HP support said the install function from the repair/install files on separate partition on HDD would allow me to make additional partitions. Well, it did not. So, right after install completed, I went to disk management to do so. However, the installed win 10 is occupying 3% of 880g hdd, but disk mgt says that only 470M is unallocated and can be moved to another partition.

I did a defrag and it only slightly changed that number.

Why the discrepancy?

Product number:V9B64AA
HP All-in-One - 24-e025t
win 10

what is it you are trying to achieve, is it to shrink the C:\ drive?
because as it says, you can't due to an unmovable file stopping that process.
yes, you are only using 3% of that partition but there is obviously a file that lives at the end of the partition that is stopping it being shrunk.
chances are it would be a system file like restore points, recycle bin, pagefile or crash dumps.
you could try running cleanmgr, defrag and Disk Management from Safe Mode.

other partition resizing software may move files as it shrinks, so try EaseUS Partition Master for example.
