Good evening.
As it has been a couple of days... if you have a copy of autoruns.chm, and you get one if you download a fresh copy of Autoruns from
here, right click it and select
Properties and then click
Unblock and OK your way out - this is the Help file.
If you click
Disabling and Deleting Entries on the left you can read the answer to your question first-hand -

If you don't want an entry to active the next time you boot or login you can either disable or delete it. To disable an entry uncheck it. Autoruns will store the startup information in a backup location so that it can reactivate the entry when you recheck it. For items stored in startup folders Autoruns creates a subfolder named Autorunsdisabled. Check a disabled item to re-enable it.
You should delete items that you do not wish to ever execute. Do so by choosing Delete in the Entry menu. Only the currently selected item will be deleted.
