to enumerate all shellwindows

"COM object with CLSID {9BA05972-F6A8-11CF-A442-00A0C90A8F39} is either not
valid or not registered."

A service runs under a user other than the interactive user. If you want the
service to get access to the interactive user's desktop then you usually
should not write a service. Let me reiterate: windows services are not
supposed to have user interfaces, nor interact with the user desktop. You
get that error because you are not running the service under a user account.
What account are you using?

If you want to do any interaction with the visible desktop you should write
*two* processes. The service and a process that runs on the user's desktop.
The two should talk using some inter process communication. The second
process can have the code to access the user's desktop and then communicate
that data to the service.
