Currently, Microsoft has stopped publishing delta updates for Windows 10, leaving only large Cumulative Updates (LCUs) containing all the fixes since the main build was released. Large updates increase traffic and the time it takes to install them. Nevertheless, a simple method was discovered that allows me to make a delta update from a cumulative update, containing only the components changed from the previous update. In this thread, I will post deltas from the updates that have been released.
Perhaps You would start with introducing yourself and making it clear to everyone why we should trust the wonderful services you offer. So far, I have not known anything about you, but when I read your profile, I can find that you use Avast, which makes me personally seriously doubt in the home crafting innovations that you recommend. Where are your previous works published?
It's my first work about Windows. I can post the script that generates the updates. Also, anyone can unpack the archives that I will publish and verify the digital signatures of the files with the original. You found information that is over 10 years old. I haven't used Avast for a long time.
I would start with the 2015 and 2016 LTSB updates, already going to 2GB, Win 11 22H2 LCU now is at: Code: Name: windows11.0-kb5018427-x64_LCU_674.1.8.msu Size: 254418489 bytes (242 MiB) And is it really a good idea to "delta" rp updates (.675)? Considering the full versions already have enough problems installing?
If you would like delta updates for a specific version, I could generate them. Maybe someone will need this.
There is no way to inspect differences outside installing it (hopefully on a vm) because it's delta-compressed. Furthermore, not all files involved naturally carry a digital signature. And even if digitally signed, a previous version with a certain vulnerability could replace the intended one and not trip sfc. It would take considerable effort to make sure the end result is legit, like maintaining tables of versions + hashes / signatures of the resulting files (microsoft used to provide that themselves somewhere in the update foot notes). Far more effort than downloading a larger cumulative update from microsoft, where the container itself is digitally signed. Likely good intentions, but these are problematic. What would be usable in MDL fashion is some sort of script that everyone could use to generate it. And even then, microsoft themselves go for the monolithic approach to prevent update failures, like Enthousiast said. With some of these LCU's being ridiculous large for couple of years now, they should really just refresh the ESD's. But they don't, probably because the original MCT programmer left and the new-blood devs they got now can't patch in support for 4GB+
Windows 11 22H2 Build 22621.674 (x64) Pro incl Office 2021 en-US October 2022 thats homebrew thrown together stuff and made into an iso so can do more harm than good
@Kesantielu As suggested by @AveYo, we would really appreciate if you actually post the script/know-how of the delta generation method instead of posting the ready-to-use deltas.
The script needs some generalization before I can publish it. It turns out that no one needs ready-made deltas?..
