_winreg in Python

[7raTEYdCql]

I'm trying to fetch values from a windows registry, using _winreg module in python.

This is function, which fetches a registry value:



def get_registry_value(sub_key, value_name):
registry = _winreg.ConnectRegistry(None, _winreg.HKEY_LOCAL_MACHINE)
key = _winreg.OpenKey(registry, sub_key)

value = _winreg.QueryValueEx(key, value_name)

_winreg.CloseKey(key)
_winreg.CloseKey(registry)

return value


Now when I pass, subkey = SOFTWARE\Microsoft\Internet Explorer\UnattendBackup\TrustedSites and value = 'TrustedSites' to the given function it returns a null string.

I checked for other key_value pairs it was returning proper values.

Any exceptions to what the length of the value can be? Cause, this is a string containing all TrustedSites on IE. Every other case on which I've tested this function, it has been relatively short string.

Any other forum on which I can ask this doubt, where it would be more appropriate?

This was executed on Windows Storage Server 2008 R2

Is there a chance that that value is actually a list of values - and not one big string ?

Do you need to used EnumKey or EnumValue on your open key to get all the sub values ?

Try calling QueryInfoKey in your open key and see if there are any subkeys

Thank you so much Tony, that was indeed of good help.
