* Boot time: win7 48 sec. win8 10 sec.

In Windows 7, you didn’t have the option to make virtual drives to use the ISO image’s content but Windows 8 allows you to create a virtual drive to mount the ISO image so that you can easily use it just like a normal DVD.

Customer can also choose taskbar on both screens with different icons on each monitor. Moreover, you can play with background images as well by changing it separate on each monitor. Such support is not available with Windows 7 operating system.

Windows 8 store offers both desktop apps and ecosystem for developers. On the other hand, Windows 7 OS is missing all t
