EM_Exec.exe
(Logitech)
Logitech MouseWare Tray icon program. This program displays a mouse icon in the System Tray. Right-clicking or double-clicking on the icon enables you to access the Control Panel Mouse properties or the MouseWare help.
Recommendation :
Once they have set their mouse preferences, most users never go back to them unless the mouse is changed. This Tray icon is therefore superfluous and simply adds to the System Tray clutter. Disable or Delete using Startup Manager. Note: In some cases disabling EM_EXEC prevents the scroll wheel or some of the additional mouse buttons (middle and fourth when present) or features (eg. smartmove) from working properly, in which case re-enable it.
