Extending System Partition on Windows Server 2012 With Windows Disk Manager

Nowadays, more and more people use Windows Server 2012 and 2012 R2 to deal with their business. However, the system partition on Windows Server 2012 will run out of space someday. So I think the subject of extending system partition on Windows Server 2012 due to lack of volume or other reasons is still a good subject for computer users. Even a newbie knows that system partition will affect the whole computer’s speed. So we must clean the garbage files in time. Even so, we have to extend system partition to avoid the crashing of system and to improve the running speed in the end.

When it comes to expand system partition, someone worried about losing data naturally. I understand it. In Windows Server 2012, you can extend and shrink drives with its disk management. But, unfortunately, resize partition with shrink feature and then extend system C: drive with the extend feature is impossible usually. Because to extend a drive there should be an “unallocated” space behind it, so you cannot extend the system C: drive by shrinking the D: drive directly. The only choice is deleting volume D or moving it. This is not reality. Thus it can be seen that, to extend system partition on Windows Server 2012 is inconvenience with Windows built-in disk manager.
