How to intercept a registry or memory key while for example I am changing the Google Chrome window size? Is there a soft/freeware I can use that would list changes I am making in the computers memory / registry?
More specifically I am collapsing and expanding a tree view in a Excel's VBE Project Explorer and I would like to know what data is getting changed so I can programmatically manipulate it afterwards
