As part of my Post-Installation tasks, I have some additonal commands entered into HKLM\Software\Microsoft\Windows\CurrentVersion\Run to be run after first reboot. My very post-installation task reboots the computer, and then the very last Run entry is yet another reboot.

The issue I am experiencing is that the first reboot works fine, but for some minority percentage of Scripted Installs, the second reboot doesn't actually seem to happen. This seems to be a new issue.

Is there anything that would prevent the Shutdown command from being able to reboot the computer? One obvious issue could be open applications, but I have the timer parameter specified, and so it would force close any such applications. Are there any other explanations?

Are you using the Postinstall Task Converter, so that your PostInstall tasks survive the reboot?

  • My postinstall tasks are fine. The issue is that the shutdown command is failing for a subset of the machines. For instance, I run the scripted install on 30 machines, and 4 of them fail to reboot their second time. The other 26 finish perfectly.
    • That is odd. Is it only when you are pushing out 30+ at a time? Do you have a failure rate if you run only 20 or so at a time?
      • the failure rate seems to be the same for any amount of simultaneous runs. and this is something that has only recently started to happen
  • Just so I understand this correctly, you have:

    Scripted Install Deploys
    Boots into Windows
    Reboot PostInstall Task
    Items in Run key install
    Second Reboot Task

    Is that correct?
    • yup, except the second reboot task is a run key entry
      • Have you tried making the Second Entry a full Reboot task? Using the converter posted above would allow the extra tasks to persist past the first reboot.
