Maybe the uninstaller on something did not clean up ?

I've seen the odd item using    dir /ah   when inspecting
the folder. I don't see a particular reason for *anyone* to be
making files hidden. Even though Process Monitor puts a hidden
"procmon23..." file in System32 (for boot logging) and does not
remove it later.

Maybe it had a service set up that puts a display in the toolbar
("TrayIconRenderer"). It's possible Speedfan had something like that
concept as well.

If fan controller softwares are being used, two should not be
run at the same time, as the SMBUS master is not thread safe.
Only one "reader" should use that bus at a time, at runtime.
The bus can be corrupted if two programs are running, but
this might only affect the readouts (and behaviors) of the
two programs, rather than crashing the system.

You can use nfi.exe to make a file list. But it does not
do a good job on hardlinked files (it only lists one of the
two filenames such a file goes by). nfi.exe is not thwarted
by permissions (it only reads the $MFT). But Everything.exe
when it lists files,  anything which is "Access denied" won't
get listed, as it reads the $MFT, but it also traverses
the folder tree.

nfi.exe is in this zip, and it would be really "handy" if Microsoft
would re-write this for modern times. I've run into one file
in the $MFT (I was writing a program similar to nfi myself),
that didn't have a $FILENAME, and stuff like this makes me
angry. CHKDSK would not remove it, implying the structure
was <cough> perfectly normal.

   (administrator command prompt)

   cd /d %userprofile%\Downloads
   nfi.exe c: > nfi-c-out.txt
   notepad nfi-c-out.txt

If you make a backup of C: with Macrium, then mount the C:
partition as K: and tick the "remove file restrictions" tick
box while mounting the .mrimg as K:, then, a program like
Everything.exe should be able to list all visible files.
There will always be a few items, that Macrium will not back
up, so there might not be a pagefile.sys in there for example.
Making a backup using the Macrium CD might get you a little
closer to a thorough backup.

Windows Defender has an "offline scan" it can do, which while
the item is not malware, maybe the suspicious driver list will
find the item.
