How to list and activate services from command-line console

My colleague had this unusual problem with his computer (actually it was a virus) and he had no access to the Services console in Administrative Tools but at the same time he had to run a service. As a solution we decided to use a command-line console. Please have a look below to find out how you can do it.

To list all up and running services type: net start
To list all inactive services type: sc query type= service state= inactive
With the second command you can check the name of your inactive service and to make it running type: sc start [service name]
