Last computer was bought in 2008, windows vista! I got a work computer with windows 8 not too long ago and hated everything about windows 8. No start button, the whole "app" crap is ridiculous for a computer. switching between excel files and open pdf's was so stupid. Got the windows 10 download for free from microsoft....my guess is so many people complained and windows 8 is such garbage that they needed to fix it. The download was about 3 gb, i have fast internet so the whole process took around a half hour. I LOVE IT. Start button is awesome, everything is there. Layout is great. The notifications button on the bottom right gives you buttons for network, location, bluetooth, brightness, all kinds of good stuff. It flat out works. I have SSD so my bootup is 10 seconds anyway. My favorite windows i've ever used. i really like the search function as well, since you can choose to search your computer, or web, or both, and it displays the information is a very good way. Good work microsoft.
