I'm facing the black screen issues after login in a Windows server 2012 R2 through RDP. As referred from MS blog (https://social.technet.microsoft.com/Forums/en-US/31b681c5-3658-45a5-8158-a0a0f967c4a2/rdp-screen-goes-black-after-successful-remote-login?forum=winserverTS) I have tried to start task manager with alt+ctrl+del keys, but only two options (Lock and Sign out) are available. I can login the system locally. In task manager only 3 processes are running of the RDP user. My observation are there in the attached screen-shots. I have installed the new patches KB4021558, 4022717 and 4022726. Then I have rebooted the server. Since that reboot, issue started. Then I have uninstalled the patches, but unfortunately issue still persists on server.
