How to take complete ownership of Windows Registry keys

Windows Registry is the repository where all the Windows System and the software configurations are stored. In most of the tutorials in our TWB blog we asked you to add, modify or delete the Windows Registry keys. But sometimes when you try to modify or delete the Windows registry keys, then Windows doesn’t let you to do so. This is due to your user or admin account doesn’t have the complete access to that particular registry key. To edit any protected or the system critical registry keys, then you need to take the complete ownership of that key.

How to take complete ownership of Windows Registry keys

It is very easy to take full ownership of Windows Registry keys, but remember that before editing Registry keys make sure that you have taken the back up of Windows Registry.

  • Press Win+R keys to launch RUN dialog box and type regedit and press enter to launch Registry Editor.
  • In the Windows Registry Window, navigate to the Registry key which you would like to take the ownership of.
  • Now right click on that intended Registry key and select Permissions option. When taking the ownership, you cannot take the permission of the values directly on the right pane. Instead, you need to take the ownership or permissions for the entire key.


  • This will open permissions window and here click on the Advanced button to tweak the special permissions. Now in the permissions window, select Administrators and then click on Apply and OK buttons. This will make the administrator account as current owner.


  • Now come back to the Permissions window and here select the Username, Administrator and then give the user complete access by selecting Full Control option under the Permissions for the Administrator section.

That’s it, from here you can modify or delete the any Windows Registry key. If you want the user account to have the complete ownership, then choose your user account rather than administrative account and give it full access.
