Warning "A computer restart is recommended" after client install in Remote Management Posted March 21, 2017 37 minutes ago, Marcos said: We strongly recommend restarting the OS as soon as possible after upgrade. Otherwise old drivers will remain loaded until the next restart which might cause issues with a new ekrn. E.g. on servers the system could hang because the new ekrn could not verify older drivers due to a change in the signature a few months ago. On Windows 10 a shutdown with "Fast start" enabled is not an actual shutdown but a kinda hibernation (https://www.tenforums.com/tutorials/4189-turn-off-fast-startup-windows-10-a.html). I think that may be that. Thank You.
