How to stop a mandatory reboot following SCCM software updates
We have all been there…you receive a software update and continue to
postpone the reboot as long as possible. When the reboot deadline hits
you are still not ready to reboot. This leaves you with 2 options. You
can either let the scheduled reboot take you to wonderland or follow
these instructions and stop the reboot dead in it’s tracks.
1- Open a command prompt and run shutdown /a. This
cancels the shutdown commands initiated by the SMS Agent Host. You can
rest easy knowing the SMS Agent only sends 1 reboot command per
deployment deadline.
2- Stop the SMS Agent Host service. This will close the SMS restart window that continues to nag you.
