[Please note that this question is about upgrade Windows "Enterprise".] The free Windows 10 upgrade link that Microsoft provides doesn't work for Windows Enterprise. I think you should do it the old way -- with an optical disc. But even with an optical disc - which my organization has provided -, I'm at a loss how to upgrade it on my virtual machine. My IT people don't have a clue either. I do have a Windows 10 Enterprise CD-Rom, but where do I go from here in order to upgrade my Windows 7 on Parallels?
Hi WonB, we suggest you to follow this article and then check with your IT team for upgrading to Windows 10 Enterprise.
