To me it looks like your supposed to uncheck the boxes so they are disabled, what ever feature you choose not to use, but I don't think your not supposed to delete them completly. Is this what you have done, uninstalled the devices?
I did reinstall all of them but then I cannot update my computer. I open Control Panel and then I open automatic updates, it reports [bold]An exception occurred while trying to run "C:\Windows\System32\shell31.dll, Control_rundll "C:\windows\system32\wuaucpl.clp",Automatic Updates"[/bold]. I use Winxp pro sp2.
I couldn't tell you. Go to microsoft updates and see if it can do or turn on automatic update for you.
