Windows Defender recently got a new feature, it’s to protect a folder with a password so that no other person than you can open that protected folder or modify the files inside – right now we was forced to install 3rd-party software to do this. “Controlled Folder Access” – this feature is a part of “Windows Defender Security Center” application. This feature doesn’t allow users to password-protect a single file or a single folder but with the help of this feature, you can restrict users from modifying a file or creating new files inside such a protected folder.
The new function requires the latest Windows Build, otherwise you won’t see the option! If it’s not there then it means that your Windows Build doesn’t support it, in this case just wait till you get the update.
