A: IT pros, IT decision makers, and developers who are looking to test their hardware, software, and deployment strategies on Windows 7 can download the Windows 7 Enterprise 90-Day Trial. You must correctly fill-out a survey to gain access to the download. Incorrect or incomplete surveys will be denied access to download Windows 7 Enterprise 90-Day Trial. Again, if you already have access to Windows 7 bits through MSDN or TechNet, or are an existing Software Assurance customer, you do not need to download this trial and already have access to the Windows 7 RTM without a timeout period
