With Windows 7, Microsoft introduced a really unique and beautiful appearance for the operating system. Windows Vista already had some features like transparent window frames with glass (blur effect) but Windows 7 introduced a glass taskbar and a glass Start Menu which follows the Aero color. They were very well received by most users. With Windows 8, Microsoft removed the glass effect from window frames and the blur effect from the taskbar. In Windows 10, the appearance has become even less 3D, minimalistic and uses completely flat colors without any gradients. Many users are missing the good old look of Windows 7. Let's see how to get the Windows 7 theme in Windows 10.
