Click Start, point to Settings, and then click Control Panel.
Double-click Add/Remove Programs.
On the Install/Uninstall tab, click Microsoft Internet Explorer 5 in the list of installed programs, and then click Add/Remove.
Click "Add a component to Internet Explorer," and then click OK.
In the Windows Update dialog box, click the installation type you want, and then click to select the check boxes for the components you want to install. You want to put a check in the Microsoft Outlook Express box to get an update...since your Outlook Express isn't bold (it shouldn't be bold anyway).
NOTE: Components in bold on your screen are ones that are already installed
Click Next, and then follow the instructions on your screen.
I hope this works
