Creator NXT3 and NXT 3 Pro are shown on the list HERE as compatible with Windows 10.
Although on other pages such as this, it has been replaced by NXT4 and NXT 4 Pro and so NXT 3 doesn't appear any more.
(What you see depends on where you are in the world, and where the page redirects you to.)
Roxio hasn't told us if this means that the NXT 3 family is no longer compatible with Windows 10, or if they have just "updated" the list to include the latest version. I suspect they should have added the NXT 4 family instead of replacing the NXT 3.
