Answer 1

When you double-click on a registry file, the contents are added to the Windows "Registry", which is just a big database of stuff that defines how the systems works, where things are stored, and so forth.

To get rid of it, you can restore the most recent back of the registry files.  This is the most reliable, since I suspect you don't know what the registry contained before you installed the reg file.

There is a good article on backing up and restoring the registry here:  http://support.microsoft.com/kb/322756

Answer 2

this message board is not displaying the entire text to your reg file.

What a  reg file does is edit or enter information into your registry.

My question is what was the purpose of that reg file when you installed it? Reg files can't be exactly 'uninstalled' you have to go into the registry using regedit and edit it yourself to remove the reg file entry. OR rewrite the reg file to 'edit' it by 'installing' the edited reg file.

--------------------------------------...

OK so I did some research on that reg file that you downloaded. It is a reg file that will allow access to the control panel in order to remove Windows Defender. if you want to now make the control panel invisible again, you can edit the reg file by changing the dword from 0 to 1.

So both entries should be changed from "NoControlPanel"=dword:00000000 to "NoControlPanel"=dword:10000000

Save your edited reg file, then merge it.



That should make the control panel invisible again. But why?

I'd leave it available.

If I am understanding what you did correctly, you do not / cannot delete it.  What you actually did was update your computers Registry file.  Hopefully you did a backup of your Registry file before you installed the one you downloaded.  If you did then you can restore your Registry from the backup.  

The Windows Registry is the database in which the operating system stores most of its settings. It's where programs store their settings. It contains information about what hardware is installed on the system. Importantly, the registry defines relationships between different parts of the operating system's user interface. For example, the registry defines what you see on the desktop; how the Start menu and taskbar work; and how the operating system starts.
