I've downloaded 2025-12 Security Update (KB5072033) (26200.7462) three times, and each time it fails to install. Any suggestions or is this a problem with the update. My computer is a week old.

    About eight days ago, I started trying to install Windows 11 security update KB5072033 (operating system version 26200.7462 / 26100.7462), but the installation repeatedly failed, frequently displaying the message "Update in progress, please keep your computer powered on." Even after restarting, the update could not complete. From December 11th to 12th, 2025, the installation failed for two consecutive days, with error codes 0x800f0991 and 0x80070002 respectively. During this period, the update temporarily disappeared from the "Quality Updates" list and was replaced by the Windows 11 24H2 fix release. At the same time, a folder named $WINDOWS.BT appeared on the C drive; the download progress once approached 100%, then reset to 0% after restarting. Until last night, after the fix release slowly progressed, the update switched back to KB5072033 and finally successfully downloaded, installed, and completed, resolving the problem.

    螢幕擷取畫面 2025-12-18 225818 It's appeared again, downloading KB5072033 (OS Builds 26200.7462 and 26100.7462). Still running. Praying it will install successfully.

    I did have the same issue with downloading kb5072033 from the catalog.update.microsoft.com for offline install. I could fix it by downloading the mentioned kb5043080 also and placing both hotfixes in a single directory (C:\Temp\Hotfix). Now start a command prompt as administrator and run this command (notice the Packagepath)

    C:\Windows\System32\Dism.exe /Online /NoRestart /Add-Package /PackagePath:C:\Temp\Hotfix /IgnoreCheck Ignore the error on the first hotfix. Unfortunately, I need to run hotfix kb5072033 twice (after reboot) to get the SSU and hotfix installed, so extracting the 4 GB again! So it takes a while. Check installation with Powershell command: Get-Hotfix
