Open the Network and Sharing Center control panel. (Go to the Start menu, select Control Panel.
If categories are shown instead of individual control panels, either select "Small Icons" from the "View by:" drop down menu in the upper right or select the View network status and tasks link under the Network and Internet heading.)
Next, in the left-hand pane, click on the Change adapter settings link.
For each network connection listed, right-click on the connection and select Properties. (You may be asked to supply an administrator password or to confirm that you wish to make changes to your computer's settings; do so if asked.)
Click on the Sharing tab and make sure the checkbox next to "Allow other network users to connect through this computer's Internet connection" is not checked, as shown to the right.
Click OK to save the setting.
