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.stopsmsshutdown04

Have a great day!
