Windows 7 Leave the Homegroup

Leave the Homegroup
Homegroups are an easy way to network Windows 7 PCs, but if you don't use the feature then turning it off can save you a few system resources.
Click Start, type Homegroup, and click "Choose homegroup and sharing options". Click Leave the Homegroup > Leave the Homegroup > Finish.
Now click Start, type services.msc and press [Enter] to launch the Services Control Panel applet.
Find and double-click both the HomeGroup Listener and HomeGroup Provider service, clicking Stop and setting Startup Type to Disabled in each case, and the services won't be launched when you need reboot.
