A client of mine hosed part of their registry. For some reason, a bunch of sub keys under the HKEY_CLASSES_ROOT have no permissions set. So I am going through the keys and manually setting keys as such:
There are potentially thousands of these that need to be set and it's a 10-12 step process to do for each key. So I want to automate the process via Python. Is there a module that can accomplish both of these?
Thanks!
After almost a whole day research my solution to working with windows registry and permissions is to use SetACL. You could use a COM object, or use the binary file and the subprocess module. Here is a snippet from what I used in my code to modify the permissions in a mixed environment (I have ~50 Windows machines with 32bit and 64bit, with Windows 7 and Windows XP pro ...):
from subprocess import Popen, PIPE
def Is64Windows():
'''check if win64 bit'''
return 'PROGRAMFILES(X86)' in os.environ
def ModifyPermissions():
"""do the actual key permission change using SetACL"""
permissionCommand = r'SetACL.exe -on "HKLM\Software\MPICH\SMPD"'\
+' -ot reg -actn ace -ace "n:Users;p:full"'
permissionsOut = Popen(permissionCommand, stdout = PIPE, stderr = PIPE)
pout, perr = permissionsOut.communicate()
if pout:
print pout
sys.exit(0)
elif perr:
print perr
sys.exit(1)
def main():
... some code snipped ...
os.chdir('SetACL')
if Is64Windows():
os.chdir('x64')
ModifyPermissions()
else:
os.chdir('x86')
ModifyPermissions()
So, it's not really pure Python, but it works.
