Fix Autoruns Disabled Folder Launches Automatically at Startup

The AutorunsDisabled folder, as the name implies, contains the startup folder items that are disabled using Autoruns, the startup manager from Windows SysInternals. This folder is located under the Startup folder (separate folders for per-user startup and per-machine startup locations) contains hidden attribute set by default so that these folders are not treated as startup items themselves by Windows. If the hidden attribute for the AutorunsDisabled folder gets removed somehow, then it’s considered as a startup entry and Windows shows the folder window at every logon.

To prevent this folder from appearing, simply reset the "Hidden" attribute to the folder.
Click Start, All Programs, Startup.
Right-click AutorunsDisabled and choose Properties

Enable the Hidden attribute and click OK.

Alternately, to reset the hidden attribute for this folder, open Autoruns and disable a startup entry (the one which starts from the Startup folder, and not from "Run" registry location) and enable it back again.
