Registry Key extraction and migration

[ed]

Hi I want to write a tool to do the following:
1. extract and display registry keys under abritrary starting point,
for example:
source are: HKey_Local_machine\software\old_lcoation or
HKey_current_user\software\XXX\YYY

a) then, I can specify where the Keys can be copied and compare the
new location to the new location. For example: destination are:
HKEY_local_mahcine\software\New_location.

b) if the keys are not there flags error message

how canI do that?

Ed,

Take a look at _winreg module. It supports
everything you are looking for. You were not
perfectly clear on what keys/values you needed
so the code below is a guess...

import _winreg
regkey='software\old_lcoation' # Copied your spelling
value_name="XXX"
key=_winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, regkey)
value=_winreg.QueryValueEx(key, value_name)[0]

new_value="YYY"
key=_winreg.OpenKey(_winreg.HKEY_LOCAL_MACHINE, regkey, 0,
_winreg.KEY_SET_VALUE)
_winreg.SetValueEx(key, value_name, 0, _winreg.REG_SZ, new_value)
