Microsoft has announced that Windows 7 will will be on sale starting on October 22nd, 2009. It will be officially available in seven different versions, from the Windows 7 Starter, intended for netbooks and the like, all the way through to Windows 7 Ultimate, with Enterprise, Home and Pro versions along the way.
Microsoft said that those who purchase PCs running Vista between now and the Release Date will receive either a free or discounted copy of Windows 7. As with past similar programs, details on pricing will be up to individual computer makers, although Microsoft did say the upgrade program will apply to Vista Home Premium and higher-priced editions (meaning not Windows Vista Basic). The software maker has yet to announce pricing for the product.
