This security feature comes with Windows 10 Fall Creators Update (v1709), and you will find it included in Windows Defender Security Center. If you enable Controlled Folder Access on any folder, your system will keep monitoring all the changes in real time and let you know if any unauthorized access is occurring. Moreover, if an unauthorized process tries to access that protected folder, it will be blocked immediately, and you will be notified right away.

If you enable Controlled Folder Access, all your Library folders such as Documents, Pictures, Videos, Music, Favorites as well as Desktop will be protected automatically. These are the default folders. However, the best part is that you can add any other folder to the list. One important thing is you cannot change the folder location or move that protected folder from one place to another after adding that to your list. If you do so, this security feature will no longer be able to protect your folder.

So how do you enable and use Controlled Folder Access in Windows 10? Open Windows Defender Security Center. For that, right-click on the Windows Defender icon and select Open. Select Virus & threat protection and scroll down to find Controlled folder access. By default, it is turned Off. You need to toggle the button to turn it On.

Then you will find two more options – Protected folders and Allow an app through Controlled folder access. Click on “Protected folders” to manage the folders that are being protected right now. You may not be able to remove any folder from the list, but you can certainly add more folders by clicking on the Add a protected folder button.
