It's a program installed by PeoplePC, and it's not needed. Use MSCONFIG to
disable the item and see if the error disappears and also see if you have
any remaining problems (test several sites with IE, use OE to Send/Receive
mail, etc.) If no problems result from disabling Bartshel, return for
instructions on permanently preventing it from starting up with Windows.
Unless you're going to switch from ad and spyware-laden PeoplePC to
something more sane, do not uninstall any of its components.

Start>Run>MSCONFIG<enter>

Look on the Startup tab for the Bartshel item, uncheck it, click OK and
restart when prompted.
