Hello,
I am attempting to upgrade a handful of PCs from Windows 11 22H2 Enterprise to 23H2 using a Config Manager task sequence (TS). The PCs are in workgroups and not domain joined or attached to Entra ID and I am running Config Manager 2409.
For the Upgrade Operating System step within the TS, I am using the "Windows 11, Version 23H2 x64 2025-04B" feature update package for the update. I have come across an issue where on random PCs, the TS will install the feature update package and allow the PC to reboot several times as what usually happens for updates like this. After the reboots, the task sequence stops in a failed state.
SMSTS.log reports an unexpected reboot caused the task sequence to stop
The windows system event log shows when the TS rebooted the system for the update
and then shows trustedinstaller rebooted it a few minutes later for the update.
The last entry in smsts.log when the TS rebooted the PC was as 1:11:20p and the next entry was at 1:17:49p so there was no TS or Config Manager activity where a reboot would have interrupted it and I do not have any reboot steps in the TS around the time of the update. I would expect the TS to be aware of all reboots Windows is doing prior to when the TS starts running again but it apparently does not.
Does anyone have any thoughts how to prevent this from occurring? One of the messages in smsts.log at the failure says "Task Sequence action is not configured for retry on reboot." I looked into how to set it to retry and I found the SMSTSRetryRequested and SMSTSRebootRequested variables in the documentation at https://learn.microsoft.com/en-us/intune/configmgr/osd/understand/task-sequence-variables#SMSTSRebootRequested but both look like they do the same as the Restart Computer TS step and not actually retry the TS if it failed.
Thanks to everyone in advance.
UPDATE: After I posted this, I examined the logs from a PC where the upgrade completed with no issues. The system event log on that PC reports the same reboots as what the failed PC reported (first reboot initiated by TSManager.exe and the second reboot initiated about 5 or 6 minutes later by TrustedInstaller.exe) but SMSTS shows it picked up and ran after the 2nd reboot, did not report any external reboots, and ran to completion. I am attaching both SMSTS logs. Note the same TS was run on both PCs but both experiences different results after the Upgrade Operating System step completed and the PC rebooted to allow the upgrade to apply.
