You can customize your templates by following the following advice. Using this method you would be able to get rid of the unused templates and create new ones suitable to your profession that can be shared.

Management Studio was designed with multi-user environments in mind. When SSMS starts, it checks a "common template folder" for templates and if any template is missing in a user's folder, it is copied from the common location. This lets an administrator add a template to a common location and all the users on the machine will automatically get a copy when they start SSMS.
If you want to permanently remove a template, first delete the file from ...\Documents and Settings\{user}\Application Data\Microsoft\Microsoft SQL Server\90\Tools\Shell\Templates\... (this removes the user's private copy), then remove the common template from %ProgramFiles%\Microsoft SQL Server\90\Tools\Binn\VSShell\Common7\IDE\sqlworkbenchprojectitems. Once the common version has been removed, SSMS won't be able to copy it to the user's template directory during application startup.
This works in SSMS 2008 using:
\Documents and Settings\{username}\Application Data\Microsoft\Microsoft SQL Server\100\Tools\Shell\Templates\Sql – for the private copy
%Program Files%\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\SqlWorkbenchProjectItems\Sql – for the common version
