When ever you set up a new PC, it is always good to update the software. After all, it has been several months since the PC was built. So, I went out to the manufacturers website to download the latest software updates.
The first thing that they asked me for was the model number of the machine. No problem, I am sure the number is on the outside of the box. But, I looked. No number. Next, I checked the outside of the PC. It revealed many numbers, but not the ones that I needed.
Eventually, I checked the receipt. I found the number and entered it. Success!!
