    A revisit: Unable to delete/take ownership of registry keys

    Really need some help with this.
    Running Win7 Enterprise
    There are currently 11 reg keys that I know of that I cannot take ownership of or delete. 9 are magicjack keys and 2 are erroneous file types (jv16 power tools).
    What really concerns me is that I'm logged in as admin but do not have complete control of my computer. I was a computer analyst for over 15 yrs. and was always able to solve problems like this. Win7 has me stumped.
    How can software lock reg keys to the point that an admin cannot delete them?
    TIA

    Try this command line tool from Mark Russinovich;

    This command-line utility searches for and allows you to delete Registry keys that contain embedded-null characters and that are otherwise undeleteable using standard Registry-editing tools. Note: deleting Registry keys may cause the applications they are associated with to fail.
    or

    Hey CLiNT, Thnx for the tips. Tried both. Neither worked. PCregedit would not boot my computer. 5 or 6 errors and didn't recognize my video card... which I thought was kinda strange cuz it's about 2.5 yrs. old. That could be a really helpful proggie.

    Tried it. Doesn't do jack. Didn't delete the reg entries or one of the mj dirs. Waste of time.

    Have you tried running regedit from an administrative command prompt?

    Open a command prompt using "Run as administrator" and then type "regedit", which will bring up the regedit interface.
    Create a new drive image before making system changes, in case you need to start over!

    Tried this procedure, but is very complicated. The MS file downloaded and installed, but when run, had thousands of errors. When it completed, I went to the registry keys I want to delete and was still unable to take ownership/delete them. I have one more thing I'm going to try and, if that doesn't work, it's gonna be a clean install or switch to Linux.

    There is a reason it is complicated. Security and ownership has become a tool to use against malware. Starting with Vista even though your user account is a member of the administrators group it does not have the same unfettered access to your PC as the builtin Administrator account. Thus you end up with UAC, Trusted Installer, and "Run as administrator". If you run regedit as administrator you can take ownership of any registry key. You should be very careful doing this as you can make your system unusable by changing permissions on some keys.

    Feel free to change to a Linux OS if you wish. You'll find the same if not more restrictions on everyday user accounts. Security is the same reason on Linux that you have to login as "root" to do administrative tasks.

    UPDATE! Alright. I tried taking ownership of 2 keys on another computer running a different ver. of w7:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\U SBSTOR\
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\U SB

    These 2 keys were mentioned on several sites that had procedures listed for removing magic jack. These keys do not need to be deleted. It's some keys under these that are the culprits. I was not able to take ownership on the 2nd computer either. These keys have nothing to do with mj, so w7 is locking them.
    Any input would be greatly appreciated.
    TIA

    I was logged in to the builtin admin acct.

    When I start regedit with "run as administrator" I can change the ownership on any key. Are you starting regedit with "run as administrator"?

    Since you are running Win7 Enterprise, are there policies in place to disallow use of regedit?

    Yes, I am "run as administrator". Running Ent. on my home computer. No restrictions.
    Have you tried taking ownership of the keys I listed above?

    Angry Unbelievable!

    I thought maybe it was cuz I was running Enterprise, so I tried it on my laptop that runs Home Premium and had no joy. I don't understand this.

    I just tried it again on my laptop. Logged in as system admin. Ran regedit as admin. Went to the USB key and tried to take ownership. ACCESS DENIED!

    Joe, you got any idea what's goin on here?

    Here's the steps I used.

    Click on the Start orb.
    Enter "regedit" (without the quotation marks) in the search bar.
    In the search results area, right click on regedit.exe and select "run as administrator".
    Navigate to the key and right click on the key.
    Select Permissions.
    Click on Advanced button.
    Click on "owner" tab.
    Select the user to be the owner or use "other users and groups" button to select a user.

    OK your way out.

    Joe
