I'm trying to use W10UI to integrate updates for Windows 10 LTSB 2015 (build 10240). I have the SSU (KB5066587) and the LCU (KB5066837). The SSU installs successfully, but the LCU integration always fails with DISM error 0x800f0922. I was wondering if this is expected, or am I missing another prerequisite update? Is this version simply not supported by the script?
