If you upgraded to Windows 10 over an existing system, did you install the latest version of iTunes AFTER the Windows upgrade or before? If it was before, you may want to install iTunes again, after downloading the latest version from Apple.
Seeing "Do not disconnect" on the iPod's screen is good. That means the iPod is seeing a data connection. What did you mean by "safe mode" in your previous post? Is that the "Do not disconnect" message on iPod's screen, or something different?
In iTunes, the iPod appears as a small device button on the horizontal bar that goes across the iTunes window. In your previous post, you said, "its erased everything." Does that mean iTunes recognized the iPod, and asked you to do a Restore or take some other action that erased the iPod?
