Disable Automatic update 
Windows provide a program that named Windows Automatic Update. Automatic Updates is a feature that comes with recent versions of Windows. When you’re connected to the Internet, Automatic Updates checks for new critical updates from Windows Update in the background.
You shouldn’t notice the process because Automatic Updates uses leftover bandwidth on your Internet connection. This means that large downloads may take place over a period of time, depending on the bandwidth. If a download doesn’t finish during the period of time you’re using your computer, it finishes the next time your computer connects to the Internet.
By using Automatic Updates, you’ll get the latest important security updates delivered to you as they are made available. Microsoft offers updates to help correct issues that may make your computer vulnerable to virus or worm attacks that spread rapidly over the Internet. We strongly recommend that you set Automatic Updates to use scheduled installation (the default configuration), not just because of the convenience of having the most critical updates delivered to you, but because it helps ensure that your computer stays up to date and secure.
