Windows Store
You have much easier access to the Windows Store where you can buy free and paid apps. While many of these are touch-based apps, you’ll also find a nice selection of mouse-friendly ones, too.
Built-In Antivirus
After you install Windows 8, you will automatically have Windows Defender on your computer, which is a hearty little antivirus program that offers ingoing and outgoing protection against malware.
Automatic Cloud Storage
Everything from your address book to your system settings can be stored in the cloud. Then you can access it on any Windows 8 PC. You can get your personal PC experience on your home computer, work laptop, and even at a friend’s house if they have a Windows 8 machine.
System-Wide Search
It’s a lot easier to hunt down that lost MP3 with the faster, more responsive system-wide search available in Windows 8. The search also connects to the Internet, so it’s really your one-stop-spot for browsing on your computer.
