    Disk Management Query


    Hi,
    Below is a screenshot of my Disk Management Console.
    With the C drive and it's partitions highlighted in yellow.

    I was wondering,
    if this looks correct/typical for a win 10 C drive?
    Also,
    would removing the 475MB Recovery Partition,
    make much of a difference?
    I'm trying to find out,
    if I'll gain anything,
    by removing the aforementioned partition.
    Should I just leave well enough alone,
    and refrain from changing/disturbing anything,
    so as to avoid unintentionally causing problems?

    Really no need to mess with it to be honest. That 475MB is not enough to even bother with it I would say. It is less than 1/2 of a GB. If everything is working fine, just leave it. And to answer your question, my C:\ looks exactly the same with the exception of the extra Recovery partition.

    @Geosammy
    The Disk Management indicated that you upgraded to Windows 10 from Windows 8. So your Disk Layout is a little bit different from normal Windows 10 Installation. The extra 475MB Recovery partition was created during upgrade to store WinRe.wim (Windows Recovery Environment). If you remove this partition, you won't be able to boot into Recovery.

    In addition, there's a 128MB MSR partition (hidden from Disk Management) between the EFI System partition and C drive.

    To see all partitions including the hidden one. Open Admin Command then type:

    diskpart
    select disk 2
    list par
    exit

    Whad'ya Know?... you're correct.
    I was wondering why I noticed 5 partitions and only seen 4.

    I'm guessing the best thing I could do for now,
    would be to leave it as is?

    Will I really gain anything form removing useless ( or what I think are useless) partitions?

    You can use MiniTool Partition Wizard (MPW) to peruse those recovery partitions. You will probably find that the 475MB is newer and should be kept. You can use MPW to delete the recovery partition at the start of the drive, move the 100Mb EFI system partition to the start then extend C: to use up the free space. You should make a system backup image using something like Reflect before fiddling with these partitions since you PC could fail to boot if errors are made.

    @Steve C
    I'm not quite sure what "preuse" is referring to.
    However, thanks for your suggestion Steve C.
    I'll definitely be checking out MPW.
    You wouldn't happen to know,
    if this tool is available at MojorGeeks?
    Never mind... it is available at MojorGeeks after all.

    Do you think there's any way of telling,
    which recovery partition is older or most recently created?
    Is there some kind of timestamp value somewhere?
    I'd be interested in knowing this,
    if it can be done.

    I would suggest that the recovery partition at the end of the drive is the latest as that is the way the latest upgrades install has worked, but I would not chance any removal for the sake of a small space recovery.

    You could always wait for the SCU Ver 1803 17331.1 to be available and use an ISO to clean install to a completely empty disk - This will give you a cleaner faster system that has the partitions exactly as Windows now wants them. Back up everything first then wipe the drive and install from a booted USB installer (or dvd if you prefer)

    It will also mean that you have to re-install and setup all your existing applications and any changes to settings

    Thanks for providing the link Barman58 .
    Even so, I just downloaded it from MajorGeeks.
    I'll trash their file and as you say,
    use the file for the "source" instead.

    Now that's an interesting plan.
    I just might do that, when the time come.
    Thanks again Barman58, that's an excellent suggestion .
