Lace Whitney of CNET: "Windows 8 will provide a refresh option that can automatically restore your PC to a clean state without erasing all your data and customized settings. Due to appear in the Windows 8 beta that will debut next month, the refresh option makes good on Microsoft's earlier promise that it would give users an easy way to restore Windows in the event of a problem.
As described in yesterday's Building Windows 8 blog by Desmond Lee, a program manager on Microsoft Fundamentals team, the new OS will actually offer two ways to bring Windows back to factory condition:
• The refresh option will keep all personal data, important settings, and Metro style apps, and then reinstall Windows.
• The reset option will securely remove all data, settings, and applications, and then reinstall Windows."
