I am grateful for the help supplied here, and was not reluctant to follow the check. I read the site and saw the instructions on how to check in linux/unix, but did not see the next bit which was the downloads of windows checkers. BTW when I did eventually download a windows checker it was by no means straight forward. I sussed it, but most of my colleagues wouldn't have.

There's a whole new vocabulary in this environment that will be impossible for a typical windows user to even comprehend.
