WindowsError: [Error 5] Access is denied With _winreg.enum

[black_13]

I have included a small script the reproduces the error I am having in
larger script.
The line 'hkey = _winreg.OpenKey (_winreg.HKEY_L OCAL_MACHINE,na me)'
seems
to be causing the error but im not sure why.
--------------------- script ----------------

import _winreg
import string

def reproduce_error ():

for index in
xrange(_winreg. QueryInfoKey(_w inreg.HKEY_LOCA L_MACHINE)[0]):
#get names
name =
_winreg.EnumKey (_winreg.HKEY_L OCAL_MACHINE,in dex)
hkey = _winreg.OpenKey (_winreg.HKEY_L OCAL_MACHINE,na me)
print name

hkey = _winreg.OpenKey (_winreg.HKEY_L OCAL_MACHINE,'S OFTWARE')
print hkey
hkey = _winreg.OpenKey (_winreg.HKEY_L OCAL_MACHINE,'S AM')
print hkey

WindowsError: [Error 5] Access is denied

Your user does not have permission to open the registry key you
requested. On my local machine, HKEY_LOCAL_MACH INE/SECURITY is only
accessible by the SYSTEM account. Even Administrative users do not
have Read rights to that key by default.

If you want to skip keys you don't have permission to access, you
could do something like this:

import _winreg

for index in xrange(_winreg. QueryInfoKey(_w inreg.HKEY_LOCA L_MACHINE)[0]):
try:
name = _winreg.EnumKey (_winreg.HKEY_L OCAL_MACHINE,in dex)
hkey = _winreg.OpenKey (_winreg.HKEY_L OCAL_MACHINE,na me)
except WindowsError:
print "Could not access registry key", name
else:
print name, hkey

If you move the "print name" line up one line, you'll notice that it's
choking on the Security key. Go to Start --Run and type regedit. Go
to that key and right-click it and check its permissions.

On my PC the only user that has complete control is the SYSTEM. So
you'll probably just want to put an exception block in your function
that records the keys that you can't open and continues to run.
