Windows 10 has matured into a fantastic modern operating system and there's never been a better time to move up from Windows 7 or 8 to the latest OS. Or build your own brand new PC!

Windows 10 Professional includes features of Windows 10 Home, plus important business functionality for encryption, remote log-in, creating virtual machines, and more. Get fast start-ups, a familiar yet expanded Start menu, and great new ways to get stuff done, plus innovative features like an all-new browser built for online action and Cortana, the more personal digital assistant.

Windows 10 is designed to go with you seamlessly from one device to another. It's fast and responsive. You even get free chat or phone support from real people. With Windows 10, it's easier than ever to do great things.

Multi-task like a master with the ability to snap four things on the screen at once. Screen getting crowded? Create virtual desktops to get more space and work with just the items you want. Plus, all your notifications and key settings are collected on one easy-to-reach screen.

What was new in Windows 10, when it was released? The OS brought back the Start Menu, though with a twist: live tiles keep you up-to-date with the latest news while also providing an easy way to launch apps. (Don't worry if you prefer the Start Screen, it's still there and you can boot into it if you prefer.)

When you buy Windows 10 Professional, you'll be presented with the latest version which is now the May 2021 update. Your activation code will activate either the 64-bit or 32-bit edition of Windows 10 Professional.

Finally, remember Windows 10 Professional OEM is intended for installation on a new or clean PC only, ideal for building your own PC, getting Windows 10 installed on an old PC or simply starting from scratch or as a Windows operating system for your Mac either via Boot Camp or as a virtual PC.
