as an update for your current OS, so you better check if a security program installed on your PC is preventing Windows Update Services (SVCHOST) from accessing the Internet. Temporarily disable your firewall, anti-spyware and antivirus software, and then proceed with the download. Open your antivirus settings and disable real-time protection. As for the firewall, go to the Control Panel > Windows Firewall Turn Windows Firewall on or off and then select Turn off Windows Firewall:


To restore the update process: click on the Get Windows 10 taskbar icon > View download progress:

Open a command prompt and then type the net stop wuauserv command to stop the Windows update service and then net start wuauserv to restart the latter.
