After finding many users complained that Windows Defender has deleted a wrong file or folder on their PC, we decide to do something to help. That's why we introduce the reliable and powerful data recovery tool to help them recover Windows Defender deleted files.

How to Get Files Deleted by Windows Defender

1. Download MiniTool Power Data Recovery Free Edition V7.0 or obtain a Personal/Commercial /Enterprise/Technician License. There are two main differences between a free edition and an advanced edition:

a). The free edition has a 1 GB data recovery limit while the amount of data that you can recover with an advanced edition is unlimited.
b). The "Export Scan Result" is available in all editions while the "Load manually saved scan result" is not usable in the free edition.

We'll take the personal license as an example to show you how to recover your deleted files in Windows 7.

2. In this step, you can download the setup program directly and copy & paste your license to register at the end of the installation. Or you can register from the free edition by clicking on "Register" on any interface.

4. Wait for the scan of the selected drive. After the loading files process was finished, all found files and folders will be displayed in another software interface.

5. Finally, please check the Windows Defender deleted files you want to recover, and then press "Save" button in the lower right corner to set a storage directory for them.

Yet, sometimes, you may not be able to find needed files from the scanning result of "Undelete Recovery" especially when C: drive is the object of the scan (since many files will be saved to the system drive as long as the system is running and the system drive is easy to become the object of attacks). On this occasion, we advise you to choose "Damaged Partition Recovery" and perform a full scan to C: drive in order to detect more files. At last, you should check the files to recover by pressing "Save" button.

Summary: in this part, we're going to tell you some useful tips of using Windows Defender. We'll mainly show you how to stop Windows Defender from deleting a file mistakenly anymore and how to disable/turn off this tool temporarily or permanently.

As you all know, Windows Defender (which is called Microsoft Anti Spyware before) is an antivirus program designed by Microsoft Windows to protect your computer against malicious codes, such as viruses, spyware and rootkits. It is able to run on Windows XP and Windows Server 2003, and it has been built in Windows Vista, Windows 7, Windows 8 and Windows10.

Unlike other similar free products that can only scan the system, Windows Defender is able to do many other things: monitor the system in real time, remove the installed Active X plug-ins and clear the history of most Microsoft programs and other commonly used programs.

But as we know, Windows Defender may remove useful files by taking them as threats sometimes. Considering this, we feel it's necessary to show you how to prevent Windows Defender from deleting a needed file mistakenly. Here, we provide two methods. (In the following content, we'll still take Windows 10 as an example)
