Windows kernel sucks, a total waste of money. It's like retards made it. Especially after windows xp, the whole thing totally broke up, it was just advance in graphics which just wasted processor traffic and graphics card memory. Linux on the other side is well-made, and as an open source thing, is being improved every day, so it's mostly secure, reliable and flexible. I choose slackware linux with KDE environment, along with a freeBSD partition for hardcore applications. Unfortunately, average users prefer windows because they are easy to use and support half the basic stuff. But windows is a pile of shit to my opinion, full of bugs, glitches and immature programming. The only thing keeping them from releasing their kernel's source code is shame.
