Windows 10 is out today! I have been using it on PC for awhile, and I think it is just dandy. If you want to give it a try just head here. With the Media Tool you will be able to upgrade the computer you just downloaded it on, or create a bootable flash drive or ISO for another computer. Just remember that if you are going to do a clean install to have you Windows 7 or 8 product key at the ready. Other than that have fun with your new OS!
