Registry Clarification

Hi,
I need to obtain the number of subkeys in a given
key and then I need values for particular entries in
each subkey read. Tell me if the procedure I’m using
is correct.

  1. Open Key using ZwOpenKey

  2. Use ZwQueryKey, with KeyFullInformation and extract
    number of subkeys. (what exactly does “class name
    refer to here”

  3. For loop from 0 to count and in each loop,
    a. Use ZwEnumerateKey to get subkey name
    b. Open the subkey with Zwopenkey
    c. Finally use n number of ZwQueryValueKey to obtain
    the values required

I thought of using ZwEnumerateValueKey, but how do you
pass the entry name (ValueName) that you want to read?
I could have used RtlQueryRegistryValues, but that
seemed more complex.

You don’t have to use the ZwQueryKey before calling ZwEnumerateKey. Just
call ZwEnumerateKey until you receive the error NO_MORE_ENTRIES (or
something like that)
