    How to Decrypt Files and Folders Encrypted with EFS in Windows 10


    The Encrypting File System (EFS) is the built-in encryption tool in Windows used to encrypt files and folders on NTFS drives to protect them from unwanted access. EFS enables transparent encryption and decryption of files for your user account by using advanced, standard cryptographic algorithms. Any individual or app that doesn't possess the appropriate file encryption key cannot open any encrypted files and folders. Encryption is the strongest protection that Windows provides to help you keep your individual files and folders secure.

    This tutorial will show you how to decrypt your files and folders encrypted with Encrypting File System (EFS) in Windows 10 Pro, Enterprise, and Education editions.

    If you get an unexpected error message like below while trying to decrypt a file or folder, it means that you will need to restore the file encryption key that you backed up for the file or folder before you will be able to decrypt it.

    For option one no download link?
    "File ownership/Personal" not a built in context menu element isn't it?

    Hello Yasak, :)

    The "File ownership" context menu would only be available if the file has already been encrypted with EFS.

    You may be able to use it in Windows 10 as well if you like, but I haven't tested it yet in W10.

    Sory but it's not working on Windows 10.
    When merge regedit file nothing happen. Doesn't appear Decrypt/Encrypt option?

    Edit: Tried (W10)14393.1358 and 15063.413
    (Also tried W7 and W8.1 and it's working)

    Command:
    Code:
    fsutil behavior set disableencryption 1
    Disabling EFS does not decrypt files, a user might want to decrypt them to be able to access them after reinstall.
    Code:
    cipher /d /s:C:\
