track change to registry before installing software [duplicate]

"There are a few common ways.

Take a copy (go in to the registry and export), then do the same after and compare the difference.
Use Microsoft/Sysinternals Process Monitor and track the changes.
Use VMWare Thinapp (Or Microsoft App-V/Softgrid, but harder to get) inside an application and actually track all the changes.
Use one of the many installer/uninstaller tracking applications.
Use a tracking program such as ""Tracker"", Personally, I love this application and use it all the time inside a virtual machine."
