Patchmypc does not suppress the reboot of windows on a few updates. I'm pretty sure one is Malwarebytes. Not sure what the other one is. But after installing a hand full of updates when remotely connected, I notice the computer will proceed to shut down and reboot (and disconnect me). It's annoying. So take a look at malwarebytes, I think that is one that does it.
Could you look at the application even log and system event log that should tell you what app rebooted the machine
I will the next time it happens.
I just ran patchmypc after I went from windows 8 back to a windows 7 image. It had to updates quite a few applications. Once Malwarebytes finished updating....BOOM... the computer started to shut down and reboot.
Having the same issue with the Malwarebytes update automatically restarting the computer.
It looks like the Malwarebytes installer can be run with a NORESTART switch, although I haven't had a chance to test this.
Thanks for reporting guys, This should be fixed in version 2.3.0.4 that's now available
