Error with recent windows security update: 2026-05 Security Update (KB5089549) (26200.8457) Error Code: (0x80073712)

Dylanger Shots 40

I am unable to install the May 2026 Security Update (KB5089549) for Windows 11 Home (Version 24H2/25H2, Build 26200.8457). The update consistently downloads but fails during installation at 11%, rolling back with Error Code: 0x80073712.

I have attempted the following repair steps without any success:

DISM Repair with ISO Source: Ran DISM /Online /Cleanup-Image /RestoreHealth /Source:wim:[ISO_Drive]:\sources\install.wim:1 /LimitAccess using a mounted Windows 11 ISO matching my exact edition (Home, Index 1). The operation reported success.
System File Checker: Immediately followed up with sfc /scannow, which verified 100% integrity with no violations found.
Windows Update Component Reset: Stopped BITS/Wuauserv services and manually deleted the C:\Windows\SoftwareDistribution and C:\Windows\System32\catroot2 folders to clear the update cache.
Antivirus Interference: Temporarily disabled third-party security software and Windows Defender real-time protection during installation attempts.

Any help will be greatly appreciated!

Hello Dylanger Shots,

Thanks for circling back with the fix. It's really useful that you laid out what didn't work too.

The reason the Update Catalog route worked is that 0x80073712 usually means a piece of the servicing/component store is missing or out of sync, and Windows Update keeps tripping on it. Grabbing the standalone .msu and running it directly sidesteps that whole pipeline and just applies the package — which is also why a second run can push it through after the first one looks like it failed.

I appreciate you sharing the resolution and the direct link — this is a clean, repeatable fix, and it'll save the next person hitting 0x80073712 on KB5089549 a lot of the same dead ends you already ruled out.

Hey so I tried installing it 3 times and still it says installation failed. Not sure why the update process is so broken for me but is there any reason/fix for my issue?

Hi Ivy W,

The exact error code matters here. Worth checking it under Settings > Windows Update > Update history, on the failed KB5089549 entry.

If you're getting the same 0x80073712 that OP had, then the fix he shared above is your best bet.

If it's a different code (say it fails around 35% on reboot, or shows something like 0x800f0922), that's likely a separate issue from this thread — I suggest starting your own question with the details so it gets looked at properly rather than getting mixed in here.

Answer 2

UPDATE — RESOLVED

For anyone else hitting this issue, I was able to fix it by manually downloading and installing KB5089549 directly from the Microsoft Update Catalog rather than through Windows Update.

Direct link to the update: https://www.catalog.update.microsoft.com/Search.aspx?q=2026-05%20Security%20Update%20(KB5089549)%20(26200.8457)

Make sure you grab the correct version for your architecture (x64 for most people) and your Windows version (25H2 or 24H2). Run the .msu file, let it complete, and then restart. The update may appear to fail on the first attempt — if so, try running it a second time before restarting.

Hope this helps someone!
