In systems using the Windows 7 platform, the operating system creates a hidden partition at the time of its installation. The hidden partition is not visible under My Computer as no letter is assigned to it. This partition of around 100 to 200 MB capacity can be accessed through Disk Management. This hidden partition created by Windows 7 contains the Recovery Environment WinRE that is of vital importance, because it allows recovery of the system if any problem is encountered at the time of start up. The hidden partition should not be removed, to prevent loss or damage to the system files, and as well as of the Master Boot Record.
