25, March 2017: Reinstalling Windows 7 may not lead to permanent data loss. Lost files can be recovered with data recovery software unless the lost files are overwritten. If you want to recover lost files after reinstalling Windows, please stop using the hard disk and make sure you do not save any data to the hard disk, as this would cause data to be overwritten and permanent data loss. Once the data is overwritten, it is little chance to recover lost files after reinstalling Windows by any data recovery software.

Windows 7 was primarily intended to be an incremental upgrade to the operating system intending to address Windows Vista's poor critical reception while maintaining hardware and software compatibility. 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. Other new features were added to the operating system, including libraries, the new file sharing system HomeGroup, and support for multitouch input. 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. Windows 7 also shipped with updated versions of several stock applications, including Internet Explorer 8, Windows Media Player, and Windows Media Center.
