Windows 10: Administrator and c drive

Good day, so I'm the only administrator on my laptop but I can update, reinstall, restore...... Windows 10 my C drive is locked value shows 0 space I've tried command prompts I've tried everything with no luck even did the verification on Microsoft wedsite but still nothing I've been researching but nothing work I know the main thing is get admin rites but I'm lost please assist

:)

 

Lost access rights to C drive in Windows 10, even from administrator account!

Thanks for your prompt response and for the clarifications, Frederik.

Regarding your questions:

• Which folders are affected?
  • I cannot access C: drive at all. I can only use other disks. That's the main issue; I'd like to recover access, be able to run those programs that need files in C:, etc.
• The correct command would be takeown /f C:\ /r. You must run it under elevated privileges.
  • Thanks, but I've run the command using both my account (which is an administrator account) and the hidden Administrator account, in Safe Mode, and in all cases I've got an "access denied" message. The /r is just for
    recursivity, but it didn't work either.
• In your case I am happy to report that your files are safe.
  • Thanks. I know they are safe, but my concern is which solution can give me access to C: drive again, without having to format C: and lose my files. That's what I meant.

So, which would be your recommended next step for me try and recover the C: drive access.

Thanks!
