How can we know what is your current code? I looks like you did not really created a server, or created in-proc server/component.

I Literally Created exe server component(out-of-proc server), when I run number of client From same user then single instance of exe component is created which serves to client, but while doing this I run client which request for same exe server component from another user of same machine then new instance of exe component is created, but I want same instance has to shared among them.

I have exe server component, if client run under privilege command prompt then component server receives "-Embedding" parameter and register class object in running object table(ROT) and serve to first client, while doing this i run second client under same privilege same server component serves to client, but if i run another client under normal command prompt then new instance of server is created. why this?

That's a conceptual change. You created an Outproc COM server and that runs per user, but you need a Windows Service. The Windows Service runs independently from any logged-in user (typically with Local Systems account), and your client program can communicate with it via some remoting technology (e.g. WCF, SOAP, etc); it may even reside on a different machine and serve multiple users on multiple computers.
