Finding the changed subkey under a particular registrykey

[rakesh_nits]

Hi All, I want to watch a particular registry key and whenever any sub key under this key changes i am trying to get the name of that subkey.for getting when a particular key is changed I can use RegNotifyChangeKeyValue but this only tells me that the key has been changed it didn't tell which subkey has been changed under the key which i am watching.One way will be i can compare the registry tree befor and after the changes which will be a very clumsy and tedious solution.Any suggestions how to do this?Any help will be greatly appreciated.Thanks in Advance.
