Q: Can't delete OEM Partition in Windows 10.

"I have a Dell laptop for two years, and now the hard drive is running in low disk space. So I need to find a way to free up some space to get better performance. When checking the device, I notice that there is an empty partition, named Healthy (OEM Partition), occupying 14.75 GB. I don't know what it is exactly. When I open Disk Management and right-click on the partition, I only see the Help option without the Delete choice. How can I remove the OEM partition? And is it safe to do that?"

What Is Healthy (OEM Partition) in Windows 10

OEM partition is designed for system recovery or factory restore. It allows users to easily and quickly restore the system to the original state when system failure or system crash occurs. This partition usually comes with Dell, Lenovo, or HP computer. Some people want to delete OEM partitions to extend more space since they don't plan to restore the device to factory setting. Besides, you can also get to the same recovery features by simply booting off a Windows 10 CD or memory stick if you ever do have a problem booting up.
