Change mouse settings
Have a look at MS's site for a few minutes and that should help you out with mouses settings and configuration
Open Mouse by clicking the Start button , clicking Control Panel, clicking Hardware, and then clicking Mouse.
Click the Pointer Options tab, and then do any of the following:
To change the speed at which the mouse pointer moves, move the Select a pointer speed slider towards Slow or Fast.
To make the pointer work more accurately when you're moving the mouse slowly, select the Enhance pointer precision check box.
To speed the process of selecting a choice when a dialog box appears, select the Automatically move pointer to the default button in a dialog box check box .
Please remove any past old mouse drivers from logitech and anything else to make sure your current mouse driver does not have a problem while operating and moving.
Never played WOW but check in it's game settings and look under advance ones to properly calibrate it and set it to your liking.
