Why does Windows update automatically?
With automatic updating, Windows automatically checks for the latest updates for your computer. You don't have to search for updates online or worry that critical fixes for Windows might be missing from your computer.
You can fully utilize all of your HughesNet® data by rescheduling your updates to occur during the Bonus Zone (formerly Bonus Bytes) of 8 PM and 2 AM.
How do I reschedule/delay Windows Updates?
Open Control Panel and click on Windows Update.
