Mount Hidden partitions without Unhiding it

Most computers have a hidden recovery partition which contains recovery files required to repair or restore your computer.
These partitions appear as OEM Partitions in Windows Disk Management. Unfortunately these Hidden OEM Partition cannot be mounted with a drive letter using Windows Disk Management. Right clicking on the hidden partition does not give any options.

So if you want to view the contents of this Hidden OEM Partition, you will have to unhide it using a Partition Management tool like Bootice. However unhiding and hiding it maybe cumbersome and if the partition is not hidden properly the recovery tools may not work properly.

Fortunately there is simple way to mount such hidden OEM partitions without unhiding it using Partition Management tools.

MountStorPE short for Mount Storage PE is a tool which is primarily used in Pre-Installations Environments (PE) to assign drive letters to USB disks connected after system boot. An interesting feature of this tool is that it assigns drive letters and mounts hidden partitions.
