Can I disable the "Disable apps to help improve performance" notification?

It was driving me crazy, too. I found the answer in a comment from Troy Dallas on thurrott.com:

Once you get the Disable apps to help improve performance notification:

Go to Control Panel -> Security and Maintenance (right click on the Start Button and Left click on Control Panel to jump straight there).

Once opened under Maintenance (middle of the window) you will see the notification box with a Blue link at the bottom of the notification. Click that link Turn off messages about startup apps.

Important Note: The notification has to be in the Notifications Window before it will appear in the Security and Maintenance section.
