A few weeks ago several screen shots of early Windows 7 builds began circulating but many called it into question because it looked like Vista. It more than looked liked Vista, the version number was similar to the one used in Vista. Thats because it was basically Vista but not completely. Microsoft has said that the final release of Vista SP1 will include a new operating system kernel but thats probably not the minWin kernel which is to be part of Windows 7 final. It does appear that Windows 7 includes some new features and an improved Vista kernel but not a completely new kernel. In fact the Milestone release of Windows 7 isnt even a full operating system, it requires Vista as a base to install. TGDaily managed to perform a review of the Milestone 1 release. Aero had to be enabled manually, the performance indexer also had to be updated manually and there were a few incompatibility issues which was attributed to early code. What was interesting is that the installer automatically created a dual boot system, one partition with Vista, one partition with Windows 7. The bad thing here is that it didnt even ask, it just did it. My guess is the final version will present the option of a dual boot, wipe and install over Vista or upgrade Vista to Windows 7. There is one point that TGDaily may have gotten wrong. Windows 7 M1 had memory usage of 500MB without anything else running. The author says, The system feels slightly faster than the regular Vista memory usage is at about 500 MB with no other software running in the background. Overall, the potentially new and much leaner kernel isnt there yet. I beg to differ, yes it is, at least partially. A fully booted Vista system without anything else running will use ~800MB - 950MB. Microsoft has not changed any other part of the operating system. The interface and the icons remained the same. Possible changes point to a Mac OSX dock and what appears to be a minimized application bar but these were not present in the build that was reviewed. Windows 7 will release at some point between 2009 and 2011, its so early in the build even a release year would be hard to pin down.
