Chapter 1. Desktop & Start Menu

These days, the graphic user interface (the colorful world of icons, windows, and menus) is standard. Mac, Windows, Chrome OS, Linux—every operating system is fundamentally the same, which is to say a very long way from the lines of typed commands that defined the earliest computers.

Windows 10 restores the desktop to its traditional importance, following a weird three-year detour into “what the heck” land known as Windows 8. The desktop is once again your only home base, your single starting point. It’s the view that greets you when the computer turns on, and it offers all the tools you need to manage and organize your files.

Herewith: a grand tour of the state of the art in computer desktops—the one in Windows 10.

The Lock Screen

When you turn on a Windows 10 machine, you know right away that you’re not in Kansas anymore. The first thing you see is a colorful curtain that’s been drawn over the computer’s world. It’s the Lock screen (Figure 1-1).

The Lock screen serves the same purpose it does on a phone: It gives a quick glance at the time, the date, your WiFi signal strength, the weather, and (on laptops and tablets) your battery charge. As you download and install new apps, they can add informational tidbits to this Lock screen, too.

The point is that sometimes you don’t really need to wake the machine up. You just want to know what time it is.

The Lock screen can also give you instant access to your Camera and Skype apps (Camera and Skype). You might want to take a picture or answer a call without having to go through the red tape of fully logging in.

You can control which apps are allowed to add information to the Lock screen in Settings (like the weather report shown here).You’re not stuck with the Lock screen photo as Mother Microsoft has installed it, either. You can change the picture, if you like, or you can eliminate it altogether. Chapter 4 has the details.

When you do want to go past the Lock screen to log in, there’s nothing to it. Almost anything you do that says, “I’m here!” works:

Touchscreen: Swipe a finger upward. (Swipe downward to jump into Camera mode.)

Mouse: Click anywhere. Or turn the mouse wheel.

Keyboard: Press any key.

The Lock screen slides up and out of the way, revealing the Login screen (Figure 1-2, top).

TIP

You can change the photo background of the Lock screen, make it a slideshow, or fiddle with which information appears here; see Customizing the Lock Screen. You can even eliminate the Lock screen altogether—after all, it’s an extra click every time you log in. For step-by-step instructions, see “Eliminating the Windows 10 Lock Screen,” a free downloadable PDF appendix on this book’s “Missing CD” page at www.missingmanuals.com.

The Login Screen

As in any modern operating system, you have your own account in Windows. It’s your world of files, settings, and preferences. So the second thing you encounter in Windows 10 is the Login screen. Here, at lower left, you see the name and photo for each person who has an account on this machine (Figure 1-2). Choose yours.

This is also where you’re supposed to log in—to prove that you’re you. But logging in no longer has to mean typing a password. One of Windows 10’s primary goals is to embrace touchscreens, and typing is a pain on tablets.

Therefore, you can log in using any of these techniques:

Just look at your screen. On laptops or tablets with Intel’s RealSense infrared cameras, facial recognition logs you in.

Swipe your finger across the fingerprint reader, if your computer has one.

Put your eye up to the iris reader, if your machine is so equipped.

Draw three lines, taps, or circles on a photo you’ve selected (Figure 1-2, top).

Type in a PIN you’ve memorized.

Type a traditional password.

Skip the security altogether. Jump directly to the desktop when you turn on the machine.

See Chapter 19 for instructions on setting each of these up.
