Launch an application from a service

[=?Utf-8?B?cmFuZHloQG5ld3Nncm91cHMubm9zcGFt?=]

I need to launch an application that interacts with the desktop from a
service. The catch is I need it to work at the CTRL-ALT-DEL screen when
nobody is logged in. How can I accomplish this?

You can't. There is no desktop until a user logs in.

Its possible in unmanaged world. i am not sure it's duable in .NET Framework.
Ideally it can be. Its complicated. ( Services start in system context, so
is the .NET framework. User does not need to be logged on )

You can launch applications in System context.
Scope of what these applications have access to may be limited. For example
if you want to write to registry hive under a user account.

This article may be a good starting point.
