UPDATE: Thanks to Dan Edwards at Pact-One for this clarification. Windows 7 is no longer being preinstalled in new home PCs but it is available as a special order from Dell. You will be able to order a computer downgraded to Windows 7 Pro for at least 1 year or until Windows 10 is released whichever comes first. Windows 7 Home, Home Premium and Ultimate can no longer be ordered.
If you want to buy a PC with Windows 7 Home Basic, Home Premium, or Ultimate preinstalled, you’d better buy it today. As noted earlier this year, October 31 is Microsoft’s cut-off date for OEM preinstalls of the consumer editions of Windows 7.

The biggest problem with this for dentists is that many of our primary legacy systems, like practice management and radiography have not been upgraded to use Windows 8 in an optimum manner.
