This is a brand new, factory sealed package of Microsoft Windows 8.1 full version. It is the full retail version--NOT Academic, OEM, Not For Resale, Trial, Promotional, or Upgrade. This is exactly what you would buy in major retail stores and online sellers. The Microsoft SKU is WN7-00578. The installation DVDs are included. 

Please Note: This listing is for 1 sealed package. The picture shows multiple quantity because I want to show all sides of the package.

Easier access to your favorite apps and key controls

• Power and Search buttons on the Start screen. These buttons appear in the upper-right corner of the Start screen next to your account picture. You'll be able to quickly and easily shut down your PC or search for things right from Start. (Some types of PCs don't have the Power button on Start. You can shut down your PC using the Power button in the Settings charm instead.)
• All open and pinned apps appear in the taskbar. If you like using the desktop, you'll see both desktop apps and apps from the Windows Store in your taskbar when they're running. You can also pin any app to the taskbar so you can quickly open or switch between apps from the desktop. 
• Access the taskbar from anywhere. When you're using a mouse, you can see the taskbar from any screen, including Start or a Windows Store app. Move your mouse pointer below the bottom edge of the screen to show the taskbar and then click an app to open or switch to it.
• Go to the desktop when you sign in, instead of Start. If you spend more time in the desktop, you can sign in (boot) directly to the desktop instead of the Start screen. And if you want to sign in to Start instead, you can change this setting at any time.

More familiar mouse and keyboard options

• The Minimize button, Close button, and taskbar are more available with your mouse. Your mouse works more consistently anywhere in Windows. Move your mouse to the top of the screen to see Close and Minimize buttons in any app. Move your mouse down to the bottom of the screen to see the taskbar from anywhere in Windows.
• Right-click an app tile to see more options. If you're using a mouse and you right-click a tile on Start, you'll see a context menu next to the tile that shows what you can do with the tile.

Simpler to find new apps

• Discover apps in new ways. The Windows Store is pinned to Start and to your taskbar by default, so you can easily discover new apps. When you use the Search charm, Bing Smart Search includes apps in the suggestions and the search results.
• Remember what apps you recently installed. After you install new apps, Start includes a message in the lower-left corner of the screen, pointing you to the Apps view so you can see what you recently installed.

More PCs and devices to choose from

• If you want to buy a new PC, Windows 8.1 runs on a wider variety of devices, so you'll have more to choose from, including budget-friendly laptops and tablets.

Benefits for businesses

• For businesses customers, Windows 8.1 includes additional features that improve the compatibility of Internet Explorer, extend policy settings for mobile device management, and more easily install first-party apps for easier deployments across businesses.
