the windows registry may contain keys whose names with embedded nulls
when i call _winreg.OpenKey(key, subkey_string_with_embbeded_null) i get the following error:
TypeError: OpenKey() argument 2 must be string without null bytes or None, not str
Q1: is the meaning of the error that python _winreg module has a limitation that it cannot open keys whose names have embbeded nulls?
Q2: how do i get around this limitation?
Q1: right.
Q2: download and install win32all.
