A new “Action Center” interface was also added to provide an overview of system security and maintenance information, and tweaks were made to the User Account Control system to make it less intrusive. Other new features were added to the operating system, including libraries, the new file sharing system HomeGroup, and support for multitouch input.
Windows 7 continued improvements on Windows Aero (the user interface introduced in Windows Vista) with the addition of a redesigned taskbar that allows applications to be “pinned” to it, and new window management features. Windows 7 was primarily intended to be an incremental upgrade to Microsoft Windows, addressing Windows Vista’s poor critical reception while maintaining hardware and software compatibility.
