Microsoft to offer XP-to-Windows 7 upgrades
InfoWorld | at | by Mike
Microsoft confirmed Tuesday that it will sell what it calls "upgrades" for Windows 7 to users running the aged Windows XP operating system.
Although Microsoft Tuesday spelled the six planned versions of Windows 7, it declined to provide pricing for them, or for the XP upgrade licenses.
Typically, an operating system upgrade offers users the choice between an in-place migration of the machine -- including installed applications and all data -- and a fresh installation, which overwrites the hard drive's contents. When Microsoft launched Windows Vista in January 2007, for example, it offered people then running XP those upgrade paths.
