On April 30, 2018, Microsoft released Windows 10 April 2018 update (Windows 10 V1803) which brought along a lot of new features and improved upon existing ones. Then, many of you choose to upgrade to this new operating system from the old version.

However, you may find the new 1803 version creates a new disk partition, for example, recovery partition or OEM partition. Typically, the partition refers to a recovery partition used by the Windows recovery environment or the original equipment manufacturer.

A drive letter is assigned, and it is visible in File Explorer as well as Disk Management. This is because Microsoft is aware that previously-hidden partition is improperly being assigned a drive letter after installing the April 2018 Update.

Then, you may look for solutions to fix the issue when Windows 10 1803 update creates a recovery partition. Take it easy! Do the following things now to deal with the question of the additional recovery partition or OEM partition.
