Please followup-To alt.comp.os.windows-10. (Note this is not just a
Windows question, but I believe the Windows newsgroup is more
appropriate: perhaps there are other system's shrinking tool that could
help me here. Thanks for any ideas.)

I'm interested in installing a new operating system. Haven't decided
which yet---perhaps FreeBSD, perhaps GNU Guix. I've got 195 GiB free in
my c: drive plus 655 MiB unallocated which I was able to get from
shrinking the c: drive using the Windows 10 Disk Management tool.

Disk Management (how my storage looks right now)

Disk Management is not able to shrink more. It says it has been done
what it could with those 655 MiB.

I turned hibernation off, restarted and tried again. Same thing.
Looking at the defrag event in the application log, I find:

--8<-------------------------------------------------------->8---
A volume shrink analysis was initiated on volume (C:). This event log
entry details information about the last unmovable file that could limit
the maximum number of reclaimable bytes.

Diagnostic details:
- The last unmovable file appears to be: \System Volume
Information\{fba11b84-afde-11ef-adfe-48684ad40403}{3808876b-c176-4e48-b7ae-04046e6cc752}::$DATA
- The last cluster of the file is: 0x76e787e
- Shrink potential target (LCN address): 0x466119b
- The NTFS file flags are: ---AD
- Shrink phase: <analysis>

To find more details about this file please use the "fsutil volume
querycluster \\?\Volume{f5e639db-a758-4dfa-9804-d5d4d0286fb7}
0x76e787e" command.
--8<-------------------------------------------------------->8---

Using the fsutil command, I get:

--8<-------------------------------------------------------->8---
C:\Windows\system32>fsutil volume querycluster \\?\Volume{f5e639db-a758-4dfa-9804-d5d4d0286fb7} 0x76e787e
Cluster 0x00000000076e787e used by ---AD \System Volume
Information\{fba11b84-afde-11ef-adfe-48684ad40403}{3808876b-c176-4e48-b7ae-04046e6cc752}::$DATA
--8<-------------------------------------------------------->8---

Anything else I could try? I have not tried to use other system's
shrinking programs. Could they do a better job? Perhaps this is not
the best newsgroup to ask this question.
