Latest Update: November 29, 2019

Even though Windows 10 1909 is only a small update compared to 1903 (NTK 1903) I have created this list with interesting links for IT Pros regarding this release. A place where I can store articles about new features, settings or bugs. I will update the post with new content as soon as I find it.
If you find something new before me or if I missed anything important please write a comment or send me a message via Twitter.
