Windows 10 1803 Update Creates a Recovery Partition

“I updated my Cubei7 Book to Windows 1803 from 1709 last week. Since the update, I keep getting the message “Low Disk Space on Drive: E”. From using Mini Tool Partition Wizard and found that drive is the recovery partition. There is only 47.2 MB out of the 450 MB. Before updating, I never saw this drive before in Windows Explorer. ” social.technet.microsoft

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.

Besides, it occupies disk space (at least virtual). In certain situations, Windows shows you a warning saying the disk is full after a startup. What’s more, you may find it is almost nearing 100% when checking disk utilization in the Task Manager. This degrades system performance.

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.
