I notice this happening all the time with the 1809 version, LTSC desktop and/or server when I install an update outside of WU, like WSUS or manual installation of msu or cab and scanning with WUMT against WU after the installation. The server in particular has something to object to the installation and many times the WU offering actually fails either repeatedly or only once after which is no longer offered. Nothing to do with the distribution media of the original installation obviously.
Related to what people are talking about here.... You can also sometimes cause this to happen if you manually clean out your LCU folder. If you have been installing CUs for many many months, the LCU folder gets absolutely huge so people sometimes delete the contents. If you do this, sometimes the last CU will be re-offered and its LCU folder will be recreated.
I can't figure out right now, is this black humor or do you really mean it? Black humor is of course good, but it is not suitable for use everywhere.
He is correct about that, the only thing is that this doesn't relate to what the original situation was, after installing updates for many months is not right after install.
Not sure what you mean. If you have been in IT for a long time you have seen countless cases of people with this exact line of thinking: "folder huge" "don't know folder" "delete folder"
Its the lack of any CUs unpacked in the LCU folder in both cases triggering the same re-offer. It is a different path to the same conclusion.
The situation "right after install the already present lcu get's re-offered" is quite a big difference to a long running install re-offering a lcu, which btw is for the same reason: updating something that has changed at fod/language components.
I don't think we are on the same page because this is really quite simple. OS on current build with updates integrated, fresh install -> current CU is re-downloaded and unpacked to LCU, no reboot is required. OS on current build with updates installed, LCU folder is deleted -> current CU is re-downloaded and unpacked to LCU, no reboot is required. The only thing that is required to see this is to have the LCU folder completely empty and manually checking WU.
You're completely wrong, no way download the same lcu and unpack by itself. Every new CUs I download it manually and install/integrate by dism or wsus whatever, then run dism with two arguments '/StartComponentCleanup /ResetBase' After this run this script by nsudo. Code: @echo off set "LCU=%SystemRoot%\servicing\LCU" if exist "%LCU%" ( echo.Deleting '%LCU%'. rmdir /s /q "%LCU%" echo.Folder '%LCU%' has been deleted. ) else ( echo.Folder '%LCU%' not found. ) pause exit Everything is OK.
This doesn't seem to happen for all, i showed one probable cause but seems for that situation the lcu was not needed. Here you caused it yourself and then there is no mystery about it why it's occurring. Yes, the deleting of the LCU folder can cause the need for redownloading it when it's needed for updating changed components.
This is an interesting observation, but generally speaking, if things are properly done and the cleanup is performed using supported methods, there should be no need for manual cleanup of the LCU folder. At least in theory although we all know things are not always as smooth as they are supposed to be.
Actually sometimes the LCU folder is not getting updated correctly for some reason. It is in fact a symptom of a problem and not the root cause, but the problem may also be created artificially by deleting the contents of the LCU folder?
Retired, its just a hobby now. Finding corner case issues is kind of fun actually. Either way its not just me reporting this CU re-offer so by definition, its not just me. This strange glitch quite literally just unpacks the current CU into the LCU folder so other than taking up disk space, it is completely harmless. Since this glitch does not require a reboot, the vast majority of people that experience it would never even know that it happened. The other glitch I am observing is that some of you guys care a heck of a lot about certain ithings, not sure that one will ever get patched though.
You can definitely create it artificially. There was a debate about deleting that folder to save space and MS reps were claiming that it might break things so I tested it out to see what broke. The only thing that I observed was that sometimes the latest CU was re-offered and unpacked into LCU. If I am not mistaken, doing a Windows updates cleanup will delete all but the last CU from LCU so it makes sense that you are not supposed to actually delete all of them, certainly not manually.
