Get a new touchscreen pc and you can still work with a mouse, keyboard, and the windows desktop the way you always have. Use virtually any printer. Programs that work on windows 7 work on windows 8.1. All the basics, from startup times to security, are better than ever.

touchscreens, apps, and online storage
With apps from the windows store, and new ways to tap, swipe, and zoom around, windows 8.1 gives you a world of touchscreen entertainment of all kinds. And with skydrive—free online storage that's built into windows 8.1—your files are always with you, from any of your pcs or devices.

The familiar made better
The desktop you're used to—with its familiar folders and icons—is still here. And not just still here, it's actually better than before, with a new task manager and streamlined file management. And you can always get to your desktop—and back to your start screen again—with a tap or click.

Programs
Use them the way you always have. Word, excel, powerpoint, and other programs you count on work the way you're used to. Use a mouse and keyboard and organize your stuff in folders on the desktop.

Security
Windows defender and windows smartscreen can help guard your pc against viruses, spyware, and other malicious software in real time. Family safety gives your kids some independence while still keeping tabs on them.

Mouse and keyboard

• You can use a mouse and keyboard to work on your windows desktop the way you always have. And things you do with touch, like using apps from the windows store and getting around on your start screen, can also be done with a mouse and keyboard.
• Photos, news from friends, your favorite apps and sites—put what's most important to you on your start screen. Choose your colors and move stuff around until it's just the way you like it.
• Your favorite apps, sites, and people: make each one a tile you can resize, move around, and organize the way you want. Some tiles animate with the latest information so you see live updates at a glance. Get status updates, weather forecasts, and tweets as soon as you sign in.
• Your lock screen displays a slide show of your favorite photos. Plus, you can answer skype calls, and take photos before you even unlock your pc.
• Instead of typing a password, you can unlock your pc by drawing shapes on a picture with your finger or mouse. Three taps or clicks on your dog's nose? Tracing the smile of your toddler? The choice is yours.

search once, go anywhere
Bing smart search gives you results from your pc, your apps, and the web. Results are in a clean, graphic view so you can quickly get to what you're looking for. (certain features unavailable in some regions.)

See more, do more
Windows 8.1 lets you work the way you want, and flow smoothly from one thing to another. Pull up a wikipedia article during a chat with a friend to settle a debate. Play a music video while polishing your resume. Depending on the size of your screen, you can see up to four apps at once.

Your windows, everywhere

• It goes where you go.
• Use your microsoft account to sign in to any of your devices running windows 8.1, and you'll see the same layout, apps, and settings. Signing in with your microsoft account (which is simply an email address and password of your choice) also gives you access to a world of apps from the windows store, and lets you save, view, and edit your documents and photos online with skydrive.
