You can use Control Panel to change settings for Windows. These settings control nearly everything about how Windows looks and works, and you can use them to set up Windows so that it's just right for you.
Open Control Panel by clicking the Start button , and then clicking Control Panel.
There are two ways to find Control Panel items:
Use search. To find a setting you're interested in or a task you want to perform, type a word or phrase in the search box. For example, type "sound" to find specific settings for your sound card, system sounds, and the volume icon on the taskbar.
Browse. You can explore Control Panel by clicking different categories (for example, System and Security, Programs, or Ease of Access), and viewing common tasks listed under each category. Or, under View by, click either Large icons or Small icons to view a list of all Control Panel items.
If you browse Control Panel by icons, you can quickly find an item in the list by typing the first letter of the item's name. For example, to find Keyboard, type K, and the first Control Panel item beginning with the letter K—in this case, Keyboard—is selected in the list.
You can also use the arrow keys (Up Arrow, Down Arrow, Left Arrow, and Right Arrow) to scroll through the list of icons in Control Panel.
