The recent iso's are badly updated:
- more than one CU integrated for w/e reason
- all the telemetry is most probably in there
- the size of a single index iso is 5GB+, which is roughly the same as a 64-bit AIO with integrated updates, .net 4.8, visual c++ runtimes and directx
The common joke is those iso's were made by newbie interns and are really highly NOT recommended.
Just download a clean media refresh iso, use simplix updatepack on it(download abbodi's addons and put them next to the updatepack if you want). You'll achieve a much better result.

They are indeed badly and unprofessionally made. Looks like somebody installed Windows 7,  installed updates, syspreped it and added it back to the WIM file. I would use the original Windows 7 ISOs from 2011.

Patch test for 32-bit Windows 7 ISOs
This is not the tutorial about how to apply the patch, this is very basic. 1. Download xdeltaUI here and extract the archive. 2. Select the patch you have just downloaded and the generic ISO as source file. 3. Select output file, press "Patch" and wait until it finishes patching.
Note: This is a test and there is no promise that it will work. Please verify the hashes after patching finishes. Hashes of original ISOs are here. Please report any problems to me and I will try my best to fix it up. Do NOT tell me that the generic ISO doesn't work.
Once I get all the patches created, I will start a new topic with proper instructions.

Please PM me for the generic ISO (source file).
