How to deactivate toast notification in windows phone 7.5?

Question

Windows phone

When a new SMS message arrives, a notification appears in the upper area of ​​​​the phone screen on Windows Phone 7.5 (in my case Lumia 800) containing the first line of the message and the sender.

Is it possible to disable these notifications or make them not show the sender and text?

Answer 1

This can only be done on an unlocked device by changing the keys in the registry.
You can't do this on a normal device.
