What worked for me was to download the KB5132061 msu file -
Reboot the computer.
Double click on the downloaded msu file to install the update.
Latest update won't install

This update downloaded but for over an hour it just keeps on saying that it's installing without doing so.

soccerfun22-3095 0 Reputation points2026-11-11T01:18:36.4533333+00:00 I have same problem.--I had to perform the first two steps below in the "AI answer" to get it to work. My computer was downloading the update but was not installing it.
The second step below was what solved my problem.2. Clear the downloaded update cache
This removes downloaded update files, not installed updates.
- Press Win+R, enter
services.msc, and press Enter. - Right-click Windows Update, then select Stop.
- Open File Explorer and go to:
C:\Windows\SoftwareDistribution - Delete the contents of that folder.
- Return to Services, right-click Windows Update, and select Start.
- Restart the PC and check for updates again. [^3^](https://support.microsoft.com/windows/deployment/updates-lifecycle/troubleshoot-problems-updating-windows#repair-hard-drive-errors"Windows 11")
- Press Win+R, enter

2026-11-11T15:42:33.86+00:00 That didn't work for me either as I suspect it wouldn't for most users whose updates are failing. In fact, I downloaded and tried to install the msu file and it failed just like the regular update method. Moreover, the troubleshooter also failed stating it could not run the diagnostic. I should also state that the msu download is fine but the install of the msu file goes all the way through and then states the "update was not installed". So the issue is not with the download via Windows Update or manual download, it is with the installation.

2026-11-11T21:56:06.03+00:00 My reply was to the OP who had the same issue I had where the update never completes. I had the same problem on two installations and what I posted worked. Obviously the issue you have is for the same KB update but likely a different bug in the update.

FiKRET TÜREDİ 25 Reputation points2026-11-11T12:08:47.5466667+00:00 That is exactly what I did. I tried both downloading and installing it manually, as well as using Windows Update. The result is that all the computers in my home are showing the same error. And it’s not just me—it could be thousands, perhaps even millions of other people. This is the first time in the last six months that I’ve encountered an issue like this across all my computers. Please help. https://www.youtube.com/watch?v=Gh9eW902CKo

First please report the issue in the Feedback Hub
using WIN+F so they get diagnostics.
Also, are any of you using Windows Sandbox?
If you are, disable it. I've read from some that
that may be the issue.

2026-11-11T17:07:31.54+00:00 No, I'm not using the sandbox and I'm speculating that many (probably the vast majority of) others aren't either. So that's not a great suggestion. Moreover, I really can't comprehend why Microsoft needs diagnostics from my machine when they likely have hundreds, if not thousands, of employees who can't get KB5132061 installed on their machines either. They NEED to FIX the update file. I have now officially tried EVERYTHING including restoring an image from a day ago that did not contain any of the other updates. NOT WORKING!

2026-11-11T17:11:19.1466667+00:00 It is a suggestion because other Mods have already discussed it.
So you've seen FB that employees are having issues with this update?
Feedback is important, but your choice.

2026-11-11T17:19:26.2566667+00:00 I'm sure they have plenty of feedback at this point in the sense that they are AWARE there is an issue with KB5132061. It would be unfathomable to believe they need more data points to resolve this. The hub also doesn't work unless you have it installed (which I do not).

2026-11-11T20:45:20.5566667+00:00 Thank you to everyone who replied. I am happy to report that I finally overcame my problem
by doing a system restore and then with fingers crossed did another download etc.
It took a while but all is now OK. I should have tried the system restore first but being old
I didn't think ot that until later.

Leon Almeida Coutinho 10 Reputation points2026-11-11T21:58:32.0233333+00:00 Olá todos !
Estou com o mesmo problema(KB5132061) (26300.9974) Erro de instalação - 0x800f081f
Já tentei fazer o download na versão 25h2 e agora na 26h2, fiz o procedimento de apagar as pastas Temp %Temp% Prefech e Recent ... apaguei a pasta SoftwareDistribution, e mesmo erro ocorre, ela baixa mas não instala. E tentei pelo catálogo e a mesma coisa está ocorrendo !
Pelos relatos vejo muitos problemas semelhantes em várias máquinas.
Será que teremos novas atualizações que corrijam ela ?

Vladimir-Mihai Pacuraru 10 Reputation points2026-11-12T10:01:52.9233333+00:00 Hello everyone!
I’m having the same issue.
(KB5132061) (26300.9974) Installation error - 0x800f081f
I’ve already tried downloading it for both version 25H2 and 26H2. I followed the steps to clear the Temp, %Temp%, Prefetch, and Recent folders, and I also deleted the SoftwareDistribution folder—yet the same error persists: it downloads, but it won’t install. I even tried using the Update Catalog, but the result is exactly the same!
Judging by other reports, it seems many people are experiencing similar issues across various machines.
Do you think there will be any future updates to fix this?
