There is the Enterprise trial which is a 90 day trial available here: [URL] Unfortunately the Enterprise trial will not accept your product key so you would have to clean install twice. [URL] If you want Windows 8.1 then its best to test the system with the trial to see how well it perform opposed to opening your Windows 8.1 retail box because if you open the box and it doesn't work well its value for resale will go down and/or you may be unable to send it back for a refund. Dell are extremely unlikely to release driver sets for that model for Windows 8.1. I have some experience at listing unofficial driver sets and its highly likely the system will perform well with the ones I have listed.
