This Security Update will absolutely not install. Upon a download where it jumps up to 100% all of a sudden it begins to install. Again slowly but suddently to 68% then 99% and then "Failed to install on 11/11/2026 - 0x800f0993". I have tried three times with same result. Then I decided to let WU show-hide tool hide the update. Next I paused WU until later in November. After a moment I asked WU to resume updates. I did not find additional updates.
The Security Update (KB5132061) (26300.9974) will stay hidden until a useful solution has been found.
This is third time I have had trouble with Security updates. A tedious, time consuming and annoying job.
Can anybody help solve the problem? - Thanks.

2026-11-11T16:16:03.8933333+00:00 For this specific Windows 11 security update, the supported self-service options in the provided material are:
- Use Settings > System > Recovery > Reinstall now under Fix problems with Windows Updates.
This process is described as not affecting files, settings, or installed apps. - Install KB5132061 manually from the Microsoft Update Catalog. For x64, this update requires the checkpoint cumulative update to be installed before the target cumulative update if it is not already present:
-
windows11.0-kb5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu -
windows11.0-kb5132061-x64_aedc878e9e078df2ec7e2cfb98dd5b21831cdbcc.msu
-
- Instead of double-clicking each MSU, place all KB5132061 MSU files for the correct architecture in the same folder such as
C:\Packages, with no other files in that folder, and install from an elevated Command Prompt:DISM /Online /Add-Package /PackagePath:c:\packages\windows11.0-KB5132061-x64_aedc878e9e078df2ec7e2cfb98dd5b21831cdbcc.msuOr from an elevated PowerShell window:Add-WindowsPackage -Online -PackagePath "c:\packages\windows11.0-KB5132061-x64_aedc878e9e078df2ec7e2cfb98dd5b21831cdbcc.msu" - If the required checkpoint cumulative update is already present, Windows will indicate that it is already installed.
- If the device is managed through WSUS, this update syncs automatically when Product = Windows 11 and Classification = Security Updates are configured.
Note: the catalog guidance states that if additional Dynamic Update packages are installed, use versions from the same release month as this update.
AI-generated content may be incorrect. Read our transparency notes for more information. - Use Settings > System > Recovery > Reinstall now under Fix problems with Windows Updates.
