Windows users, buckle up—there’s an interesting development in the world of Windows 11. Microsoft recently confirmed some frustrating installation issues that are causing headaches for a small subset of users running Windows 11 24H2. If you’ve dabbled in creating customized Windows installation media or integrated newer updates into your ISOs, you might find yourself trapped in an awkward predicament where future cumulative updates simply refuse to install. Let’s break it down and figure out what’s happening, why it’s happening, and what you can do about it.
What do you think about this update fiasco? Have you run into similar issues with Windows ISOs or cumulative update conflicts before? Let us know in the forums!

What’s the Deal With Windows 11 24H2?
Let’s start with the good news: Windows 11 24H2 has been praised as one of the stablest iterations of Windows 11 to date. It builds upon the groundwork laid by its predecessors, offering improved performance, polished features, and fewer bugs—at least for most users. But for those who’ve taken matters into their own hands and created customized installation media to include October and November 2024 cumulative updates, the process might have introduced a pesky bug.The Problem
Specifically, if you installed Windows 11 24H2 using an ISO that already includes the October or November 2024 security updates—whether you made this ISO with tools like Rufus, DISM (Deployment Image Servicing and Management), or other third-party software—there’s a chance that your system can no longer accept further updates via Windows Update. This means:- December updates and beyond fail to install.
- Your system is essentially locked into the state it was in at the time of that custom installation.
Why Did This Happen?
To fully grasp the “why,” it’s important to understand how Windows Update operates:- Update Catalog Coordination: Windows Update has a very particular way of managing patches, security updates, and cumulative changes. When you sidestep this process by pre-integrating updates, you’re introducing modifications that Windows itself didn’t account for.
- Custom ISOs vs Microsoft’s Tools: Microsoft’s methods for deploying updates are designed to be modular and sequential. Uploading a custom ISO with pre-baked updates essentially disrupts the natural chain of cumulative patching, which means the system doesn’t “recognize” the December update as part of the sequence.
- No Official Pre-Patched ISOs Available: This could’ve been avoided if Microsoft had periodically released ISOs that included all cumulative updates up to the current month, but they don’t do this. If you want an updated ISO, you either need to use the base image and run updates manually after installation or risk using custom methods that might backfire—like in this case.
Affected Users: A Small But Stuck Group
While this problem has sparked some discussion online, the silver lining here is that the issue seems limited to a small number of PCs. After all, most users either:- Download Windows 11 fresh from Microsoft’s official Media Creation Tool,
- Update directly through Windows Update after a clean installation, or
- Use Microsoft Update Catalog to grab patches manually.
What Can You Do About It?
If you’re one of the affected users, there’s currently no magical one-click fix. Microsoft has recommended a workaround, but—be warned—it’s a time-consuming one.Step 1: Reinstall Windows 11 24H2 with a Fresh ISO
The only guaranteed way to restore update functionality is to reinstall Windows 11 24H2 using an official, unmodified ISO. Here’s how to do it:- Download the Media Creation Tool from Microsoft.
- Head to Microsoft’s website and grab the tool for creating a bootable USB drive or ISO.
- Create a Fresh Installation Media.
- Use the Media Creation Tool to prepare a USB drive or ISO without tinkering with it or injecting any updates.
- Reinstall Windows.
- Backup all important data before proceeding to reinstall the operating system. This is, unfortunately, a full reset of your installation.
Step 2: Apply Updates Normally
Once you’ve reinstalled Windows 11 using the base ISO, use the built-in Windows Update feature to download October, November, December (and subsequent) updates sequentially in the way Microsoft intended. This ensures there are no conflicts with the update mechanism.What About a Direct Fix or Workaround?
Here’s the kicker: there isn’t one yet. Microsoft has confirmed that they’re aware of the issue and are working on it. The company expects to provide a more permanent solution in January 2025 after their engineering team returns from the holidays. However, for those already struggling, waiting until January for a fix is... less than ideal.Why It’s Worth Waiting for the Fix
Before you drop everything and reinstall your OS, remember that this issue doesn’t affect system performance or day-to-day use. If waiting for a proper fix from Microsoft doesn’t inconvenience you, it might be worth holding off on drastic measures. Here’s why:- Microsoft typically resolves serious bugs quickly, especially when they impact the update mechanism itself.
- A patched update in January could potentially restore your system’s ability to receive cumulative updates without the need for a full reinstall.
Lessons Learned: Don’t Tinker Without a Cause
For those who enjoy experimenting with custom ISOs, this issue serves as a reminder: modifying installation media comes with risks, and sometimes even the smallest tweak can lead to unexpectedly big problems. In hindsight, it’s clear that sidestepping Microsoft’s processes in this way wasn’t worth the trouble—you ultimately end up with more work on your hands than if you’d just let things unfold organically.Wrapping It Up
Windows 11 24H2 continues to shine as a reliable and feature-packed update for most users, but this installation bug highlights how technical decisions—like integrating updates into ISOs—can disrupt even the smoothest systems. Whether you’re holding out for Microsoft’s fix in January or biting the bullet and reinstalling the OS now, the key takeaway is this: follow the official software processes where possible. It’ll save you a lot of headaches in the long run.What do you think about this update fiasco? Have you run into similar issues with Windows ISOs or cumulative update conflicts before?
