Windows 10: Cannot Decrypt Files Error: 0x80071771

Here's the story.I'm running Windows 11, I encrypted my files using EFS, all of my encrypted files are in E: drive, now I reformatted my pc to have a new reinstallation of Windows 11, after booting of the freshly installed Windows 11, I transferred my encrypted files to my new SSD F: drive. Now, I did all the instructions in the internet like creating a Everyone and giving full access, but unfortunately it still doesn't work. Is there any I can decrypt nor recover my files? I also didn't know that time that I have to back up some keys. Please help.

:)

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are unable to access the files that you have encrypted and you receive an error while decrypting the files.



I suggest you to refer the suggestions provided by Shafeeq_Khan in the thread

0x80071771 “The specified file could not be decrypted

Hello adilnumair,

Welcome to Microsoft Community.

Have you exported and made a backup for the key certificate before? If so, you can import it back, like the suggestion in this post: Error 0x80071771 The specified file could not be encrypted - Microsoft Community





If this doesn't work for you, I'm afraid that you may need to contact a third-party data recovery service and ask them if there is something wrong they can help, as Microsoft doesn't have other ways to decrypt a file encrypted by BitLocker. As for what data recovery service can help you decrypt your files, this is beyond the scope of the Microsoft community to answer, and you will need to search for it yourself through search engines.

Also, if a file has been encrypted by BitLocker, it takes some time to decrypt the file and it will not take effect immediately. I am not sure if you are trying to access the file while the decryption is still in progress. If you do have such an action, it may cause the file to be undecrypted.

Feel free to let me know if you have other concerns.
