Windows Easy Transfer was a specialized file transfer program developed by Microsoft which allows users of the Windows operating system to transfer personal files and settings from a computer running an earlier version of Windows to a computer running a newer version.
Windows Easy Transfer was introduced in Windows Vista and is included in the Windows 7, Windows 8, and Windows 8.1 operating systems. It replaces the Files and Settings Transfer Wizard included with Windows XP and offers limited migration services for computers running Windows 2000 Service Pack 4 and Windows XP Service Pack 2. It does not transfer applications, only files and most settings.
The Windows Easy Transfer program was discontinued in Windows 10. Microsoft has chosen to provide a free version of Laplink's PCmover Express as an alternative to WET. End users also have the ability to upgrade to PCmover Professional (a paid version) which allows the transfer of applications as well.
