Hi, your Dell OptiPlex 790 came with a Windows Pro COA, but you have a Home Premium license. You can still use the prebuilt Dell code on the Microsoft site if you install Windows Pro through another method, as long as you follow the installation instructions. Otherwise, upgrading to Home Premium will be necessary.
Reach out to Microsoft Support through Live Chat for a Windows version compatible with Dell COAs.
I have a version but I'm not sure if it's damaged. Where might you find another copy?
