Windows Defender: How to Perform a Scheduled Scan in Windows 10

Want to check for malware more often? We show you how to create a Windows Defender Scheduled Scan on Windows 10.


Though tries to perform scans when it won't have an impact on performance, it isn't' always successful. This has led to some turning it off entirely, which is naturally not recommended. However, you can use the task scheduler to run a scheduled Windows Defender scan at a time of your choosing.

Typically, Windows Maintenance runs a scan, which can include security, around 2 am. If you're sleeping, it can wake up your PC to do so, but night owls may find that interferes with their usage. Though scans use fewer resources than many other solutions, it's still heavy on the disk, which can mean slow loading or transferring.

Some have the opposite problem. As Windows Defender tries to schedule scans for when the PC isn't in use, it can be several days before it gets a chance. If you're the type of person who needs a guaranteed check every day, a Windows Defender scheduled scan is your only real choice.

Let's jump into exactly how to do that so you can keep your system safe:

How to Perform a Windows Defender Scheduled Scan

Scheduling a Windows Defender scan doesn't take long, but it does require the use of Task Scheduler, a useful tool that some may be unfamiliar with.

  1. Open Task Scheduler

    Press the Windows key and type “Task Scheduler”. Click on the result under the “Best match” heading.

  7. Adjust your power settings

    Under the “Power” subheading, tick “Start the task only if the computer is on AC power” and “Stop if the computer switches to battery power”. This will ensure Windows Defender doesn't drain your laptop's battery while you're out and about.
