I am not sure if most people still use Windows Explorer, but I gave up on it some time ago. I found an app called ExplorerXP at http://www.explorerxp.com/ that is fast and free. I had found that regardless of my preference settings with Windows, some folders were still hidden by Windows Explorer. Not so with ExplorerXP. As the name implies, this app is only designed for Win XP/2000.
Just thought I would share one of the apps I find very usefull.
