I do not see demo's because i do not have it selected under show selected types via the store search. https://store.steampowered.com/search?supportedlang=english&ndl=1

Check if you have it enabled.

Some games have demos, and the discovery queue shows you games. Are you asking for a way to hide the "download demo" button?

All I'm asking is a way to make listed free DEMOs not show up anywhere in my Steam program. Like an on/off switch for DEMOs Steam wide. I buy games, I don't want to wade through 100s of free Demos DEVs are trying to get me to download to pre test hi/her game before it's release. Thanks for your reply!

NX... Found your point, I did not have Demos checked and I did not have anything else checked in that section. I checked games and left everything else UN checked. I'll give that a try and Thanks!
