Notice that the number is actually negative: -2147481643
which equates to hex 800007d5. Might be worth searching on
that. Meanwhile...

... I can't easily think of a situation under Windows when
explorer.exe *isn't* running, since it powers thing like
your desktop. This code snippet, for example, shows
the explorer processes running on my machine with
nothing running in the foreground except the Python
process itself:

<code>
import wmi
for i in wmi.WMI ().Win32_Process (Name="explorer.exe"):
   print i.CommandLine

# => c:/windows/explorer/exe
</code>

What are you trying to do with the explorer.exe
once you find it?
