Windows 10 v1803 April 2018 The update brought many new and improved features. However, many users have reported that it creates additional OEM or recovery partitions . It is essentially a WinRE partition. They cannot be deleted immediately because they are assigned a logical drive letter.
This excess partition is visible in both File Explorer and Disk Management and occupies (at least virtually) disk space. In some cases, the system starts with the message that the disk is full. Also, when you check the disk usage in Task Manager, you can see that it is approaching 100%, which slows down the system.
Windows 10 v1803 creates an additional disk partition
To solve the problem, try the following suggestions :
1] Hide logical drive
The drive is needed to recover Windows 10, but it practically takes up space. We could hide the partition so that it does not appear in the File Explorer.
However, if you really want to delete the additional partition, this is not possible via Disk Management. They don’t display the option for the same thing. You may need to follow these suggestions.
2] Delete with third-party software
Although disk management may not work, third-party partition management software may help you delete the partition.
3] Use the disk portion
You can use a high prompt instead of disk management to resize/delete the additional partition. Run the following commands:
diskpart List volume Select the volume . Remove letter=X : Output
Here X : is the drive letter.
This step removes the excess partition and corrects the problem.
4] Delete MountPoint
Right-click Start and select Command Prompt (Administrator).
Type the command mountvol X : /D and press Enter, where X : is the drive letter.
I hope it works for you.
