Windows 10 OEM Partitions

I have 2 OEM partitions on my windows 10, Disk 0. Both are small; one 350MB and the other 450MB (drive G). The later is within 10% of being full and I am constantly getting a system message making me aware of this space issue. Please can anyone tell me what these partitions are used for and if I need them? If they are required how do I increase or move drive G? thank you.

    Microsoft is aware that previously-hidden partitions are improperly being assigned drive letters after installing the April 2018 Update. As a result, they now appear in Disk Management and File Explorer. These partitions are typically recovery partitions used by the Windows Recovery Environment or by the Original Equipment Manufacturer. It is not recommended that you attempt to delete or reformat these partitions as this may have adverse effects on your ability to recover Windows. Microsoft is currently working to address the issue in a future Windows Update, and we’ll update this thread when a solution becomes available.

    (Update 5/14/18: The solution that will soon be released via Windows Update will only prevent this issue from occurring for devices that install the April 2018 Update after the solution is released. If you've already installed the April 2018 Update and are experiencing this issue, you'll need to follow the steps below if you want to hide these partitions.)

    Although you can safely ignore these partitions, if you prefer do away with the low disk space warnings and hide the partitions so they no longer appear in File Explorer, you can do so by manually removing the partition’s assigned drive letter. To do this:

    1. Select the Start button, type cmd and then right-click Command Prompt in the search results and select Run as administrator.
    2. In the Administrator: Command Prompt window, type diskpart and press Enter.
    3. Type list volume and press Enter.
    4. Make note of the volume number for the drive letter you want to remove. For example, if the drive letter you want to remove is Drive “G”, note the volume number for Drive G.
    5. Type the following command, and press Enter.

    select volume <volume number>

    When typing this command, in place of <volume number>, substitute the volume number you made note of in Step 4. In the example above, if the volume number for drive G is 5, you would type: select volume 5

    1. Type the following command and press Enter.

    remove letter=<drive letter>

    When typing this command, in place of <drive letter>, substitute the drive letter you want to remove. In this example, you would type: remove letter=G

    1. Close the Command Prompt window.

    Hi Simon, this is a known issue in the 1803 Update,

    It is the recovery drive, you are not meant to see it, it is not meant to have a drive letter, remove the drive letter and everything will return to normal:

    Click your Start Button, type cmd, then right click Command Prompt and choose 'Run as Administrator'

    Run this command and hit Enter

    diskpart

    In the second Command window, run this command and hit Enter

    select volume G

    In the second Command window, run this command and hit Enter

    remove letter=G

    Close Command Prompt

    That's It!

    You need both of the Recovery partitions.

    This is one of the known issues with the update as Recovery partition should be hidden and is accidentally assigned a drive letter.

    Right-click Start>Command Prompt(admin)or Powershell(admin)

    Type in the following commands one by one:

    diskpart

    list volume

    select volume 3

    Replace 3 with the number of the volume which is assigned a drive letter. (In hundreds of MBs)

    remove letter="G"

    Also, see:

    Don't worry, removing a drive letter would not cause any harm to your device.
