In my testing, my test 1909 machines are seeing all updates except for these, even after reboots:
Windows 10 June 2021 Cumulative Rollup Update for Version 1909 (KB5003635)
June 2021 Servicing Stack Update for Windows 10 Version 1909 (KB5003710)
Both of these patches are listed in WSUS and deployed with everything else, the Office security updates and the Third Party updates from PatchMyPC. All other updates installed just fine.
These computers have the April 13, 2021 servicing stack update (SSU) (KB5001406) and also have the May 11, 2021 Servicing Stack Update for Windows 10 Version 1909 (KB5003244).
I have been deploying Windows Updates from Microsoft via WSUS for 11 years. I worked for Microsoft Technical Support from 1998 to 2004. There have been many Windows 10 versions that have come and gone. All versions that went end of life still had updates available for several months after the technical end of life date. Never yet, until now, have I seen Windows Updates fail to install when they were offered via WSUS.
As a test, I manually installed the June 2021 Servicing Stack Update for Windows 10 Version 1909 (KB5003710) downloaded from Microsoft’s Update Catalog last night on one PC that had this issue and has never before had an issue with Windows Updates.
I rebooted, then checked WSUS again for any security updates, such as KB5003635. None were found. I checked again this morning. Same issue. I installed KB5003635 manually. It went through the install, provided Installation Complete screen, rebooted, got to 98% complete, then failed, and rolled back. Windows Updates on this computer shows Windows Updates error 0x800f0922.
I took another computer, that also had this issue and had never had an issue with Windows Updates, and I manually installed the Windows 10 June 2021 Cumulative Rollup Update for Version 1909 (KB5003635) to see if it would install on a computer that did not have the June Servicing Stack Update KB5003710 installed, but had the April and May Servicing Stacks. It went through the install, rebooted, then failed, and rolled back.
I installed KB5003710 manually. I installed KB5003635 manually. It went through the install, provided Installation Complete screen, rebooted, got to 98% complete, then failed, and rolled back. Windows Updates shows error 0x800f0922.
I went into WSUS and imported KB5003710 and KB5003635 into WSUS, but it didn’t help – the updates were still not seen by my endpoints.
I took another computer, with Windows 10 20H2, and checked for updates. It installed Windows 10 June 2021 Cumulative Rollup Update for Version 20H2 (KB5003637) without issues.
I checked https://learn.microsoft.com/en-us/windows/release-health/resolved-issues-windows-10-1909 but the issues with KB5003635 are not listed there.
I think there is an issue with the updates KB5003710 and KB5003635. Could someone look into this and fix the issue? We have 5,000 computers with Windows 10 1909 that are now in the lurch. Let me know if you would like the WindowsUpdates.log, or if the issues I am seeing with the two updates could simply be fixed.
