Using an old windows 7 upgrade

[UMRminer11]

I purchased a computer with a windows 7 upgrade right before 7 came out. Just recently I purchased a new computer and wanted to reuse that code. However, the website (windows7upgradeoption.com) seems not to work anymore. Is there another way to upgrade my computer?
