DO NOT EVER display a UI from a service!!!  Services are background 
processes.  They are not supposed to interact with the user directly, with 
the exception of simply MessageBox() dialogs when notifications are needed. 
In fact, UIs in services are strictly not allowed anymore starting with 
Vista.  For a service to display a UI, the proper way to handle that (in any 
OS version) is to create a separate non-service application that runs after 
the user has logged in, and then have that application communicate with the 
service as needed using any of a number of IPC (inter-process communication) 
technologies that are available, such as sockets or named pipes.

Another reason not to use UIs in services - TService is multi-threaded, and 
the VCL's UI components are not thread-safe.

You should never have been doing that in the first place.
