what do these settings do

Just curious if anyone else is getting this.

I go to click on a task, bring it up and click on (What do these Settings do?)

I get this pop up
Internet Explorer cannot download… Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try later. :THNK

I have been getting that all day.

Shut down computer last night.
Rebooted today

All working fine again (:CLP)
