I have copied some files from an XP computer to a PC running Windows 7. I am logged on as a user who is marked as an Administrator.

When I try to access the directory, I am told I don't have permission. Understandable, but what is odd is that I as an administrator don't have access to take ownership of the files. I don't have permission to add users in the ACL or to take ownership, indeed such options are greyed out.

Why as an administrator user can I not take ownership of files?

You don't even have the option to take ownership and then change permissions?? – nhinkle Apr 7 '11 at 22:35
This happened to me once on XP, but was easily fixed by a reboot. I don't know why, it doesn't make any sense, but maybe this could work for you, too? – Kromey Apr 7 '11 at 22:40
No, it's greyed out where I would select/search for users... – Sonny Ordell Apr 7 '11 at 22:41
it is possible to (un)intentionally mark yourself as having no access to a file or folder. in this case you might try having another administrator try taking ownership and then see if they can grant you access to it – Xantec Apr 7 '11 at 22:42

Try opening an elevated CMD window (right click> Run as Administrator) and type:

Net user administrator /active:yes

Confirm the command ran successfully then log off and log back in as the administrator account. After logging in as the built-in administrator account you should be able to take ownership.

Do not use this account for anything other than troubleshooting, never for everyday use.

If you wish To disable the account:

Net user administrator /active:no

Ah, this didn't work. I still don't have permission and the options are still greyed out as per my normal user account (which is also an Administrator). – Sonny Ordell Apr 8 '11 at 0:53
@sonny you are still unable to take ownership? – Not Kyle stop stalking me Apr 8 '11 at 1:46
Yes, I just get that I don't have permission to do this. Oddly enough even on the XP computer I get the same error with the XP administrator account. – Sonny Ordell Apr 8 '11 at 2:37
That's very odd @sonny, I had the same problem when I first migrating to windows 7 and it worked for me. I can't think of what else could be causing it unless you used, deny permissions but even then you should be able to take ownership. – Not Kyle stop stalking me Apr 8 '11 at 13:52
Oh yeah thanks @moab for the edit extremely valid point... in terms of UAC that would be like running as root. – Not Kyle stop stalking me Apr 8 '11 at 13:52

I had the same problem with my Windows 7 64-bit. I was finally able to do it as mentioned above by running Command Prompt as Administrator and then executing the following Batch File from the Dos Shell.

SET DIRECTORY_NAME="C:\Windows.old.000"
ICACLS %DIRECTORY_NAME% /grant administrators:F /t

Replace DIRECTORY_NAME with your directory you want to delete. This way you don't have to logout and come back in as a real Administrator instead of your normal login with Administrator "rights".

I do agree as mentioned above that one should not do everyday work as an Administrator.
