Microsoft currently is introducing Windows Anytime Upgrade(WAU) for Windows 7 to fit different needs from consumers over time.

Windows 7 Home Premium to Windows 7 Ultimate: $139.99
From October 22th,consumers could get Windows 7 retail packages which contains a upgrade key for WAU purpose.People who live in the 13 countries(Australia, Belgium, Canada, France, Germany, Italy, Japan, the Netherlands, Spain, Sweden, Switzerland, the UK or the US) are able to upgrade from Windows online store while others may be only get that at a store near you.
Microsoft also announced that Windows 7 Home premium edition will have family pack which will provide 3 licenses at $149.99.That’s great!It means family users only need to buy that pack and let this advanced OS run on 3 PCs at home with a quite reasonable price.
I just wonder whether the price could be a bit cheaper in Asia.
