Microsoft has been pushing Windows 7 as greener than Vista or XP, designed with a variety of energy-saving options for both IT administrators and end users. In an interview, Rob Bernard of Microsoft, insisted that the company’s newest operating system will come with environmentally friendly features baked into its infrastructure, creating greater energy efficiency (and a smaller carbon footprint) than Windows Vista or Windows XP. “Windows 7 is the first [Microsoft] operating system to operate at this granular level” of control over energy-saving options, Bernard said. For example, “the server and client interaction allows IT [departments] to run a power-efficiency diagnostics chart” and then use that information to adjust PCs for optimum operation. IT administrators can use Group Policy, WMI (Windows Management Instrumentation) and Powercfg.exe, a command-line power management utility, to centrally manage power settings, said Bernard.
