Using The Application Recovery CD(s)
The Application Recovery CD utility enables you to reinstall individual software, individual drivers, and to repair software if
they become corrupted or are erased. You can reinstall a software application or driver to correct a problem that you are
experiencing with your computer, peripheral hardware, or specific software. You may not need to reinstall the entire
contents of your hard drive. You must be in Windows to run the Application Recovery CD utility.
To reinstall all of the software that shipped with your computer, use the System Recovery CD(s).
