From here, you can choose which folders will be protected and what apps are allowed to access them. But if you’ve already signed up, you can access the feature by going to Windows Defender Security Center and then enabling Controlled folder access. So far, only Windows Insider users have access to controlled folders. Some reports suggest that other threats like malicious file macros and viruses can be prevented by this feature. In theory, this should slow down a ransomware’s ability to encrypt critical information. With Microsoft’s new Controlled folders access feature, you can list certain documents and folders as “protected.” Only whitelisted apps can access and edit these folders, while any attempted changes by malicious apps are simply blocked by Windows Defender. While this patch shouldn’t be a substitute for antivirus software and data backups, Microsoft does think its new features can help people defend against current and future threats.

This update is a response to the global outbreak of ransomware attacks such as WannaCry and Petya.

Microsoft has created new security features for Windows 10 users.
