How to compare RSoP before and after making changes to your Group Policy infrastructure.

Have you ever wanted to compare Resultant Set of Policy (RSoP) information before and after making some change to your Group Policy infrastructure? There’s no simple way of doing this using the Group Policy Management Console (GPMC), but there is a workaround. First, before you make your changes, run the Group Policy Results wizard from within GPMC and save the resulting RSoP info as an HTML report. Then make your changes i.e. add/remove GPOs, change GPO settings, and so on. Now run the GP Results wizard again and save it as another HTML report. Then use the windiff utility (see http://support.microsoft.com/default.aspx/kb/159214) to compare the two files.
