It’s the Windows you know, only better
 
 
You’re already an expert
 
Windows 10 is so familiar and easy to use, you’ll feel like an expert. The Start Menu is back in an expanded form, plus we’ll bring over your pinned apps and favorites so they’re ready and waiting for you. 

It starts up and resumes fast, has more built-in security to help keep you safe, and is designed to work with software and hardware you already have.
The web that works the way you do
 
Windows 10 comes with Microsoft Edge, an all-new browser that’s built to give you a better web experience. Write2 or type notes directly on webpages and share them with others, read online articles free of distraction, and save your favorite reads for later access. And with Cortana3 enabled, you get instant access to key actions—like making reservations or reading reviews—without leaving the page you’re on.
Multi-doing helps you get to “done“ faster
 
Easily snap up to four apps in place and see all open tasks in a single view. You can even create virtual desktops when you need more space or want to group things by project.
Windows Store is your one-stop shop
 
Introducing the new Windows Store, a unified shopping experience across every Windows 10 device. Browse the store on your PC, tablet, or phone and easily purchase great digital content including apps, games, music, movies and TV shows.
It’s the most personal Windows yet
 
Meet Cortana, your truly personal digital assistant
Cortana works across your day and your devices to help you get things done. By learning more over time, Cortana becomes more personal and useful to you. Cortana’s also best at reminders, delivering them at the right time and place so you forget less and can do more.
