How to Set Up Windows Defender to Scan on a Schedule in Windows 8 and 8.1
This tutorial will show you how to run a quick or full scan of your system with Windows Defender on a schedule you set in Windows 8, Windows RT, Windows 8.1, and Windows RT 8.1.
You must be signed in as an administrator to be able to do the steps in this tutorial.
The Windows Defender scheduled scan will run in the background
of Windows 8 at the time you set it to run. When it is running, you will notice the Action Center
icon on the taskbar notification area will display the black maintenance icon under it like below. You can click/tap on the Action Center icon, and click/tap on Scheduled Scan
link to open Windows Defender to see what it's doing if you like.
