Now that M$ owns Systernals, it is in their interest to prevent those files from accessing things they don't want you to see. As time progresses they will provide less and less functionality with such tools so others will not clearly know what is going on "under the hood." Systernals acquired their knowledge without the assistance of M$ and developed their tools to show what THEY wanted to discover.
If you think that a "new" file that is at least 3 times bigger that the previous file, without any apparent added functionality is "better" you are, always, free to use what MS makes available to you and avoid the downloading of the "original files."
The only thing I have seen on their site is discussion of some additional functionality for VISTA is some of the releases, but we can be relatively sure they are carefully tailoring what we can see and what we can't to suit their own needs.
You get to choose. No one is twisting your arm to download anything.
