windows 10 is the Goldilocks version of Microsoft's venerable PC operating system -- a "just right" compromise between the familiar dependability of Windows 7, and the forward-looking touchscreen vision of Windows 8.
This new Windows, available as a free upgrade for existing Windows 7 and Windows 8 noncorporate users, is built from the ground up to pursue Microsoft's vision of a unified OS that spans all devices without alienating any one platform. It's an attempt to safeguard Microsoft's crumbling software hegemony, assailed on all sides by Google and Apple. And it's a vision of the future as Microsoft sees it, where a single user experience spans every piece of technology we touch. Welcome to Windows as a service.
Yes, this new OS is chock-full of fresh features. To name just a few: a lean, fast Internet Explorer
replacement called Edge; Microsoft's Siri-like voice-controlled virtual assistant, Cortana; and the ability to stream real-time games to your desktop from an Xbox One in another room. (And in case you're wondering: there is no "Windows 9" -- Microsoft skipped it, going straight from 8 to 10.)

The GOOD about the windows 10..
The new windows 10 bridges the gap between the PCs and tabs without alienating anyone...The new OS combines the best bits of old and new features into a cohesive pack..vth correcting all the misteps of windows 8 ..The upgrade process is much painless especially for the windows 7 n 8 users....
