Since a few weeks back and probably some Windows Update I have a new partition on my System that is 450mb large. If I look at it it's empty. I wouldn't really mind, but every five minutes I get this popup that there's low storage on the HD.
So I tried to expand this volume, but on this one I don't have the options to expand/decrease the volume. Actually, theres only the Help option when rightclicking.
All other partitins have the options
It probably contains critical boot files that are hidden to prevent tampering. You need to remove the drive letter instead. That will make it disappear from File Explorer.
