Usage of the tool is very simple, click on the 1st Shot and take a snapshot of your registry or save it to the location you specify. Now do any changes to the system or install the software and then click on the 2nd snapshot. Select your output LOG file type,”text” or “HTML,default is “text” and then click compare. The application will generate the report of the registry.
