I’ve received it 3 days back at home & at work WSUS server is yet to recognize this update! So, I removed my box from WSUS & tried to get the same using Windows Update. Once after restarting my domain joined computer, I was presented the 23H2 update, however, will not download and always ended up throwing the error “0x80246019”
A quick search landed me on multiple threads and the one worked for me was, disabling the “Get the latest updates as soon as they’re available”. Once after turning it off, downloaded completed successfully and within 3-4 minutes my box was upgraded to 23H2.
(Based on organization policy, you may find this switch not enabled for domain joined computers)
