Win7 removes the program that comes with it but is not commonly used

1 Double-click the “Programs and Features” option in the “Control Panel” and then click the “Open or Close Windows Function” option on the right side of the figure. A “Named” function will pop up. In the window, you can see that the checkboxes to the right of many system components are selected.
2 Uncheck the system components that are not used according to your needs (such as "XPS Service", "Media Function", "Play", "Remote Differential Compression", etc. );
3 Finally click on the "OK" button and follow the prompts to restart the system.
4 After the above steps, those system components that have just been unchecked have been successfully deleted.
Note:
1 For the "Windows Search" check box, you must not uncheck the box; if you cancel, you can not use the search function that comes with the Win7 system to search for file resources on the hard disk.
2 If you use a system component that has been deleted later, you can check the corresponding check box in the window and restart the system to complete the reinstallation of the system components.
