Prevent programs from suggesting changes to my default search provider

[Major]

Hi, is there anyone please who knows the tweak for "Prevent programs from suggesting changes to my default search provider". I have tried to change it manually and see what are the changes in the register but without success.

Thanks

If it's any help to you, when you put a checkmark in the box next to:

"prevent programs from suggesting changes to my default search provider"

as described here:

Adding and removing that checkmark makes Binary Data changes in the

following Key:

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\User Preferences

"6256FFB019F8FDFBD36745B06F4540E9AEAF222A25"

Type: REG_BINARY

Thank you very much. I have tried it but without success because i have done the change then i have exported the key in the registry editor. But when i wanted to double click on the key exported it tells me:

Can not import C:\...

"Not all data was successfully written to the registry. Some keys are open by the system or other processes"
