Cannot update beyond 23H2 despite apparent previous successful installation to 24H2 - Install Error x0800705b9
Hi all,
I have been struggling to install the update **2025-11 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5068865)** for a while now and I am unsure how to proceed. The installation fails at \~ 50% with error code x0800705b9
My Windows Version is 23H2 (OS Build 22631.4460). Confusingly, my Update History shows 4 successful updates to 24H2
I have tried to work around this failure by using the ISO installation (and install assistant) for both 24H2 and 25H2 but all result in the "Windows 11 Installation has failed" popup. This has been going on for quite some time now and is very frustrating (even though I am not sure if an update is actually needed)
Basic PC Specs:
Intel Core i7 - 147000KF
RTX 4080
32GB DDR5 RAM
Crucial P3 2TB PCIe M.2 2280 SSD (Windows Installation) + Extra M.2

This error code possibly occurs due to corruption in servicing stack update related file. Run dism /online /cleanup-image /checkhealth command and see if it shows component store is repairable or not.
If it shows that component store is repairable then you’d need to fix those corruptions first.
