Windows 8.1

Windows 8.1 lets you work the way you want. Move easily from one thing to another by multitasking on any Windows PC or tablet. Pull up a Wikipedia article to settle a debate with the friend you're on Skype with. Or play a music video while polishing your resume. Depending on your screen size, you can see up to four apps at once.

Bing Smart Search gives you results from your PC, your apps, and the web. Results are in a clean, graphic view that lets you do things and launch apps right away. Find a song and start playing it, or find a video and watch it right away.

It goes where you go.

Use your Microsoft account to sign in to any of your tablets or PCs 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 OneDrive
