Is it possible to perform Word document to Pdf conversion using DocIO in Windows Service?

What is the usage of Windows Service?
Windows services are normally used when an application needs to continuously run. A Windows Service will run even if no-one is logged on. Windows service can start running as soon as the machine is powered up, which makes ideal for running as a server, http server for example. No one is required to login.

Windows services has the following features.

• Don’t need to have a session running. This is good for security, and also reduces overhead on the server.
• We shall make use of some management commands like Start, Stop, Pause and Continue.
• We shall also handle server events such as shutdown.

Please refer the below MSDN link to know about how to create a Windows service application.
