In the Windows 8 "Performance Information and Tools" Control Panel, there's an advanced section that shows detected performance issues.
If you click on one, it opens a small dialog summarizing the problem. One of the buttons on this dialog is "Remove from list", which I now know persistently hides information on that performance issue in the future.
However, the purpose/behavior of this button is NOT CLEAR. I was looking at the notification about programs slowing Windows startup, and the recommendation is to remove programs from the auto-start list. In that context, I understood that the button would take me to my list of startup tasks so I could remove or disable some. Of course it didn't.
How can I undo "Remove from list" / reset the hidden issues so that they appear again?
