Windows 10: Files without permission after decryption

Hey guys!I usually install windows on SSD and use a regular HD to put some of my files and the files of my One Drive. In my last formatting I successfully installed the system, but my HD was encrypted by microsoft so I had to put the key to get access to it again. The problem is that some of my files remained without permission of access and OneDrive are not being able to synchronize it. They are safely in the cloud, If I download them they work, but the ones at my HD are locked. Anyone knows how to solve this and unlock these files?

Corrupted Win10 Profile, and Can't Decrypt Files

Hey there, Andre:

Thank you very much for your quick response. I finally got a chance to try troubleshooting per your suggestions. Here's what I came up with.

I apologize if I wasn't clearer in my issue originally. The files themselves were never actually ON the same drive as the OS. THE OS was on drive C. My files were on drive F. However, I had somehow encrypted those files with my profile... and now that
profile is corrupted.

I tried the suggestions on that you linked, and these are my results:

• Option 1: Change File Ownership to "Personal" in the context menu results in following error:
  
  • An unexpected error is keeping you from applying properties to the file. IF you continue to receive this error, you can use the error code to search for help with this problem.
  • Error 0x80071771: The specified file could not be decrypted.

• Options 2 and 3: Decrypt Folder or File, (respectively), in Advanced Attributes:
  • Trying to remove encryption by deselecting the "Encrypt contents to secure data" checkbox in the Advanced Attributes window yields the following error:
    • An error occurred applying attributes to the file: F:\EXAMPLEFOLDER\EXAMPLEFILENAME: The specified file could not be decrypted.
• Options 4 and 5: Decrypting Folders and Files in Command Prompt, respectively:
  • When running cmd prompt in Admin mode, and executing the cipher /d and cipher /d/s: commands, the following error is thrown:
  • F:\EXAMPLEFOLDER\EXAMPLEFILENAME\: the system cannot find the path specified.0 file(s) [or directorie(s) were decrypted.
  • This is problematic, because I can click on the folders and files themselves from the windows GUI.
    

I still have the corrupted profile on my computer... is there a way to reach into it to extract the cipher?

Thank you so much for your help! (Didn't expect to take a crash-course in Windows security, but there we are, LOL).

Best,

Chris
