  1. I also installed
    windows enterprise 1809 evaluation 90 days & applied patch. It was working perfectly.
    It was working as single user with many multisession at a time, (multi login single user RDP as it is normal with windows server 2016/2008)
    It was also working as different terminal services users with multisession to a single machine.
    I see there updates on machine were installed and then single user with multiple session is no longer working. I don’t cause the issue. Update KB4487044 / KB4470755 / KB4483452 installed on 13-Feb-2019.
    Later i uninstalled those two KB but still the multi login/ simultaneously single user with terminal services for different sessions didn’t worked. (the kb4470788 was not removable)
    I used two things to make it happened
    1.) HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Terminal Server fSingleSessionPerUser key Change the key value from 1 to 0
    2.) 1.52MB
    Can some one assist to make again windows 10 pro or entp 1809 multi-logging same user with differnt concurrent sessions to single host locally or remotely as I done previously so that I get updates as well.
