I clarified the Servicing Stack Update. I wouldn't recommend to install it for now. For a test VM it's ok. If you're using Pro, the POSReady updates make no sense for you. If you use POSReady you're fine of course.
Yes, I finally found them. Many thanks for your assistance. It was really appreciated. I would like to thank the other posters who provided direct links. M.
I was just about to install KB4537829 after installing KB4537820, when I saw this. Does this mean that the bypass need to be reinstalled next month, or does the update break everything? M.
if the KB4537829 update is installed after the other updates, it will break the bypass, it means that the bypass will need an update so that people continue to receive ESU upates next month but there is a solution offered by @abbodi1406 which allows to uninstall KB4537829 as it's not possible to uninstall it the usual way.
