Since Kelly has been a fan but critical of Win10 for over a year, I'm putting this thread here rather than in Windows 10 Support. But clearly it covers what might become support issues. Kelly provides sources for those issues, as enumerated above. So his article isn't mere commentary.
I've not installed Threshold 2 so have nothing to say about it.
