Once you've used Windows 8 for a while, you'll start to have more and more files, such as music, photos, and documents. It may sometimes be difficult to find the exact file that you want. You may even have trouble finding a specific app, since Windows 8 has moved everything around. Luckily, there is a built-in search feature, which can help you find files, apps, or almost anything else on your computer.
You can select different search options to help find specific files and settings. Just click the drop-down arrow above the search box, and then select the desired option:
If you're on the Desktop, you will first need to press the Windows key to switch to the Start screen, and then type what you're looking for.
If you're using a tablet without an attached keyboard, you can search by swiping in from the right and then selecting the Search charm. You can then type what you're looking for.
