This does not happen when performing fresh Windows Install. Only happens when you perform update.
Even though the name was change from Recovery to OEM, the partition ID is still: DE94BBA4-06D1-4D40-A16A-BFD50179D6AC
Removing the Drive Letter is not enough. You need to set the correct Attributes for this partition to prevent Drive Letter assignment.
Open Admin Command and type:
diskpart
select disk # where # is the disk # of Windows
select partition 1
deltail par
You should get the result as follows:
If not, from diskpart, set the partition ID and Attributes:
set id=DE94BBA4-06D1-4D40-A16A-BFD50179D6AC override
gpt attributes=0x8000000000000001
NOTE: setting gpt attributes will prevent Drive Letter assignment on this partition.
Here's how you remove it from OEM partition. Let's assume in this scenario that the OEM partition has letter F and it's listed as Volume 4. Here are the steps:
1. Do a search for cmd and right click it and run As Administrator.
2. Type the following commands one by one (hit Enter after each one of them):
> diskpart
> list volume
> select volume 4
> remove letter=F
Done.
Hello,
I'm a new member, just joined to comment on this post.
I also just updated to Windows 10 build 1803 and was presented with a new drive D.
I do not see this as a minor issue. When I insert an SD card into my laptop, it is assigned the drive letter D, and I have procedures setup to recognize drive D. Microsoft displaying a hidden partition and assigning it a drive letter, in my opinion, is not a minor issue. I hope Microsoft fixes this problem promptly
Agreed that this is an annoyance but the diskpart commands mentioned above worked for me. Surprisingly, I tried to fix it first using mini-tool and it wouldn't work. On a positive note, it is nice that Microsoft finally hides Recovery and other non-optimizable partitions/volumes under "Optimize."
