Today I upgraded my laptop to W10 2004, it has kes11.3.0.773 but no network agent installed. After the upgrade I got a exclamation mark on KES icon on system tray stating that a restart was requiried to complete a kes update and after restarting my laptop everything was fine. On the other hand, my managed computers have kes11.3.0.773 and network agent 12.0.0.7734 they are under KSC12 policies. After upgrading two computers to W10 2004, KES icon was grayed out with little exclamation symbol on it, so I opened kes and showed only 4 of 15 protection components enabled, so I tried to started them but failed, then I tried to uninstall kes but I got “Error 1921: cannot stop kneps service...” so I cancelled uninstallation and this time I did a “repair” instead uninstall and everything was working fine now. I did this on the two computers and on both got the same good results. I hope this helps :)
