Thanks for your response:
Windows 7 was pre-installed on the new Dell. I was given a disk with it & assume that was used.
Maybe I'm just not knowledgeable enough about what some of these terms mean.
Internet Explorer is 11 (11.09600.18376 11.0.33 KB3170106)
The old Dell with Vista is retired. I was told it was on it's last legs.
(I have changed the settings to "never allow updates" since someone suggested that.)
I've gotten 24 messages from the community and trying not to just try everything that I'm hearing to do for this.
Thank you for sticking with me.
