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

As it says in the _winreg.QueryValueEx documentation, you need to pass an already open key. EnumKey returns a string, not an open key.

aReg = ConnectRegistry(None,HKEY_LOCAL_MACHINE)
aKey = OpenKey(aReg, r"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall")
for i in range(1024):
    try:
        keyname = EnumKey(aKey, i)
        asubkey = OpenKey(aKey, keyname)
        val = QueryValueEx(asubkey, "DisplayName")
        print val
    except WindowsError:
        break
