window 8.1

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.

One view of everything

• When you're working on the familiar desktop, all apps you've opened will appear in your taskbar at the bottom of the screen. This includes both apps you opened from the desktop and apps from the Windows Store you opened from your Start screen.

Make it yours

• Start screen Tiles - Personal lock - screen Picture - password
• 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.  

Multi task with apps

• 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. 

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.)

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 OneDrive.

OneDrive

• Your files are always with you
• OneDrive is free online storage that's built into Windows 8.1. Save documents, photos, and other files to OneDrive automatically, and get to them anytime, from any of your PCs or devices. And you can use OneDrive to protect your files if something happens to your PC.
• You can also use OneDrive to share and collaborate with others, and see your stuff on mobile and non-Windows devices.

Internet Explorer 11

• Fast, fluid, built for touch
• Internet Explorer 11 is built for touch—now with larger tabs, simpler controls, and fluid response to gestures. Internet Explorer harnesses the power of hardware acceleration, so sites load faster and browsing’s smoother.

Skype

• Video, voice, and instant messaging
• The always-on app that makes staying in touch with all your contacts easier than ever. Keep in touch with video and voice calls and instant messaging, all from one app. Call any phone quickly and easily. All Skype-to-Skype video and voice calls are free, and your messages are delivered straight to you no matter what you're doing. Snap Skype left or right and do more while you IM, video call, or keep an eye on your home screen. 

Windows Store

• Load up on apps
• Open the Windows Store right from your Start screen to browse and download apps for cooking, photos, sports, news, and a lot more—many of them free. Sort by price, rating, and category. Find old favorites and hot new apps.
