WhatChanged
WhatChanged is a system utility that scans for modified files and registry entries. It is useful for checking program installations. There are two steps for using WhatChanged: 1) First, take a snapshot to get the current state of the computer; 2) Second, run it again to check the differences since the previous snapshot. WhatChanged uses the "brute force method" to check files and the registry. No longer available for download on authors website, but still can be downloaded from PortableApps.com at https://portableapps.com/apps/utilities/whatchanged-portable
