W10UI v5.4 Added support for multi-versioned updates, to avoid skipping new version if old version already installed e.g. KB4469342 17763.165 & KB4469342 17763.167
It's the third time that I have to do an in place upgrade to be able to install the latest update on Server 2019. No problem in W10 1809, but on Server 2019 everything ends apparently well, the server is updated correctly and works perfectly, but when a new CU update is released, it always fail with Dism error 50. I never saw that behavior before, so I guess there is something connected to the new update format which apparently isn't as rock solid as the older one. If anyone has a clue on that behavior he is welcome.
Reset base after installing a CU? I always do that given I always have an older copy of the vhdx stored somewhere, and rolling back is slower than swapping a vhdx.
Do I need to do that everytime I install CU? I feel like my computer gradually become slower and my disk is becoming full too after every update.
Full resetbase is disabled by default on windows, /startcomponentcleanup is the best way to go, /resetbase broke windows functionality (ResetPC).
