What are OEM pre-installation tools

[Halbard]

I just purchased a windows 10 OEM system builder DVD from amazon, for use on a custom built PC, and am unsure of what this bit of text on the front of the DVD package means:
"The software is intended for preinstallation on the hard drive of a fully assemble computer syste, using the OEM pre-installation tools. For information about using OEM pre-installation tools, see www.microsoft.com/oem/opk."
Since the link leads to an error message that the page cannot be found, what are OEM preinstallation tools, and what do they do? Also, since the web page is missing, does it mean what I bought is a scam?

FWIW I've installed a lot of OEM versions of Windows 7 and never had to deal with any kind of pre-installation packs. I did have to make sure I had all the right drivers from the makers of my motherboard and any additional hardware I added. With Windows 10 though I just download the insider builds on my desktops, and my laptop came with 10 pre-installed.

Good luck.
