Product and CD Keys in Microsoft Office

I've seen many questions in forums and in the newsgroups asking where to get a product key or CD key, or how to repair an installation without a CD.

Bottom line:

• If you don't have the CD, you need to get one.
• If you did not purchase the software, then you should.
• If you lost or broke the CD, you should contact Microsoft for a replacement.

Please don't ask experts to assist you in installing or repairing software when you don't have the necessary disks.
