Re: My opinion on this?
Ralph, you post doesn't do the link justice.
You should clarify that the link is to a remarkably helpful tool that will stop the nagware, prevent inadvertent deployment of Windows 10 by desktop users, recover lost disk space and hopefully prevent mobile users busting their data limits downloading a large Windows 10 installer.
It has a helpful command line interface for use in enterprise environments which is vital for smooth and effective deployment.
It will also clear up gigabytes of disk space lost when GWX installs, some people have claimed it's freed up over 10GB!
PS. I have no connection with the author.
PPS. User beware - take the usual precautions before deploying any application...test it!
