Hi Michael,
Full transcript below (including a couple of dec to hex translations of
seemingly pertinent values).
As you can see, I'm in the context of explorer.exe (pid 2528) - the process
owning the window objects.
$ python vol.py --profile VistaSP1x86 -f VistaSP1x86*.vmem volshell
Volatility Foundation Volatility Framework 2.5
Current context: System @ 0x831528a0, pid=4, ppid=0 DTB=0x122000
Welcome to volshell! Current memory image is:

To get help, type 'hh()'

Appreciate your help!
