Removing product key from registry for norton 2007

[Ekavir]

Hello
I want to remove NIS 2007 key from registry can you guys help me.
I am using Norton Internet Security 2007 for last 3 months but now i want to remove the product key.
I know the key is placed in registry but don't know how to remove it.

Is it a trial version or a full version?

[dhanubaba]

go to registry Edit by type regedit on RUN
then go to local machine and find Nortan and delete

Will not it be risky to simply remove all the Nortan registry keys straight away? What if the word Nortan related to other programs as well ! This may affect those programs as well. Cannot I find the particular registry key for removing product key?

Thank you for your reply
