It appears that this info is embedded in the project template definition. For instance, if I create a project using the "Console Application" project template, it uses:
C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\ProjectTemplates\CSharp\Windows\1033\ConsoleApplication.zip
Looking inside that zip file there is an AssemblyInfo.cs file which contains:
[assembly: AssemblyCompany("$registeredorganization$")]
[assembly: AssemblyProduct("$projectname$")]
[assembly: AssemblyCopyright("Copyright © $registeredorganization$ $year$")]
So if you can't change the registration info of your machine like others have suggested, you could just update this file here
