Manually editing Windows Registry is fairly easy if you know what you are doing. At times, while attempting to modify a registry value or key, you might get an error with “Error Editing Value – Cannot edit: Error writing the value’s new contents” message. You get the “Error Editing Value – Cannot edit: Error writing the value’s new contents” error if you don’t have the permissions to change or modify the Registry key or value which you are attempting to modify. No, you don’t need to take ownership of Registry all the time. Only Registry keys or values that are throwing the above error require you take ownership. Note that you can’t take the ownership of an individual Registry value. Instead, you need to take the ownership of the parent key. There are two ways to take ownership of Registry in Windows 10.
