True, I knew about installing KB2919355, although the original SSU was KB2919442. My enquiry was referring to going to the mum of KB3021910, editing it and uninstalling KB3021910, AFTER later SSU like KB4524445 is installed. Are there any adverse effects on an online installation in this case, or it is better to leave KB3021910 installed as better practice regardless? This is relevant as in such a case when a later GM SSU is installed and the RTM SSU is not (because it was uninstalled, this being done against the official Microsoft implementation), KB3021910 is not offered and may not even be possible to install manually as far as I am aware. I am not a current user of Windows 8.1, but this discussion is useful as well in relation to Windows Server 2012 R2.
Maybe not massive effect, but CBS will flag and report the image version as it was vanilla 6.3.9600.17031 (KB2919355 version) this can mess up update servicing think of it like Win7 SP1, which have baseline SSU KB976902 someone should test this scenario but i think CBS is smarter than WU, and it will allow KB3021910 as applicable
Thanks, it is clear now after explaining the analogy with SSU KB976902 (KB2533552). For Windows 8.1/2012 R2, KB2919442 would be closer to KB2533552, but I understand that KB3021910 is better and covers everything that the earlier SSU RTM was doing. If I remember well, KB3021910 was re-released to allow KB2919355, as the first release still required an earlier SSU for KB2919355.
Confirmed that CBS is smarted than WU I installed with DISM (online image) KB2919442 on top of a Windows 2012 R2 system fully patched to December 2019. This system already has KB3021910 and the later SSU required installed.
Just to be clear, Is it enough to only have KB2919442 and KB4524445 in the updated offline image? The reason I ask is because I tried installing KB3021910 without dism on the online installed image and the msu indicated it's not applicable to my system. Same goes for KB2975061.
It may be enough and I have all reasons to trust @abbodi1406 but what stops you from using DISM and install whichever SSU you wish? Let's say install KB2919442 to satisfy the KB2919355 because they come bundled at least in WSUS and install KB3021910 which is the last RTM SSU as I learned here and confirmed by checking the C:\Windows\servicing\Packages folder. The choice is yours.
Get WHDownloader, update the lists, select "Windows8.1-Update3" and then you'll have the answer (and can get the updates easily).
I already know WHDownloader and how to use it, but my concern is Whether I should include all the updates WHDownloader offers. If I have to do so about 1 GB amount of updates have to be integrated. am I right?
At least once a month, abbodi1406 reviews the list of updates in WHDownloader- adds the newest; removes the unneeded. So everything listed in there is current. What's needed is up to you to decide- you may choose not to include some, like the ones in the RSAT category or MediaFeaturePack or the ones that are superseded but still shown as needed by Windows Update (in the WU.Satisfy category). And some can't be integrated and need to be installed online (in the Do.Not.Integrate category). It's best to just download everything then review the categories and read the various .TXT files that abbodi1406 included. They contain more info on everything.
@abbodi1406 Your sigs for W7 and W8 show KB4072650 (HyperVIntegrationServices) as added for 2020-03. Is this a newer version than Windows8.1-KB4072650-x64-r2.cab (6.3.9600.19456) and if so, do you have a download link for it?
@adric, info about KB4072650 is here: https://forums.mydigitallife.net/threads/whdownloader-support-and-chat.44645/page-144#post-1581762 and here: https://forums.mydigitallife.net/threads/whdownloader-support-and-chat.44645/page-144#post-1581982
the Windows6.2-HyperV cab is identical to the cab I already have (r2). Not sure what to make of the Windows6.x-HyperV cab which has less files. A bit confusing for me.
