Year of the Linux (Server|Desktop). Seriously. If you are in IT pls look into this (and hide your RDP server behind some VPN. No not MS RDP Gateway.)
In typical MS fashion this might be very hard to debug with the hundreds of interacting components./s
In all seriousness they reviewed their internal docs not even the code (likely because it’s extremely complex) and said fixing this would brake existing functionality. I think “some cases” is doing heavy lifting for “we know many cases, but won’t tell the bad guys out there”.
