In order to ensure greater security and reliability of Windows operating systems such as Windows 7, Windows Vista, Windows Server 2008 and Windows Server 2008 R2, a lot of system files have been assigned and granted ownership and full control permissions to TrustedInstaller and has special restricted permissions to all other users, including administrators. While the design makes accidental deletion or change to system files, it makes job of technical users harder though.

Manually take ownership and grant full control permissions of the files (including executables) and folders to administrators or other users or groups are messy multiple steps process in Windows. There are multiple ways to make grant full control permissions and ownership to administrators easier, such as using Take Control Of command script or manually issue takeown and icacls commands in Command Prompt window. It’s also possible to add a right click menu item to contextual menu that appears when user right clicks on files and folders, that automatically take full control and ownership of the selected files or folders as administrators.

Right Click Menu Item to Grant Administrators Full Control Ownership

In order to add a “Grant Admin Full Control” command to Windows right click menu, just download the following registry registration entries file, and double click on the GrantAdminFullControl.reg to merge new registry keys and values to system. The registry entries have been updated from previous version. It works on both 32-bit (x86) and 64-bit (x64) OS and is non-recursive.

Download GrantAdminFullControl.reg

Tip: It’s possible to change “Grant Admin Full Control” to any name you like if it’s not to your liking. To change the name on the right click menu, just edit the .reg file, and replace the three Grant Admin Full Control string in the text file to your prefer name, such as Take Full Control Permissions, Grant Administrators Full Permissions, Give Administrators Full Control, Grant Administrator Rights and etc.

    If it doesnt work for you, follow these Steps:
    1. right click on the file and click on Edit
    2. replace all the “administrators” with your username
    3. save!

    To uninstall it edit the file again and place a – after every [
    example: [-HKEY_CLASSES_ROOT\*\shell\runas]
    and save!

      You should have exported your registry to save its settings before modifying the registry.

  • Larry Gomez

    Hi, at some time coincident with the installation of this registry, I have lost icons to default/generic icons. System restore has brought them back temporarily but reversing this installation to diagnose the problem has been yet another problem. How can I do an uninstall before I lose the time frame for System Restore?

  • Gar

    This whole process is a pain in the you know what. You have to grant permissions for each file and folder separately, if you have a large number of files and folders, from let's say an old harddrive with another operating system on it, you are SOL, because there may be 100's of files you need. Nothing I have tried works better than booting up that old OS and copying files to another harddrive by yourself. But if that OS doesn't boot up you are in deep trouble, because you will not be able to get your files off of it easily.

    Win 7 is a huge nightmare when it comes to this!

  • Nic

    May I ask, is there a similar way to easily remove a permissions listing from multiple files? I have downloaded music and most of them have inherited permissions from the previous owner… I would like to remove those if possible, but I was just wondering if it is possible to do so in large batches.

    Any ideas?

  • Beltiras

    I'm trying to change the jEdit config file modes/catalog.xml. Win7 just won't let me de-flag the modes directory as read-only, even after using your script. The idea is solid and I looked @ the .reg, it's clean code and I understand the solution. Win7 is just bugged. Thank you for your good effort.

  • Great post – but this still doesn't solve an issue for me. Before removing the Windows 7 RC I backed up all my data on an external hard drive, then installed the fully Windows 7, then tried copying all my data back accross. The vast majority worked apart from 2 folders. The files in these folders have green text for their file names. When I right-click > Properties > Attributes: Advanced button > the following option is ticked: Encrypt contents to secure data. Unticking this and saving it produces an error "You will need to provide administrator permission to change these attributes. Click Continue to complete this operation."

    After clicking Continue – I get an error – Access is denied.

    This happens even after running your right-click script, or manually taking ownership. Very annoying!

    Thanks so much

    I needed to gain access to my password protected Docs folder in the HD from my old Win XP PC through my new laptop running Windows 7 Home Premium. Instead of having to gain ownership of each file individually this allowed me to do it in one go – it took about a minute to gain access to 9.05 GB of documents. Genius!!!

    Now if someone can make WMP 10 work on Windows 7 without downgrading to the 32 bit OS my life will be complete!

    to delete it open regedit the go to edit find in find type grant and press enter then delete every registry you'll see then go to edit and press find next delete it also do it until a these reg appear (DEFAULT



    Dont delete those. :)

  • Jon

    Thanks so much for this, I took it one step further. I had a bunch of picture files that went from XP to Vista Ult to Win 7 Ult. In win7 admins had full control and even though my user was in admin groups, I couldn't even preview the picture files and of course you can't multi-select to update the security on picture files… really? So I edited this reg file changed adminsitrators to my username and added that to my reg .. mahe it Grant Me Full Control .. works perfectly. I can see my picture files now.. THANK YOU!!

  • jabbaz

    Sure after i disabled uac. But in win7 it doesn't matter that its turned on or off.

  • jabbaz

    You are a lifesaver!

    Even if I did disable UAC, this crap didn't allow me to my own files. I agree with security, program-execution prevention, but if I, repeat I want to start a program, why cant do it. The main problem was an executable file with another extension. No run as administrator. In special settings I cant grant access to a folder or a file to myself as administrator. So I agree with security, but in the world there are people who dont use their computer just for power on->internet explorer->office->minesweeper->off. Windows8 slogan will be: are you sure? or what. Even when microsoft proudly announced that in windows7 uac is much more user friendly. It must be but in vista i was able to access my files.

  • cyclehacker


    open the .reg file in Notepad and insert a hyphen in each of the registry values.

    i.e. change [HKEY_LOCAL…]

    into [-HKEY_LOCAL…]

    Save it as delete_GrantAdminFullControl.reg or whatever you'd like and run it if you don't like the feature. Same with any registry file you want to try out.

    You can also just delete a value but leave a key by adding the hyphen after the equals sign in the file.

  • cshark

    This tip turned out to be a lifesaver. The key is quite safe. All it does is to add a right-click context menu, which can be invoked to execute a command prompt to take ownership of the file or folder. Without this I would have been forced to downgrade to Windows XP. I was trying to copy custom files from an old hard drive mounted in a new machine and kept getting "file access denied" errors. The solution actually was to take ownership of the files on the hard drive I was attempting to copy from. (This hard drive will be trashed when copy is complete so there's no security risk) I suppose if you're an IT admin you might want to remove the registry key when finished or (in Windows 7) set up a system restore point before executing the regedit but as a home user who just wants control of my own machine I see no reason to not keep it, and I hope Microsoft eventually includes this in Windows 7.

  • sianz

    @Phred, no, in IT, you learn that registry editing is at your own risk, don't do it if you have no idea what you are doing.

  • Phred

    In IT we all learn about backup – so that we can return to where we were originally, don't we?

    So where is the instruction to uninstall this registry entry?
