Preamble: My drive is divided into two partitions: the System one (C) and the Data one (D), plus the other classic windows System Reserved ones (not visible from the explorer). I use Windows 10.
Lately, my System partition (C) was completely full (down to under 1 Mo of free space at some point). So to survive, Windows 10 created a new partition (drive letter E) called System Partition, I imagine to store the bare minimum to function.
Now I cleared the mess and the classical System (C) partition has enough space to function correctly (over 15 Go). However the System Partition that it created (E) is still here.
How can I get rid of it without compromising my Windows install ? I considered merging the two (C and E) but I'm afraid this will has unintended side effects. Surprisingly enough I have not been able to find any report of this behaviour on the Internet.
