I have seen many posts that essentially indicate that UI components should not run as a service, I think rational I can not answer any UI event etc. But the fact is that there are many automation tasks that are only possible with Windows forms.
Here are some great examples:
-

-
Automate printing of MS-Word docs.
There was some trick to get pre-vista around this, but now there is no one my question is why this is the matter, and what exactly are the options ?
look and
Basically if two processes (for different users) share the same desktop, then a process can potentially execute the code that you want in the second process by sending a Windows message. , And it is called a slap attack.
There were so many discussions about whether this was a design bug, and after Vista, Microsoft decided to remove any interactive desktop support for the services because it was a potential security hole.
> As an alternative, you can view your image generation / printing code as a logged user, which has an interactive desktop access
