How to Enable Ransomware Protection on Windows 11

Microsoft’s Windows 11 operating system comes with an inbuilt antivirus tool that protects the computer from malicious attacks. The tool, named Microsoft Defender Antivirus, is the default application when it comes to protecting against viruses, spyware, rootkits, and many other types of malware.

Apart from that, it also supports ransomware protection, a feature that is not enabled by default but can be easily enabled through app settings. Ransomware is a form of malware that attacks and encrypts files on a computer, making all files inaccessible and unreadable. Once the attack is successful, the malicious individual will then demand a ransom to unlock the device and files.

Using Microsoft Defender’s Controlled Folder Access feature, the program monitors changes that apps make to your files. If an app tries to modify files inside a protected folder, the app is blacklisted and the user is notified.

In this step-by-step guide, we’ll show you how to enable Controlled Folder Access or Ransomware Protection in Microsoft Defender on your Windows 11 computer.

How to Enable Ransomware Protection on Windows 11

Step 1: Open the “Windows Security” application on your Windows 11 computer. To do this, open the Start menu and search for the application, then click on the application in the search results.

2nd step: When the Windows Security app opens, click on the “Virus & threat protection” option.

Step 3: In the “Ransomware protection” section, click on the “Manage ransomware protection” option.

Step 4: After that, enable the toggle switch for the “Controlled folder access” option.


That’s it. Once you have followed the steps mentioned above and successfully enabled the controlled folder access option, ransomware protection has been enabled on your Windows 11 computer. Microsoft Defender Antivirus will now monitor protected folders when apps attempt to modify your files. If it detects any suspicious activity, the system will send you a notification regarding the threat.
