Losing your Microsoft Office product key (the Office CD key) might not seem like a big deal but it can quickly become one if you end up needing it for some reason.
You must have the product key that came with Microsoft Office 2007, Office 2003, or whatever version of Office you have before you'll be able to reinstall the suite.
It's very simple actually. Just download a free key finder program and have it automatically search your computer for your Microsoft Office product key (Office CD key).
These key finder programs are great for finding lost keys from Microsoft Office versions like Microsoft Office 2010, Microsoft Office 2007, Microsoft Office 2003, Microsoft Office XP, and even many older Office versions. Plus, these key finder programs also find CD keys for other software programs and even many operating systems!
Don't like to install unfamiliar software from the Internet? Unfortunately, the Microsoft Office product key is encrypted in the Windows Registry so finding it manually is next to impossible. You will need to use one of the product key finder programs to locate it.
If you still can't find your Microsoft Office product key, you may need to purchase your particular version of MS Office all over again.
