Help in recovering Omnia 2 registry file name.

[zuunoper]

I have a Samsung Omnia2 (I8000), with Windows Mobile version 6.5 Professional, CE OS 5.2.21863 (Build 21863.5.0.67). I have accidentally renamed a file in the registry to and I need to find out its original file name so that I can change it back.

The location of the file in the registry is:
HKCU \ ControlPanel \ Notifications \ {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx}
Where Xs are alpha-numeric characters of the file name I am trying to recover.
Its "value data" is: New e-mail massage

Any help is greatly appreciated. Thanks.
