Windows 8 can scrub data from disk, but not up to tough security specifications
Windows 8 includes a reset function that restores the operating system to a clean state and scrubs data applications from the disk, but falls short of making that data unrecoverable, according to Microsoft.
The operating system, now available as a developer's preview, can also refresh itself, restoring the operating system to its original state while also saving data and applications, according to the Building Windows 8 blog.
