Will it be possible to create a single Fixlet for monitoring the change in registry at higher level (HKLM/Software/)i.e for complete hierarchy in HKLM/Software/? Whenever there is change in HKLM/Software/* registry parameter then the corresponding fixlet will become relevant. If yes then let me know how to create a fixlet for the same.
There is not a way to do general purpose monitor for any/all changes in a registry key. What you can do is create Fixlets/properties to check for specific values that you do not want to change and alert for the change.
For instance, a simple example is that you want to make sure that the key “HKLM\Software\Test” exists. You would write Fixlet that says:
exists key “HKLM\Software\Test” of registry
Similar methods can be used to check any registry value exists and check the value of any key to make sure it is set properly.
