Wisptis.exe (\Windows\System32) -
This executable runs as a system service that provides pen-data collection for other components of the SDK. When a component needs to interact with the pen (for example, to collect ink or to detect gestures), this executable is spawned as a service to communicate directly with the input device. On a Tablet PC, Wisptis.exe interacts with the digitizer, whereas on a desktop it interacts with the mouse as well. The executable’s name is an acronym that references an outdated internal name for the team that developed it (Windows Ink Services Platform Tablet Input Subsystem).
I haven't been able to figure out what can be disabled in services.msc to prevent this file from loading automatically, but you could try running "tasklist /svc" from the command line. Perhaps, the output might help you to figure out what the name of the service is.
