Hmm, the first parameter to SaveKey needs to be an HKEY object. You can get
one of these by calling _winreg.OpenKey. So for example:

import _winreg
key = _winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, "Software\\Adobe")
_winreg.SaveKey(key, "c:\\python23\\samplekey.reg")

However, when I do that, I get a WindowsError: A required privilege is not
held by the client. The documentation says that SeBackupPrivilege is needed
to call SaveKey. It happens when I run it as administrator as well though,
so I'm not sure what's happening there.
