Those are the basics, but there's still a lot to know. Here are 10 tips for performing useful tasks in Windows 8 that you might never discover on your own. Tasks can be carried out using touch or mouse and keyboard.
1. Returning to the Start screen: It's easy to lose your way in Windows 8 when you're just learning it, and finding the Start screen can help re-anchor you. To find it using a touch screen, swipe out the Charms bar on the right and press the Start charm. With a mouse, click the bottom-left corner screen. You'll know it's ready for the click when a tiny image of the Start screen pops up. On a keyboard, press the Windows key.
2. Organizing the Start screen: The Start screen is made up of a large number of tiles, so separating them into categories makes it easier to find the ones you want. Drag tiles either with a finger or using a mouse and dropping related tiles near each other.
3. Naming groups of tiles: Zoom out on the Start screen to get an overall view of the Start screen tiles. This can be done using a two-fingered pinching gesture or clicking on the minus button in the lower right. Find the group you want to name, right-click on it and choose Name Group, type the name and press Enter. Or touch the group, choose Name Group and type in the name.
4. Pinning tiles: Not all applications are displayed on the Start screen. To add one, right-click or touch a blank spot on the Start screen and click or touch All Apps when it appears on the bottom. Right-click or touch the app you want to pin, then click or touch Pin to Start.
5. Displaying administrative tools: Right-click the mouse in the lower left corner. Or press the Windows key + X and the tools menu appears in the lower left. Or, while on the Start screen, press the Windows key + I, select Tiles, press Enter, press the space bar to change Show Administrative Bar to Yes. Administrative tool tiles will be pinned to the extreme right of the Start screen. Or swipe out the Charms bar, touch Settings, touch Tiles, flip the switch to Yes.
6. Search: In Windows 8, the Search charm can be used to search the system or, if it is invoked while in an application, to search the application. To search, access the Charms bar, choose Search and type in the search term. If you want to search the Start screen, just start typing your search term on the Start Screen. After your first keystroke, a search window appears. It will be searching apps by default, so if you want to search something else, you have to press or click on it.
7. Switching from app to app: When you have more than one app open, click in the upper right to reveal thumbnails of all active apps and click on the one you want. With touch, swipe out from the left side of the screen then back to the left side again without lifting your finger. That will reveal the thumbnails (this display is called the Switcher). Press the one you want.
