"Local disk (E:) is running out of space"

After installing the April update Windows keeps nagging me about the E: drive running out of space. I only have one drive installed so I'm guessing it's some sort of system reserved partition but it didn't appear before installing the update. Is there any way to hide the drive or stop Windows notifying me about it every 30 seconds?
