What 1909 enablement package update is that?

It currently does 2 things. It changes 18362 to 18363 & changes ver. 1903 to 1909.

Yes there will be a new .ISO when released to the General Public.

 

Ok thanks

 

So does using the 'Cleanup System Image' and 'Resetbase:Yes' options in W10UI7.1 affect updates working?

 

ResetBase is disabled for 18362, even if you choose it, so no effect

enabling cleanup option may cause failure on future CUs (the error actually come from the CU themselves not the cleanup, specially Release Preview updates)
so the safe side would be not to enable it, or only enable it for patch tuesday cumulative update (i.e. the one released next tuesday)

 

That's the cosmetic things
the real thing it does is enable feature id 20455539

 

Just what is Feature ID 20455539 ?

 

you could try to install 18362.329 (without kb4517245), then see if mach2 can enable the 1909 features

Code:

mach2.exe enable 20455539

 

So am I safe to assume converting the index wim to esd to save space will have no adverse affect on updates?

 

Not at all, esd is just solid wim

 

Just found an issue with the W10 v1909 enablement package (Windows10.0-KB4517245-x86.cab), when this package is integrated it wrongly assigns the image architecture as amd64 in this particular key.

Original Key

Code:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion]
"BuildLabEx"="18362.1.x86fre.19h1_release.190318-1202"

Changed to

Code:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion]
"BuildLabEx"="18362.1.amd64fre.19h1_release.190318-1202"

 

I somehow managed to be on 1903 10.0.18362.10019 even though the Enablement Package is installed

 

That's possible, with the enablement package, installed on 10019, it will only enable features (on 10019 already enabled by default). But it won't bump the build to 18363.

 

The manifests that bump the build to 18363 are contained within kb4512941 (and all future 1903 CUs)

Enablement Package only install those manifests
