+## Callback Extension
+Callbacks.dll is a WinDbg extension that will enumerate all pointers inside of the following symbols for callbacks that are registered on the system:
+1. nt!PspCreateProcessNotifyRoutine
+2. nt!PspCreateThreadNotifyRoutine
+3. nt!PspLoadImageNotifyRoutine

+
+## How to use?
+The extension takes in either of the four parameters: _process_, _image_, _thread_, or _all_. 
+This just makes life a little bit easier when you're doing whatever it is you're doing with them.  
+
+This just lists the callbacks, nothing more nothing less but as I continue working on my shenanigans...I will make sure to continue adding on to this.
+
+Have fun!
