I have an laptop for my personal use and it was running on Windows 8 in August 2015. After that in July 2015, Microsoft announced to launch an new operating system windows 10. It was an upgraded version of Windows 8. And they provided free upgrade for Windows 8 users. So I have upgraded my operating system. And after that I have seen many important and useful features in it. Its look and design was stylish and unique. New taskbar design added and sound driver not needed while u install this window. And running and processing speed was very fast. Video and audio quality was superb. And new look of screen shots and screen lock panel. So after seeing all these features I love this operating system so much. I like it.
