Windows 10 New Feature: Controlled Folder Access to Protect Your Data from Ransomware

To better protect your valuable data from malicious apps and threats like Ransomware, Microsoft introduces a new feature called Controlled folder access in the upcoming Windows 10 Falls Creators Update. When enabled, it monitors the changes that apps make to the files in certain protected folders and sends you a notification when a blacklisted app is trying to make a change to these files.

To enable the feature, Open Windows Defender Security Center by double-clicking the Windows Defender icon on the taskbar or the hidden area on the taskbar.

By default, the following folders are already being protected once the feature is turned on:

  • Documents
  • Pictures
  • Movies
  • Desktop

If you have data saved in the folders that are not in the default protected list, you can add them by clicking Protected folders link and add them to the protected list in the next window. You can also enter network shares and mapped drives as well.

With the ransomware getting so crazy lately, this controlled folder access feature Microsoft has put it out in motion is a very useful and welcomed feature that could save a lot of people’s data down the road.

Note that Controlled folder access is a new feature that first appeared in Windows 10 Build 16232 for Windows Insiders. It’s still in beta and has a long way to go and to improve until it makes its official debut in Windows Fall Creators Update.
