Ignoring other complications... you're querying the keys on the
remote machine "XXXX". But you're then using _winreg to query
the values on the local machine. Why not continue to use the
WMI registry methods:

to query the remote keys?

By the way, the pythonic thing to do is to iterate over lists
directly. You don't need to do the "while i < len (list)" dance.
Just:

for name in names:
   try:
     # do stuff with OpenKey ("..." + name)
   except <some Exception class>:
     # handle and move on

Also, don't put a bare "except:" unless you're absolutely sure
you'll need it. In the code below, that except: would silently
ignore even a NameError or a Ctrl-C.
