Set SMSTSRebootDelayNext to control the restart delay after SMSTSRebootDelayAdam Leinss commented
Essentially, the way the IPU works now is most of the work is done in the "online" OS (running) vs "offline" OS (WinPE). When users use to pick operating system upgrade in Software Center, it would go offline within 15 minutes and Windows 10 would upgrade within roughly a hour. Now they they moved the bulk of migration process to the online phase which is great, except when it wants a reboot it gives the end user 30 seconds to save their work and reboot. This reboot is started by setup.exe itself and not the Restart Computer option withing the TS, so configuring any options for this step has no effect on suppressing the reboot.Adam Leinss supported this idea ·
