  1. Encryption/Decryption


    I encrypted some files in Windows 7 using EFS. The computer was formatted to install Windows 10 and those files won't open now. I tried to decrypt them by using the PFX file, cipher command, and setting permissions but they couldn't decrypt the files. They were unable to show the owner Windows 7 PC user account but I set it to the current Windows 10 user account. Still wasn't able to decrypt them. Also, a registry for user account like S-1-5 appears.

    Can anybody help me in this case?

    :)

  3. Windows 10 Encryption/Decryption of Folders/Files 'Certificate'

    Hi,

    Thank you for posting in Microsoft Community.

    To understand the issue better, I suggest you to answer the below question.

    • Were you able to Encrypt the data?
    • Did you get any error message?
    • What exact issue are you facing with Encryption and Decryption?
    Note: The first time you encrypt a folder or file, an encryption certificate is automatically created. You should back up your encryption certificate.
    If your certificate and key are lost or damaged and you don't have a backup,
    you won't be able to use the files that you have encrypted.

    Keep us posted to help you better.

    URGENT!! Decrypt files after deleting encryption certificate

    have you tried To decrypt a file or folder:

    1. From the Start menu, select Programs or All Programs, then Accessories, and then Windows Explorer.
    2. Right-click the file or folder you want to decrypt, and then click Properties.
    3. On the General tab, click Advanced.
    4. Clear the Encrypt contents to secure data checkbox, and then click OK.
    When you decrypt a folder, you must decide whether to decrypt the folder only or to decrypt the folder and all files and subfolders contained within it. If you choose to decrypt the folder only, the files and subfolders within the folder remain encrypted. However, when you add new files and subfolders to the folder, they will not be automatically encrypted.
