LWemon.exe
(Logitech)
Logitechs Wingman Profiler Joystick System Tray utility which shows up as a large W. It allows the user to customise the Wingman Joystick behaviour. If you end this background task, a warning message is displayed stating that the joystick may cease to function properly, however users report no ill effects as a result of doing so. The reason this is is that most gamers use the games joystick configuration to set up their buttons. If you use the Wingman software, on the other hand, then your settings will not take effect unless you have LWEMON running in the background.
Recommendation :
If you always use the games own joystick configuration setup, then disabling LWEMON is fine. Otherwise, if you use the Wingman software, then you will need to leave LWEMON running the background.
