Windows 7 is a computer operating system released by Microsoft in 2009. Windows 7 was initially meant to be an improvement to the Windows Vista program that was released in 2007.
Windows 7 offers users a more streamlined and efficient operating system than was previous available in Vista. The new system allows for use with multitouch systems, meaning that you can use it along with the touchscreen products that you couldn't with Vista. Outside of the operations themselves, the Windows 7 version got some visual upgrades as well. The toolbars were upgraded so that things could be pinned to them and reordered.
