Like if I clumsily set the fan speed maximum two 2 billion RPM and I want
to get it back to the starting levels without doing it manually with the
scroll wheel. I can reset the time bar by choosing a time option. But how
do you reset the minimum and maximum chart values?

Thanks.

Do they use the Registry for their settings,
or being Open Source, have they left a file
in %userprofile% for this purpose ?

You can watch the program using ProcMon (Process Monitor)
from Sysinternals.com if you want, and detect registry
transactions there.

When a person writes a program, sometimes they
attempt to store preferences in a file stored
in the Program Files folder. This is verboten.
On a modern OS, the file ends up actually stored
in a Roaming folder. The Program Files folder set
is owned by TrustedInstaller, so you would not
normally have permission to write in there. And
then storage of preference files would fail.
But since the OS has a "redirection trick" it uses
so programs of that sort won't break, it gives
the impression it worked.

In any case, whether I'm looking for WriteFile
transactions or Registry operations, those
could be tracked in Process Monitor. By setting
the filter in Process Monitor, you can ask it
to only show you transactions for the program
you're working on.

You could also use Regedit and search for the
key in there, but it doesn't take much to make
finding it almost impossible. For example, if the
Registry entry used "OHM" instead of
"Open Hardware Monitor", you'd have
fun finding it. That's why I'm recommending
ProcMon as an alternative, in case the program
is "hiding".
