How do I watch the Registry for changes?

I know there is a FileSystemWatcher component that will watch a directory and fire events when changes are made to it, but is there a similar component that will monitor the Registry?

I have not tried this, nor have I really looked into it, but maybe this is worth a review:

Of course you have the normal API's which monitor the registry for changes, but if you just want an application then I reccommend this one:

The file is called 'regmon' & is a superb program which is FREEWARE
