New Partitions Appearing on Disk 0 after Windows 10 Update

I recently upgraded Windows 10 to the spring update. Since that time there are two new partitions on Disk 0 (which is an SSD), one very small and active (labelled N), and one even smaller which is empty and unlabelled.  Disk 0 also contains my boot drive (C) which has lots of open space.

I am getting new messages that the N drive on my desktop machine is almost full.  But I don't use it and it appears to contains only three folders: Recycle.BIN, Recovery and System Volume Information.

If I look at Disk 0 through the Windows 10 Disk Management utility the small N drive is referred to as an OEM Partition, the unlabelled area is called an EFI System Partition, and the C drive is referenced as "Boot. Page File, Crash Dump, Primary Partition".  All three drives are said to be "Healthy" and both the N and C drive are NTFS.

I would like to go back to a single partition on Disk D, or at a minimum, eliminate the "almost full" messages for the N drive.  My inclination is to buy a partition management utility such as EaseUS to do that but I am being cautious given the nature of the problem and the consequences of screwing it up.

I would appreciate any suggestions on what is happening here and what I should do.  Thank you.

Usually these OEM drives contain some hidden boot data for data recovery tool set by PC vendor. Just remove the N drive letter from it and the messages will not appear again.

One more thing:  I just loaded EaseUS but did not make any changes.  The partition I am referring to as N above is labelled as "Unused Partition"  and other smaller partition which I mention above is called "EFI System Partition"
Removing drive letters does not hurt. Anything else can gi bad, so don't delete partitions.

Thanks.  Your comments lead me to more focused searches (such as the one above) and the solution.  I will delete only the drive letter and leave both of the partitions in question alone.
