Start menu
Windows Vista and its successors added minor changes to the menu. Prior to Windows Vista and Windows Server 2008, the Start menu consisted of a group of menus and sub-menus that cascaded and expanded, obscuring the initially visible portions of the screen beneath them. In Windows Vista, however, cascading menus were replaced by a sliding window in the left pane of the Start menu. Whenever the All Programs item is clicked, the contents of the left pane slide off the left edge of the Start menu, and the All Programs menu slides in from the right edge of the left column. This menu presents a tree view of its hierarchy that expands towards the bottom, with a vertical scrollbar whenever needed. Also added in Windows Vista is a "Search" box that allows users to search for the Start menu shortcuts or other files and folders. The search box features incremental search: If indexing is not turned off, the search box returns results on-the-fly as users type into it. Since the found items can be immediately opened, the Start menu search box partially replaces the function of the Run command from previous versions of Windows. The Run command can also be added separately to the right column in the Start menu. In Windows 7 and Windows Server 2008 R2, the search results pane covers both columns of the Start menu. The search box is extended to support searching Control Panel items. The right column in Windows 7 links to Libraries instead of ordinary folders. Most importantly, however, items on the Start menu support "Jump lists" through cascade buttons on their right. Unlike prior versions, the ability to revert to the "Classic" Start menu design is no longer available.
