We have recently upgraded all systems to ZCM 10.3 but it seems that certain XP patches are causing our PCs to reboot after installation.

Even though I have put this thread in Patch management, I also noticed one instance of an msi bundle install causing it as well.

So it might be MSI's in general. It's just that more often than not it's patches.
So far this week my machine has rebooted 3 times. Some users today have had it reboot twice todays after successive patch installs.

We really need a way to suppress reboots after any patch/bundle install because it's giving users no warning and they are losing work.
