    Drive H: reserved for system nearly full


    On my system, I got a drive ("H:") that is reserved for the system. My system is install on the "C:" drive
    What is it use for? I think I installed it few years ago, but can't remember why
    Could it cause my PC to reload?
    Any info appreciated

    If it's the system partition, it typically contains your boot information for starting the computer. It doesn't typically get assigned a drive letter. You can press [Windows key + x] select "Disk Management". If you see the H drive with the label "system partition" then that is all it is. Assuming the partition is on your main disk (Disk 0) you can remove the drive letter as follows
    • Open an elevated command prompt
    • Type diskpart
    • Type list disk
    • Identify which disk the system partition is on (you can do this from disk management)
    • Select the disk withselect disk #
    • Now list the partitions with list vol
    • Look for the one with System under the info column
    • Select it with select vol #
    • Now remove the drive letter with ​remove letter=H

    Nothing to worry about. That partition won't fill up any more than it is now.
    You should remove the drive letter assigned to it in disk management. It should not have a drive letter assigned to it as it is a hidden system partition containing the system's boot files.
