First off, what is MinWin? Basically itís the very basis of Windows, you need to think of it as the core of Windows. MinWin contains pretty much everything that Windows needs to boot and run independently, such as the Windows NT Kernel, memory manager, networking and drivers etcÖ

So whatís the big deal about this MinWin technology? Well we first started seeing MinWin playing a prominent part in Windows 7, but now it appears that itís going to be playing an even bigger role in Windows 8. Windows 8 appears to have in excess of 6,000 references to MinWin, which is 60 times more than the 100 references or so that can be found in Windows 7.
