(caution - Product Keys listed)
What are you talking about when you say this
You can use any of those utilities on your own machines for your own private local use without concern.
However, if you are planning to use one of the utilities to assist a victim in a forum reply setting, you should know yourself, and alert the the victim that, any report that they may be asked to post "could" contain proprietary, secret, personal, specific Product ID Key or Product Activation Code information specific to various commercial products they may have installed.
For instance, some of those utilities will Report out the Product ID Key for Windows Operating System or for Microsoft Office application installation. (25 item alphanumeric code required for use when installing Windows, or when installing Office or other products)
Those Product Keys "could" be used by an unscrupulous reader to install the same commercial product onto their own machine using your victims Key information.
If an unscrupulous user does get any of that information and uses it, problems could develop for your victim later when they attempt to run Windows Updates, etc., because the WGA could fail.
_____________
What should you do when asking a victim to report out information using one of these utilities?
–Be familiar, yourself, with where the utility lists such information.
–Know how to assist the victim with editing the report before posting.
–In most cases, even after the report is edited, have the victim attach the Report as an Attached File in their post.
(this last is because "bots" do not (presently) scan attached files, but they do regularly scan information typed or copy/pasted directly into forum posts.)
It's a wonderful world.
