In 4.5 I believe it's named ""Providex IO Service""; do you see that listed? Not sure if it's the same name in v2013.
Fyi, I installed a new module for a 4.5 client that has this running. I did not disable it during the install, but upon trying to print some reports afterwards, they would just hang and not come up. So I did have to stop and re-start that Service, and then the reports worked.
