Windows Vista activation via a spoofed KMS server is already an established method of circumventing the protections of the operating system. The Windows Vista KMS activation workaround
involves the use of a spoofed public KMS server, self-build KMS host or KMS local activation server VMware VM image and mini KMS virtual machine image, and it is a crack destined for Windows Vista Business and Enterprise. However, after it has been rebuilt to work on Vista Ultimate, hackers have adapted the KMS server crack to function on Windows Vista Home Basic and Windows Vista Home Premium.
The crack is actually a combination of the Vista Frankenbuild activation and the KMS workarounds. However, although it appears sophisticated, it is not. And furthermore, it is useless because Microsoft has already taken the necessary measures to throw Vista copies activated in this manner into Reduced Functionality Mode.
Windows Vista Ultimate copies activated with the Frankenbuild - KMS method are actually stripped down of features to the level of Vista Business or Enterprise, depending on which files are used for the Frankenbuild workaround. However, there are no details available on the process that strips Windows Vista Ultimate of features, and adds characteristics to Home Basic and Home Premium in order to obtain the Business and enterprise editions.
The fact that this crack emerges after Microsoft has already updated the WGA mechanism in order to tackle the issue is a clear indication that it is a method to spread malware more than anything else. Users that choose to illegally activate their Vista copies this way will not only not have access to any updates from Microsoft, but also risk exposure to attacks by downloading the files necessary for performing the crack.
