Why need to merge partitions in Windows 10/8/7?

A hard drive needs to be partitioned into several parts for better management. However, sometimes it was not reasonable-partitioned. For example, C drive for operating system is not big enough and D drive somehow is too large and useless. In that case, merge C and D drive would be an acceptable solution for storage utilizing.

What’s more, you need to reduce primary partition amount if you run Windows on an MBR disk. MBR disk style has the limit of up to 4 primary partitions. When it overpasses 4, you cannot create new primary partitions any more. You could either convert MBR to GPT to break the limit or merge two primary partitions into one to minimize partition amount.
