    According to everything seen:

    The first 400MB recovery partition is obsolete, not in use. You can delete it.

    The EFI partition is the partition the computer boots from. You can move that to the very front of the disk after you delete the 400MB recovery partition. If there is a "MSR" partition that MiniTool shows you which is not on disk management, you can delete it. It is "reserved for future use" and no one has had any problems after deleting it.

    You know what the next two partitions are.

    The 493MB partition is the active recovery partition. If you delete it then you won't have the advanced troubleshooting menu that you get if you have problems - such as reset this computer, enter bios, boot from another device. I would leave that one there.

    The last partition contains the image that will be used if you select the option to reset this PC. Performing reset this PC with that partition there will more than likely take you back to the factory installed software. It is up to you if you want to delete it or not. Delete it and the only way to reset your PC back to some kind of initial state will be to clean install Windows 10 from an install USB/DVD or restore the computer from a factory restore USB/DVD.

    If you decide to delete that partition, then you can move the 493mb recovery partition to the end of the drive. As long as you don't desperately need that 24.55 GB of space, I would leave that partition there as it is being recognized by Windows 10 as containing a factory restore image.

    If it were my computer, I would only delete the first partition, move the EFI partition to the front of the disk, delete any "MSR" partition if MiniTool showed one, leave the last two partitions there, and adjust the C: and E: drive partitions to the sizes I wanted. I would also remove the drive letter "D:" from the recovery partition and assign "D:" to the data partition after the C: drive partition.
    A couple of things, I don't understand the meaning of moving the partitions to the front and the end of the disk, sorry. Second, the MiniTool shows one more partition (Not MSR). Here's the screenshot :

    Will simply resetting the Windows solve the problem? Since I can do reset as I haven't done much work from the time I upgraded.

    The 128MB reserved partition is the "MSR" partition I mentioned. If your only problem that you are trying to correct is that you can't shrink C: drive any more - just using MiniTool Partition Wizard to shrink it will do it. You don't have to change anything other than the program you are using to adjust your partition size.

    Windows built-in disk management will only shrink the OS partition down to the size when it hits the first system file in use by Windows. It won't let you shrink past that last file, whatever it happens to be. MiniTool Partition Wizard will overcome that limitation by rebooting the computer and running before Windows loads so that it can move system files out of the way to shrink the OS partition.

    Okay, thanks a ton for helping me out! I'll delete the MSR partition and the OBS partition and shrink the C Drive. Thanks a ton again!
