95twr With UWF running at all times, I need to schedule a few hours per month with UWF turn off to install Windows update and perform component store cleanup after updates.

These are low powered devices with low and slow eMMC storage. Install of monthly 1Gb to 1.6 Gb cumulative updates from LTSC 1507/1607 + component store cleanup can take longer than re-image the device.

LTSC 1809 seems improve a bit yet this is far from efficient.

null null Thanks for sharing the feedback. If possible, we’d like to clarify a few items to help us better understand the issue here.

For the update process, are you mainly concerned about the update download taking most of the time or the update installation time? Or it is the overall end to end process taking long?
Are you applying updates to these LTSC devices every month? Since you mentioned about UWF, assuming you are using UWF servicing mode as documented here: https://docs.microsoft.com/en-us/windows-hardware/customize/enterprise/service-uwf-protected-devices?

Would like to understand a bit more details of the issue you experienced and connect with you offline. Please message me if you would like to connect. Thanks.

I am applying Windows update every month during servicing window. WinSXS needs to be cleanup to save disk space, as well as avoiding automatic WinSxS cleanup task schedule kicks in and use up the UWF ram overlay outside servicing window.
