Few weeks ago a leaked build of Windows 8 provided hints of an "Push Button Reset" feature, the first screenshot of this developmental feature is now available thanks to Win7China.
The new "System Reset" feature will allow users to go-back to default Windows 8 install removing all installed applications and restoring to default OS settings. This feature will definitely come handy saving time in-cases where Windows re-installation is the only option left keeping user files and settings intact.
