Python code to read registry

Question

from _winreg import *

\"\"\"print r\"*** Reading from SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run ***\" \"\"\"
aReg = ConnectRegistry(None,HKEY_LOCAL_MACHINE)         


        

Answer 1

Documentation says that EnumKey returns string with key's name. You have to explicitly open it with _winreg.OpenKey function. I've fixed your code snippet:

from _winreg import *

aKey = r"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall"
aReg = ConnectRegistry(None,HKEY_LOCAL_MACHINE)

print r"*** Reading from %s ***" % aKey

aKey = OpenKey(aReg, aKey)
for i in range(1024):
    try:
        asubkey_name=EnumKey(aKey,i)
        asubkey=OpenKey(aKey,asubkey_name)
        val=QueryValueEx(asubkey, "DisplayName")
        print val
    except EnvironmentError:
        break

Please note, that not every key has "DisplayName" value available.
