What is OEM Partition?
The Original Equipment Manufacturer (OEM) partition is a volume that contains system recovery programs, factory restore data, and diagnostic tools (in Dell PC), etc. It is used when you restore or reinstall Windows with the OEM disk or from BIOS. Different manufacturers specify different activate keys. For example, you can access HP OEM partition with F9 while you need to press F12 at power-up to enter Dell OEM. When your system corrupts or gets slower, you can easily go back to the factory installation with this partition. In most cases, the OEM partition occupies less than 100MB of the hard drive. Some computer manufacturer like HP displays this OEM partition with drive letter yet some hide this partition and it cannot be viewed in Windows Explorer. When it comes to OEM product key in a large amount of computers, sysprep is necessary. Also, one can delete an OEM partition if he finds it is useless.
