The ninth chapter of our series presents the second part of the evolution of one of the most troubled development cycles in Windows history. After its development was reset in August 2004, Windows Longhorn would have lots of the major features slated for release either postponed or canceled, as Microsoft was trying to put more emphasis on stability and performance. However, unfortunately, even though Windows Vista would bring radical new changes to the Windows architecture, all of this came at cost, since the system requirements of the new OS were much higher. As such, Vista was plagued from the beginning with negative reviews criticizing its slow performance and driver issues.
