Why my pc is not downloading updates

Windows

To update your Windows 7, 8, 8.1, and 10 Operating System:

1. Open Windows Update by clicking the Start button in the lower-left corner. In the search box, type Update, and then, in the list of results, click either Windows Update or Check for updates
2. Click the Check for updates button and then wait while Windows looks for the latest updates for your computer
3. If you see a message telling you that important updates are available, or telling you to review important updates, click the message to view and select the important updates to download or install
4. In the list, click the important updates for more information. Select the checkboxes for any updates that you want to install, and then click OK
5. Click Install updates

Note: It is important that you do not shut your computer off or allow it to run out of battery during the update process. Doing so can cause a corruption of the operating system, which can often only be fixed by reformatting the computer.
