Without a doubt, Microsoft Defender Offline is a superb offline scanning utility that operates from a secure environment, without the need to start your OS. This tutorial explains how to run Microsoft Defender Offline in Windows 10, Windows 8.1, and Windows 7.
When should I refer to Microsoft Defender Offline?
Consider running Microsoft Defender Offline in times when:
- Windows Security (referred to as Windows Defender Security Center in earlier versions of Windows) locates rootkits or other exceptionally stubborn malware on your device and notifies you to run Microsoft Defender Offline. You might encounter an alert indicating that malware was detected on your workstation, or get an alarm in Windows Security mentioning that extra cleaning is needed.
- You assume your system might have a threat that’s concealed in it, however, your security program doesn’t identify anything. In this case, you can refer to a Microsoft Defender Offline scan via Windows Security preferences. This is how to make it possible:
- Go to Start, and then choose Settings > Update & Security > Windows Security > Virus & threat protection.
- In the Virus & threat protection area, implement one of the following measures:
- In an up-to-date version of Windows 10: Next to the Current threats, choose Scan options.
- In earlier versions of Windows: Next to the Threat history, click on Run a new advanced scan.
- Choose Microsoft Defender Offline scan, and then click on Scan now.

You’ll be notified that you’re going to be logged out of Windows. Once this is done, your PC will reboot. Microsoft Defender Offline will be started and initiate a quick scan of your computer in the recovery environment. Once the scan is completed, (normally it lasts for about 15 minutes), your computer will automatically reboot.
Where can I locate scan results?
To examine the Microsoft Defender Offline scan results:
- Choose Start, and then go to Settings > Update & Security > Windows Security > Virus & threat protection.
- In the Virus & threat protection window in Windows 10, in Current threats, choose Scan options, and then go to Protection history (In earlier versions of Windows it might indicate Threat history).

- Check your workstation for threats and other infections.
- Delete any malware that’s detected from your system.
Windows Defender Offline will guide you through these four steps referred to above while you’re using the utility. In case you’ve been prompted in Microsoft Security Essentials or Windows Defender Security Center to download and execute Windows Defender Offline, it’s surely crucial to obey these guidelines. Fulfilling this command gives confidence that your information and the system, in general, aren’t compromised.
To begin with, get a blank CD, DVD, or USB flash drive with a minimum of 250 MB of available space, and then download and execute the utility. You’ll be instructed as you proceed via the steps to create the removable media.
