I hate that Microsoft might be vibecoding Windows, but it's inevitable

There's a colloquial saying in my country that goes "in every joke, there's a grain of joke." And the Windows community has been joking and laughing a lot lately. Not from joy, but rather as a coping mechanism caused by the current state of Windows as a platform and Microsoft as a company.

January 2026 has been rough so far, maybe one of the roughest starts to a year in recent history. We receive news of something breaking down daily. It's like an endless lowlight reel of bugs, crashes, server downtimes, and overall instability across all of the company's platforms and services.

The most prominent among the admittedly creative cracks at Microsoft is the one where people accuse it of using AI to generate its own code, or as kids like to say nowadays, vibecoding.

Bashing Microsoft and making memes about “vibecoded Windows” is amusing, as it perfectly blends two things many people aren’t exactly thrilled about: being told AI will replace them and dealing with Microsoft’s recent mishaps. Naturally, that’s the environment where the best comedy happens.

But after the initial laughs, you stop and think about whether the memes could actually be on to something. What if these aren’t just jokes, but an accidental mirror of how Microsoft operates and will continue to operate in the foreseeable future?

Let’s explore.

The Vibe Dunning-Kruger-Effecting

Vibecoding has been sold as the new messiah, a dream machine that can turn non-technical people into software engineers. Anyone who pays a $20 Claude Code subscription to start a million-dollar business, simply by talking plain English to AI.

Twitter (still not calling it X), in particular, is flooded with suspiciously similar posts from all the supposed founders telling you that you’re wasting your life if you’re not making $1m/month with AI right now. All you need is, get this, a Wi-Fi and a MacBook (I guess Windows doesn’t have the same ring to it for developing a SaaS), and you yourself can live the life of your dreams while the software essentially writes itself.

In reality, Claude Code isn’t a millionaire factory. The shininess of AI outputs can easily fool you into believing you’re holding onto something valuable. That is, if you aren’t technical and are amazed by the sheer volume of code on your screen. If you actually are a software engineer, the more you look at the code, the more cracks start to show. It's ironic to see the same people who mock their aunts for interacting with obvious AI slop on Facebook swear by the code generated by the very same tools.

Just like that poor African boy, who’s all alone on his birthday and would greatly appreciate your like, has six fingers and morphs with the sandcastle he’s built on the beach, code written by AI is often riddled with bugs. It's riddled with security issues, crashes frequently, and creates more problems than it solves. Just like... most of the Windows updates lately.

I recently watched a video by How Money Works that explores the broader scale of current AI economics titled “If Not Bubble, Why Bubble Shaped?” And I’m here asking the same question about Windows 11: “If not vibecoded, why vibecode shaped?”

The Clues

First, we need to be clear from the start that there's no way for any of us to tell if anything inside Windows 11 is vibecoded. The OS isn't open source, so nobody outside of Microsoft (possibly not everyone inside, either) can confirm if AI touched any parts of it.

But closed source only stops us from confirming the truth. Enough clues are pointing to some parts of Windows 11 possibly being AI-generated that we'd be naive to dismiss it entirely.

Let’s start with what's almost certainly not vibecoded, and that’s the Windows Kernel. It’s mostly written in C and C++, programming languages in which AI still doesn’t excel. On top of that, I highly doubt Microsoft wants to mess with the most important code in the OS by handing it off to AI.

With the kernel out of the way, we come to our dear friend, possibly the main inspiration for why this debate even exists today, the January 13 Patch Tuesday update (KB5074109). This update caused such havoc for Windows users that it was difficult for me, whose job it is, to keep up with the news, let alone an average user.

KB5074109 was supposed to patch over 100 vulnerabilities and stabilize an already shaken Windows 11. Instead, it triggered a disaster that forced two emergency fixes within two weeks, updates KB5077744 on January 17, and KB5078127 on January 24.

Just take a look at some of the issues that happened in January:

• Outlook Classic became unusable: Many users experienced freezes, hangs, and zombie outlook.exe processes (app appears closed but runs in the background). Unsaved email progress was lost, and users failed to reopen Outlook without killing the process (especially with POP profiles).
• Remote Desktop sign-in failures: Credential prompts failed during connections to Windows 365/Azure Virtual Desktop, preventing sessions from starting.
• Shutdown and hibernate became unreliable: Some PCs restart instead of shutting down or hibernating, or hang entirely during the process.
• Some apps broke down or became unresponsive: Tools like Notepad and Snipping Tool failed to launch, crashed on file operations, or became unresponsive (e.g., error 0x803f8001 tied to app package activation or file handling).

These aren’t kernel-level crashes, but user-facing components where the room for involvement of vibecoding is much bigger. This is the 'safe zone' for experimentation, as potential issues are more likely to result in a frozen window rather than a total system collapse.

And that’s not all. Issues like boot failures due to UNMOUNTABLE_BOOT_VOLUME errors also happened. But these are tightly connected to the kernel, so it’s unlikely they were caused by AI-generated code.

Of course, the counter-argument here is the massive Jenga tower known as ‘technical debt.’ The bugs might just be the result of thirty years of spaghetti code. But that makes the potential involvement of AI even more terrifying. You don't send a chatbot to fix a fragile ecosystem of legacy code and expect it to optimize the codebase without breaking anything.

To be fair, bugs alone don't prove anything. Microsoft, or any other tech company, has shipped broken patches since its inception. Just because something doesn’t work, doesn’t mean it’s automatically vibecoded. However, if we bring the business context into the mix, the clues become harder to ignore.

Satya Nadella admitted Microsoft laid off around 15,000 workers in the first part of 2025 alone, with rumors suggesting the company may cut an additional 22,000 jobs this year. Thousands of experienced engineers who knew Windows inside and out are now gone, and even more will leave in 2026.

These layoffs weren’t caused by financial struggles. Microsoft is currently the 4th most valuable company in the world, worth over $3.5 trillion. The firings happened because the company simply doesn’t need those employees anymore, as the majority of them are now replaced by AI.

Nadella further said that around 30% of Microsoft's code is now being written by AI. Where would that 30% go if not into Windows? Sure, some of it probably ended up in services like Azure cloud, internal tools, and Office suite, but Windows, as a flagship product, is the obvious target for "efficiency gains."

Think about that. Thirty percent of new code, and we're supposed to believe none of it ended up in the January Patch Tuesday that required two emergency fixes?

The Schrodinger’s Links

Here's where it gets interesting. Let's say I'm completely wrong. What if Microsoft doesn't use AI to generate any code for Windows whatsoever, and that 30% of AI-generated code doesn’t end up in shipped products?

That doesn't actually help them.

Microsoft is aggressively pushing AI as the future of productivity. Copilot has been soldered into every corner of Microsoft’s ecosystem, regardless of whether it makes sense for it to be there or not. You can chat with Microsoft’s AI assistant in Paint, Notepad, and even in Photos. In fact, more effort is required to avoid it than to interact with it. Don’t even get me started on the billions invested in OpenAI, datacenters, and the rest of AI infrastructure Microsoft is building.

Now, imagine if, amid all this hype and heavy investments, Microsoft didn’t use AI itself. It would be peak hypocrisy if the company were tenaciously telling users and enterprises to adopt AI workflows while refusing it for its own products.

It would mean they know AI can't handle production code quality, but they're selling it to everyone else anyway. They'd be admitting AI is good enough for your business but not for theirs. Good enough to charge you $30/month for, but not on a level where they would actually trust it with the code that runs on a billion computers.

So, not using AI is out of the question for Microsoft. The company has positioned itself so deeply as AI-first that not using it on Windows would be corporate suicide. They have painted themselves into a corner where they must vibecode to satisfy the narrative, even if they know the quality isn't there yet.

The Bigger Picture

This brings us back to "the aunt test." You can forgive your aunt for falling for AI slop on Facebook. She isn't technologically literate, doesn’t even understand what AI is, and reacts from her soul rather than her logic. But Microsoft is not your aunt. It's a company where the brightest minds on Earth are supposed to work. Expecting them not to fall for the same illusions is reasonable.

If we have established that it is impossible for Microsoft to ditch AI at this point, is it really too much to ask for higher quality control? Or is the company betting that we will accept the broken output because we have no alternative?

But here's a plot twist! I planned to conclude this piece on a pessimistic note, because nothing we knew up until this point gave us any reason for optimism. However, just as I was wrapping it up, I received the news that Microsoft is planning to reevaluate its AI strategy for Windows 11. Apparently, user feedback was getting too hard to ignore.

My first-ever article on Neowin discussed how Satya Nadella said that in order for AI not to be a bubble, it has to provide "genuine value" to users. There, I said that Nadella should listen to his own advice and start making Windows better for the actual users. The latest news hints that he may have started listening.

While there's a glimmer of hope, we still need to see how Microsoft will change its ways with AI in Windows 11. Will this just be a promise to put out a fire, or will we finally see genuine improvement? Because providing genuine value is the only way for the company to stop being Microslop, and start being Microsoft again.
