Extreme Tech wirtes:
In the seven months since Windows 7 made its appearance, it's already helped bury some of the bad will generated by its immediate and underloved predecessor, Windows Vista. We were a little bit skeptical at first about whether it was worth buying, but we've really come to appreciate its features, from increased speed to DirectX 11 support, as well as its overall attractiveness and ease of use.
Of course that doesn't mean it can't be improved a bit more in certain areas. Sure, keyboard and mouse shortcuts are nice, but you can only get more thorough personalization—like changing the look of the logon screen, the Taskbar, or even Internet Explorer 8's title bar—by digging deeper—into the Registry.
