The problem with the tool is it will show only the area where Win settings have been alerted; not what the specific change was.
Here's an example. On my Win 10 build, I modified system restore settings to do so only for the drive it is installed on; not for all the drives I have installed. When I run the tool, it only informs me that a change has occured to System Restore settings. If I run the tool, system restore will be reset to run all my drives.
Bottom line - if you are one that makes custom mods. to Win settings, this tool will remove all your custom settings.
