Windows 7: Troubles in taking Ownership (Access Denied)

28 Sep 2012   #1

Windows 7 Professional 64 bit
Troubles in taking Ownership (Access Denied)

**Edit** I was able to take ownership of it thanks to the help of SIW2 as listed in his post here which helped me turn off UAC using regedit, I was thus able to give myself ownership and then give full rights back to the User account that I was using. My epic search has reached its end, for anybody who wishes to post other suggestions, I have left the original post as it originally was.


I have been attempting to help a friend with his computer because we have had something very interesting happen. I am told "Location is not available C:\ is not accessible. Access is denied." whenever I try to make any changes on the Desktop myself, such as adding new folders, text documents, drag-drop, and anything that I have tried. (I can download things from the internet and save them directly to the desktop).

I also am unable to open the C Drive itself, receiving the same error as mentioned before.

After hunting through many posts here on this forum I have learned and tried several things:

A: I have activated the hidden admin account using the command "net user administrator /active:yes" in safe mode, and have been trying to Take Ownership of the C Drive (many forums suggested that it would solve my problems) and have thus far been unable to do so.

B: The simple solution of opening up Properties -> Security -> Advanced -> Owner -> Edit... stumps me right there with the error of "Windows Security - Can't open access control editor. Access is denied."

C: People suggested adding a Register Key to create the "Take Ownership" button which would give me permission. I have tried two different Reg keys and both of them will work, but when I try and Take Ownership on the C Drive a cmd prompt will open, and reads: ERROR: File or Directory not found. before promptly quitting (only a well-timed screenshot caught what was actually written)

D: I have read a few ideas of what I can do in a cmd prompt (with admin privileges) to take ownership, one idea read as follows
CD \
ICACLS C:\ / GRANT Administrators:F
but when I type in "CD \" i am told 'Error: Access is denied.' in the cmd prompt.
A different idea read something like "takeown /f C:\ /r /d y" to which I receive the same error.

I can open up sub-files such as MyDocuments and other things like that, but the C Drive refuses to open itself up.

At one point I tried a system restore, and it indicated that it would begin working, and then the computer would reset itself, with no system restore having actually occurred. (I tried a restore in safe mode, and one in the Admin account normally)

It seems that many of the things that would require admin access, or rights (as indicated by the classic shield) I am unable to do, and yet others I can do. I can open up CMD prompt with admin privileges, but I cannot manage other user accounts under Control Panel "User Accounts" -> Manage another simply will do nothing, no error message or anything.

I hope this gives you a good enough idea of what we are dealing with, the computer is a Windows 7 Professional on 64-bit. Any thoughts or ideas are welcomed. Thanks,
