The Windows 8 development team updated its blog today to explain how the company has optimized the way Windows 8 uses memory.

Our goal with Windows 8 from the beginning was to ship with the same system requirements as Windows 7. We know if we do even better that there are more resources for apps, even if we keep the published requirements the same. It is fun to think about what the "low end" hardware looked like in 2009 and how you can't even find things like 256MB memory modules anymore. We wanted to ensure that people running on Windows 7-era hardware would have the option to easily upgrade their existing machines to Windows 8 and take advantage of the functionality it has to offer. We also expect that many machines that predate the Windows 7 release will run Windows 8 based on the experiences we've had with older machines we intentionally keep in our performance test infrastructure.

An important task for Windows 8 was to make room for new functionality while looking for opportunities to reduce the memory consumed by existing functionality and consumed across the board. Windows 8 is tracking well towards meeting the goal we set ourselves.
