What I'm hearing is that to use Windows 10 I should contact IT and ask them to provide me what should be publicly available. Below the list from Dell below shows no support for Windows 10, I did talk to someone on their support line who told me there is no support for Windows 10 yet. I did contact my IT department whose reply is you don't upgrade the day the software is released -- in my case my Toshiba laptop dropped and the screen cracked so I purchased a new one with Windows 8.1 - Windows 8.1 requires switching between start and desktop and using search to get anything done, fills the screen with spam applications, requires registering to use the computer OOB, and is so counter-intuitive, difficult to use, that I took a huge risk and did the upgrade on a new system.
