I currently have build 18363.10022 from the insider slow ring installed. I did try to "upgrade" to the 1909 release build 18363.418 using the 18363.418 ISO. When running the setup.exe of 18363.418, I'm not able to keep the Personal Files and Apps, because the setup complains that this is not possible when installing an older version. The setup most likely believes that I have a new build installed because the build patch number 10022 is greater than 418. I have tried to "trick" the setup by manually changing the version numbers in the registyr key (Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion) without success. I cannot go back to a previous build as I have the build from the slow ring installed for over 10 days. Any advice?
Already been covered. You have use 18363.327 .ISO or 18363.356 .ISO for the Upgrade to work. Read the Forum Post I gave you.
Switch to RP ring and just wait until it gets .100XX patches. An inplace upgrade seems thoroughly unnecessary to me.
No, it's not covered (my build is 18363.10022) and if it is, it doesn't work. I have tried it with the 18363.356 ISO (18363.356.190908-0900.19H2_RELEASE_SVC_PROD1_CLIENTPRO_OEMRET_X64FRE_EN-US.ISO) now from the link above as well. The apps and files cannot be kept.
Then go with 18363.327 .ISO. Enthousiast has already confirmed that 18363.327 .ISO works. https://forums.mydigitallife.net/th...-18362-3-xxx-pc-19h1-2-release.79259/page-291 Post #5814 with Pics
This didn't work: 1. The 1909 EP cannot be uninstalled (at least not in my case) 2. But I was able to uninstall a cumulative update which brought the version number down to 18362.10019 3. Now I was able to install 18363.356 .ISO 4. The in-place upgrade went fine, without any errors. Meaning the old Windows build was not restored and the "update" was actually successful. 5. After the restart the build number is still at 18362.10019. The kernel32.dll version number is 18362.10000 6. So I do not believe things went well. I also tried it with the 18363.418 ISO and I see the same behavior.
I don't quite understand how the in-place upgrade/downgrade can succeed but all the system files are still at the same version.
Because of the mess MSFT made with releasing a mock build, even the original MSFT iso can't figure it out, that's why it doesn't offer the other keeping options. And those who installed the 1909 EP on 18362.10022, bumping it to 18363.10022, made it even more difficult, specially when the 1909 EP can't be uninstalled.
