The site mentioned in this video has moved to this new URL (https://b00merang-project.github.io/linux-themes) the old URL will tell you that this is the new URL. I have archived the old sites message so that you and future readers can verify that this is the new link rather than trust. https://archive.ph/dAHTR
You will notice that this site has more themes than just windows 7 and the installation for them I assume would be the same so if you see something that interests you, you should check that out as well.
