 This article describes how to configure scheduled scans using PowerShell cmdlets. To learn more about scheduling scans and about scan types, see [Configure scheduled quick or full Microsoft Defender Antivirus scans](schedule-antivirus-scans.md).

-> [!NOTE]
-> When you schedule scans for times when endpoints aren't in use, scans don't honor the CPU throttling configuration and will take full advantage of the resources available to complete the scan as fast as possible.
