Are you really sure you want to do this? You will have to set up the ASP.NET user, or whatever user your asp.net applications are running as with the ability to read and write to the registry. That is a huge security concern, you don't want you ASP.NET to be able to do that because any web application that is running on that machine would have the ability to read and write to the registry.

Is there another way around this ? What is the reason for it, perhaps there is another potential solution.
