Notice, as expected & predicted, today's update for Defender went without a problem & is listed in Update History... all is back to normal. More "fun with 'puters" 😁 Cheers, Drew ![](https://learn-attachment.microsoft.com/api/attachments/1236b593-efd9-40a6-a9a0-a7d83f102af0?platform=QnA

UPDATE 4/28: We are starting to roll out Cumulative Update Build 21364.1011 (KB5003402). This update does not include anything new and is designed to test our servicing pipeline including our ability to release servicing updates on top of previous servicing updates. This DOES NOT include any fixes for the known issues listed below.

downloaded fairly quickly on my Sony Vaio, but took its time installing - about 10 minutes. Required a restart afterwards, which again took a long time, with the spinning circle showing

Thanks CK. First attempt failed (KB5001030) -Error 0x80092004

Installed fine for me but as expected had no impact. KN5001030 - Error 0x80092004 remains as dose USB printing error of course. Hopefully, this was a needed plumbing update before they roll out the next dev update (today?).

CO-Release Build 21364 to Dev Channel + KB5003397 + KB5003402 to .1011
