The search and organization features help you locate files, e‑mail messages, and other items on your PC. To find a file or program, start typing in the Start menu search box.

You can put your computer to sleep using the power button on the Start menu or the computer's power button. Your computer automatically saves your current session to memory and enters into a very low power state. It also saves your session to the hard drive, so you can access it even if the memory loses power. When you're ready to resume using your computer, just press the power button on your computer and your last session appears.
