Why does my laptop have three partitions while there is only one hard drive in it?

Since I upgraded from Windows 7 to 10 on this same laptop, when I go in the windows defragmentation utility, there are three partitions thats shows up:

  • The main (C:) partition
  • The "System" partition
  • Another drive named weirdly " \?\Volume{9a3a97..." with a bunch of numbers and letters

I don't understand why the two other paritions other than the C: drive are there.

    probably because your title is bad and also your question lags a precise asked question. ... maybe someone considered your question too "dumb" ... but to answer your question why you have 3 drives: it is called "partitioning" see Wikipedia: en.wikipedia.org/wiki/Disk_partitioning ... in regard of your optimization question: windows 7 and later will optimize the disks if needed in the background while you do not use the pc – masgo Sep 14 '16 at 13:55

    Could it be possible that I never had these 2 others partition before the windows 10 upgrade? – Martin B. Sep 14 '16 at 13:56

    @masgo - I wouldn't say its "dumb" nor should anyone. Confusing and not clear perhaps is the better term. – Ramhound Sep 14 '16 at 15:16

    @MartinB. - That is really only something you can tell us. – Ramhound Sep 14 '16 at 15:16

The main question has been already answered by @masgo: there are the three partitions and NOT the physical three new drives.

Could it be possible that I never had these 2 others partition before the windows 10 upgrade?

Yes, it is possible:

When installing a Windows operating system (OS) on a hard drive, and if you use Windows Setup to create new partition on an MBR disk, Windows will create a system reserved partition, and if it is a GPT disk, then Windows will create a recovery partition and a EFI system partition without drive letter. The recovery partition on Windows 10 consumes about 450MB, Windows 8/8.1 200MB, and Windows 7 100MB.

You can take a look at this article.


This is an simple thing. This has occurred because of partitions while you upgraded from Windows 7 to Windows 10.enter image description here
