Try the System Configuration Utility known as msconfig. Go to Start > Run, type in msconfig and click OK. When the utility opens click the Start up tab.
Look for your folders there, and if you find them, de-select them. Click Apply then OK. If you get a message to restart the computer you can do it then or later as you wish.
When you do reboot, you will get an information window telling you that you have chosen selective startup. You can suppress that window from within the window itself.
