I'm trying to install a Windows 10 update, but I'm getting an error that as far as I can tell is because my system partition is full. So I'm going into a partition manager, and as far as I can tell I need unallocated space near the system partition in order to expand it. I want to take space from my C: drive, but the problem is that I can only seem to create unallocated space right next to the C: drive and between the C: Drive and the EFI System Partition, there is a 128 MB Reserved Partition that I can't figure out how to move, or extend, or merge, do anything to at all.
So how do I extend the System Partition when I can't seem to do anything to the Reserved Partition and it is in the way?
This is a screenshot of what I'm looking at on my partition manager:
