.php extension just won't appear in the 'New' context menu

I have been playing with the registry, customising my 'New' content menu that appears when I right click in windows explorer. I added the .php file extension to this list, which worked when I first did it a little while ago. I have recently noticed that it is no longer in this list, and no matter how many times I delete the entry and re-add it to the registry, it just won't appear in menu.

This is the current registry entry for .php:

Code:

[HKEY_CLASSES_ROOT\.php]

[HKEY_CLASSES_ROOT\.php\ShellNew]
"NullFile"=""

And I've also got this for phpfile:

Code:

[HKEY_CLASSES_ROOT\phpfile]
@="PHP Script"

[HKEY_CLASSES_ROOT\phpfile\Shell]

[HKEY_CLASSES_ROOT\phpfile\Shell\Edit with Adobe Dreamweaver CS5]
"LegacyDisable"=""

[HKEY_CLASSES_ROOT\phpfile\Shell\Edit with Adobe Dreamweaver CS5\Command]
@="\"C:\\Program Files (x86)\\Adobe\\Adobe Dreamweaver CS5\\Dreamweaver.exe\",\"%1\""

[HKEY_CLASSES_ROOT\phpfile\ShellNew]
"NullFile"=""

Is anyone able to spot what I've done to make the option not appear in the New context menu like it once was?

Any help will be greatly appreciated.

Thankyou for the reply, but if you look at my original post, you will see that I have already done what you are linking to.

I also mentioned in my original post that I have already done it previously, and it worked, however for unknown reasons, it doesn't work anymore..

How would I take ownership of the key?

I went through that, but it didn't seem to change anything? When I was clicking on permissions, it told me that the permissions for .php were ordered incorrectly, so I clicked reorder, but that didn't seem to help.. Would I have to restart the computer for the effects to take place?

Yeah I was able to delete the key before, and have re-added it.. I'm guessing there isn't much else that can be done?
