This is how we have scheduled reboots in the past when needed for patch management. We encourage users to shut down at the end of the day, for those that don't, the next morning they used to be prompted to reboot with option to defer 10 mins (machine goes to sleep for 3am restart due, then next morning would be prompted when they woke machine up).
Client shows
CMS settings are set like they were prior to upgrade
However, the prompt to reboot/defer has been broken since the 7.5 upgrade, users never see it when their machines wake up, and the client scheduled reboot time just moves to the next day. Did some connect searches but not finding anything. Anyone else seen this issue or suggestions of what to try? Used to work great for us, and really was one of the major bonuses of patching with CMS over SCCM.
