Normally, you should see a tab labeled My Mouse where you can customize your MK550 Mouse using the Logitech SetPoint Mouse and Keyboard Software. If this tab isn't displayed, you'll need to re-install SetPoint.

NOTE: The mouse that came with your MK550 Desktop will display in SetPoint as Wireless Mouse M510. If you have more than one Logitech mouse and the M510 isn't currently displayed, click the down arrow next to the current product name and select it from the drop-down menu that displays.
