Typically these aborted/postponed with the dreaded 0x8007002 in the "control panel" user interface.Īlso, if there's some other (typically non-MSFT) app that invoked TiWorker for servicing, not Windows update, you won't get anything in that log, as far as I can tell. just for checking/installing the Windows Defender definition updates you may get slightly over 1000 lines of log output.Īfter a bit more experimenting (with an old enough PC that uses an HDD so things take a while), the "firehose" log does have a substantial limitation: if there's an old task started that takes a long time to complete but prints nothing as it progresses, it becomes very hard to find in the log if Windows attempts newer tasks, but you get some clue that the new tasks get postponed or error.
