Latest update won't install

2026-11 Security Update (KB5132061) (26300.9974)

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

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")

That was the first thing I tried but it didn't work. Nothing worked and the "Troubleshooter" was useless as it couldn't identify any issue.

What worked for me was to download the KB5132061 msu file -

https://catalog.sf.dl.delivery.mp.microsoft.com/filestreamingservice/files/5775e69a-9a06-44b1-9b51-4bb89c81f212/public/windows11.0-kb5132061-x64_aedc878e9e078df2ec7e2cfb98dd5b21831cdbcc.msu

Reboot the computer.

Double click on the downloaded msu file to install the update.

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.

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.

I have tried all the suggestions you provided, including the "DISM" method you mentioned last; the situation remains the same for all of us. There are many others experiencing the same issue. Please help.Every time we try—whether via "Windows Update" or by manually downloading the file from Microsoft's own catalog page—it reports that the file is corrupt. Isn't it quite clear that the error lies with Microsoft?

The strange thing is that the "Get Help" option has also stopped working. It just says "Could not be repaired."

Same. The Troubleshooter could "not run the diagnostic". Big help that is.

You can skip installing DISM, all you need repairing it via this command: sfc /scannow
then clear your windows update caches (you can see how do it in answer section (by checking my full detail answer)) if you don't know how to do it.
if you are using windows pro you need to disable your sand box also.
then restart your system and try windows update again, this time you won't stuck at 99%!

Thanks but NONE of that worked. What I did do was a repair install and THAT worked BUT it was not exactly painless as it took quite some time and involved updating previously installed previews, etc. Microsoft needs to more caution when releasing updates; it's not as if this hasn't happened in the past.

Same error here on one of the two Windows 11 I manage: 2026-11 Actualizare de securitate (KB5132061) (26300.9974) Eroare de instalare - 0x80070306 (sorry it's set in Romanian). As soon as I get access to the 2nd one, and if the same error will happen, I'll update my answer!

LE: As I expected, on the 2nd Windows 11, same update: 2026-11 Security Update (KB5132061) (26300.9974) same Install error - 0x80070306! LLE: FWIW (For what it's worth) both systems are Dell Laptops with Windows 11 Professional!

Tried EVERY solution suggested.......EVERY LAST ONE. This MUST be on Microsoft's end because nothing works on one of my Windows 11 machines. It's just a whacked update.

Hi, @Veryold Saint

You're not alone. I experienced the same issue earlier.

While in Settings > Windows Update, please open the Get Help app by following these steps:
1. Scroll down and find "Get help".
2. Click "Get Help" to open the app.
3. Scroll down and look for "Troubleshoot problems with Windows updates".
4. Click it, select "I can't download, install, or uninstall an update", and click "Yes".
If it says "Problem detected", please return to Settings > Windows Update and check whether any download or installation is in progress. Allow it to finish.

If the issue persists, please repeat the steps above.

Click "Add comment" to let me know.

Thanks!

Doesn't work for me. I have two almost identical machines and one got the update without issue and the other will NOT update not matter what, manual download included. Just does NOT work.
