MicrosoftHi David_Guyer thanks for further clarification. On my behalf I think I got the message right. My examples point out that the update process, despite the efforts in reducing size, which was great and successful you see the update Installation time takes too long. And as you said it cannot be paused and continued but needs to restart from scratch. This is valid for all updates including in-place updates to a newer release.
I hope that my ideas help to understand to very practical part out there, home and business, old or modern update management. It's all valid for each scenario that the impact of updates and duration should be improved with my given Inspirations.
so that a device can reboot while the user is away
This is valid in most of the cases. If a user or the system picks restart or shutdown and install updates and you use an unlock PIN for Bitlocker this concept doesn't work. It's waiting for the PIN in any case. Thankfully WinRE will shut down the system after a time when no PIN is entered.
