To help avert criticism, Microsoft and its retail partners will temporarily offer steep discounts on the Upgrade versions of Windows 7 Home Premium and Professional only. Consumers who preorder these products online between June 26, 2009 and July 11, 2009 in the US and Canada will pay just $49.99 for Windows 7 Home Premium (Upgrade) (a $70 savings) and $99.99 for Windows 7 Professional (Upgrade) (a $100 savings). The deals will be made available at Amazon, Best Buy, and Microsoft, and at other participating online retailers. Consumers in Japan, France, Germany, and the UK can also preorder Windows 7 for similarly short time frames, though the exact dates vary. Microsoft also announced that it would allow consumers who purchase a Windows Vista-based PC between June 26, 2009 and January 31, 2009 to receive a free copy of Windows 7. Called the Windows 7 Upgrade Option Program, this program is global and completely free. Microsoft hopes it will address the problems caused by Windows 7 not shipping in time for the back to school PC selling season, which is currently underway.
