OS Build # 19045.3930. Update Troubleshoot tool repair but it does not help. MS Windows Update Catalog does not have the update. Other updates all went through without any trouble. This is a brand new update. Is this a known issue? Is there a resolution specific to this update? (Please do not copy and paste standard procedure)

None of the procedures in the above list will work. You have to expand the Recovery Environment partition and reconfigure it afterwards so that it is exactly like it was before, only larger. Then the windows update will install successfully. Doing all this requires computer skills light years beyond what the average PC owner has. It took me 9 hours to figure this out, while going down many dead-end paths, and I worked in IT for over 50 years. We already know about it. You did not read here or I dont know what are you writing about. But I already replay to people before here --> Your partition "win re" must be at least 1G, I created my winre with 2G and that is OK too.

(KB5034441) I have the same problem, I hope I can fix this soon.

Try to increase recovery partition to 1GB following the guide provided my Microsoft at Resize Recovery partition and just change the size from 250(in the article) to 1024 and restart and try updating.

<removed by Moderator - COC Violation> But to be fair, I did every each step they suggest - it didnt solved problem :) Its always the same "turn on and off" mumbo jumbo talk with them. Just ignore the update, and wait. I got OCD and I like to have everything done perfectly, so put yourself in my place lmao.

I concur. I also have MULTIPLE machines running Without bitlocker, and every single one of them has failed to install. All display the error: 0X80070643 Update History shows multiple attempts/failures -- for THIS update -- but success for three others: (KB5033733) (KB5034275) and (KB5034122) Security and Maintenance Reliability report <Control Panel\All Control Panel Items\Security and Maintenance> also shows Success for the three above as well as the Failure for KB5034441 .. .. HOWEVER--> when I click 'View technical details' link in that report, I get the following: Installation Failure: Windows failed to install the following update with error 0x8024200B: 2024-01 Security Update for Windows 10 Version 22H2 for x64-based Systems (KB5034441). NOTE: I have forced a new Download but still receive the error on this update (admittedly, working on the 'fix' for only ONE of my machines at this point - to limit the < removed >)
