Have you looked into free conversion online? LWP to DOC/DOCX?

If you have a Windows 7 disc, you could get free hypervisor software (like VirtualBox), and then install Windows 7 on a virtual machine. If you've got your LWP files on a USB stick - you could access that from within the Windows 7 virtual machine. Doing all this would be more of a pain than simply finding an online service that converts them.
