Windows 8 Reset and Refresh options shown off!

Windows 8 is becoming more and more like the mobile counterpart.  Windows 8 will offer a pair of similar features; ‘Reset your PC’ will allow you to remove all personal data, apps, and settings from the PC, and reinstall Windows, while ‘Refresh your PC’ enables your to keep all personal data, Metro style apps, and important settings from the PC, and reinstall Windows. This seems very convenient, especially for those who have often been bugged by crowded and laggy machines.
