For those looking to shave a few pounds off the price of the next Windows 7 Home Premium edition, there is apparently a loophole involving the upgrade version of Windows Vista Home Premium.

According to the terms and conditions at Amazon, buying an eligible copy of Windows Vista from Amazon.co.uk between 26th June and 15th October 2009 are eligible for a free copy of the equivalent version of Windows 7 when it is launched.

In addition, Amazon's FAQ section says that "At present in the EU, all versions of Windows 7 (Home Premium, Professional and Ultimate) are the full product.s This means that to install Windows 7, you do not need any previous version of Windows installed on your computer."
