Program to view what another Program is doing when it is run?

Ok just a quick update, I downloaded and ran process monitor, was missing a dll at first but fixed that problem then the first time I ran it windows instantly shutdown then rebooted, then I tried opening process monitor again and it does open but I get a error saying "Unable to load Process Monitor driver" so all capturing is disabled, have googled this and tried what people suggest but can't get it to work, any ideas? Thanks.

Kind regards,

Kevin
