My question is probably poorly formulated.
In fact -- as I discovered -- some WMI objects reflect their values in
the Windows Registry keys (for example there is mapping
“root\cimv2:Win32_OSRecoveryConfiguration.AutoReboot” in
“HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl\AutoReboot”).
Is there some *common* attribute of WMI/COM/OLE objects giving the key
path?
I don't believe so. The thing about WMI is that it provides a
uniform and accessible layer on top of quite a lot of lower-level
APIs. In some cases, that's a layer over registry entries; in other
cases it's a layer over an actual API call. It may even be the only
publicly-accessible means of achieving some result.
As it happens, for *methods* there is sometimes a clue as to the
underlying API. I have exposed this as (for want of a better name) the
provenance attribute of a method class. So if you do this:
<code>
import wmi
print wmi.WMI().Win32_Process.Create.provenance
</code>
You'll see something like this:
Win32API|Process and Thread Functions|CreateProcess
I'm not aware of any such thing for attributes, although it wouldn't
surprise me utterly if there were.
I know that the dependence WMI <-> WinReg is not frequent. Saying
“common attribute” I thought common to this (reflecting) type of
objects. So it seems that it was an exception that I managed to print
this thing.
Or is it possible that the attribute belongs to underlaying COM or OLE
object? (In the pywin32 implementation!)
I wonder which object it was... :-/ What a pity that interactive shell
does not remember the history of commands after rebooting the
computer… :-D

Hello,
I was advised to look at the ``MappingStrings`` qualifier. So far it
seems that the only way is to list ``MappingStrings`` qualifiers of
all properties.
[... snip code ...]
Thanks for the hint. I'll take a look at that myself with a view
to fitting it into the wmi module
