From Adobe Reader downwards they are probably all unticked already, that is fine.
Upwards you can safely untick them all, but I would leave Windows Defender & Avast Antivirus ticked so your computer is protected at start up.
Removing the tick means that particular program will not open in the background when you start the computer, when you do want to use that program all you need to do is find it and open it up. Removing the tick will not uninstall anything, it stops things from staring up that is all (although some things need to be open at start up you are fine)
