KB5077181 was released about a month ago as part of the February Patch Tuesday rollout. When the update first arrived, users reported a wide range of problems, including boot loops, login errors, and installation issues.

Microsoft has now acknowledged another problem linked to the same update. Some affected users see the message “C:\ is not accessible – Access denied” when trying to open the system drive.

  • Who could have possibly predicted that an operating system with vibe code in the kernel would be complete ass

      • Its funny how literally every bug in code now is assumed to be AI, as if we didn’t live/deal with buggy programs for decades before it.

        • 21 hours

          Sure, but it certainly seems like we are seeing a greater number of software errors caused by bad or sloppily implemented features now, compared to before LLMs were readily available and good enough to produce (mostly) passable code. Far too many companies, including Microslop, put too much faith in the technology, and that seems to correlate with many of these problems popping up.

          • Is there any data to back that up? I remember many Microsoft issues throughout the years, pretty bad or dumb bugs frequently.

            • 15 hours

              I have no scientific sources I can point to to back it up. A hunch is what it is, ultimately. It seems true to me, but I suppose I could be wrong. I suspect it’s difficult to really prove this one way or the other.

  • Seems like quite an important drive to have access to. They should probably try to fix that. imo

  • You don’t need C:\. All your data should be in the 365 cloud anyway. Storing files locally in C:\ leads to antipatterns like not paying Microsoft for 365 access (a.k.a “Software Piracy”)

  • There must be something really seriously wrong at Microsoft. I can understand that Windows patches are complex and that they might break some of those crazy things people are running on their machines. But how is a bug that is killing access to the C:\ drive able to get through testing? WTF are they doing?

    • It’s going to come out that there’s AI in the code. And the code testing was done by AI, who gave the buggy code the green light.

      • my boss loves AI and he uses it for everything. he made some stats graphs and summaries, and he was bragging how he got AI to make them errorless: he tells it to check for errors and makes it swear it’s accurate… while we were looking at a graph where the y column numbers were all fucked up

        • Interestingly, AI is actually pretty good at making graphs, the trick is you don’t ask it to actually make the graph itself. Instead you have to ask it to write a python script to create a graph using matplotlib from whatever source file contains the data, then run that script. Same with math. Don’t ask it to do math directly, instead ask it to write a bash or python script to do some math, then run that. Still not perfect, but your success rate increases by about 1000%

          • 3 days

            Because of so much open source and stack overflow it was trained on.

            But who writes bash scripts to do math?

            • But who writes bash scripts to do math?

              A full script? Nobody. But you can just run it interactively on the command line, which a lot of AI clients have access to. bc works great for basic math in the shell.

      • And then the LLM says something like “You’re absolutely right, there was an error in that code that is clear and obvious now it has been pointed out and despite the fact you gave the instruction to make no errors. Is there anything else I can help with?”

        … and they’ll be too blind to take that as the warning it is and continue to ask even more of the LLM.

    • It’s Microslop. This is what’s wrong. Also, that they fired too much of the testing staff in favor of (user-)testing rings.

      It’s not as bad as that time they permanently deleted user documents and photos.

      See they had this trick where if you didn’t have enough space on your drive to unpack an update, they’d just move your shit to OneDrive temporarily, then move it back when the update was done. Only they forgot to move it back, and lost it. Oops.

    • My company is starting to roll out having AI both put up PRs AND give code reviews.

      I would not be surprised to hear Microslop is doing the same thing and having horrible results.

      Amazing what happens when you try to turn your talent pool into lifeless casino monitors.

              • I used 98 as a teen, it came pre installed, what was wrong with it compared to 95? Asking out of curiosity.

                • Man it’s been a long time but essentially 98 was the first one to allow for plug and play without drivers if I’m remembering right. That and a few other stability issues made the original crash constantly, including during the demo at a tech show. They re-released it as a second edition that fixed most of it. If you bought the computer towards 1999 they had fixed it.

        It’s a lot easier to accept bugs when you’re not paying for it, it’s not spying on you, it lets you do what you want, and it respects your freedom.

        It is a hell of a lot less buggy

        And the bugs that are there we are aware of. Microsoft may or may not fix severe security bugs, opting to hide the information instead because it’s better for their bottom line

        Microsoft always had been a bug riddled mess that people paid for and then they needed to pay even more to be able to get their shit still working

        Now with the AI slop apparently contributing 30% of the code, things have gone off a cliff

        So no, nobody is pretending Linux is bug-less, it’s just that Microsoft is that bad

        • Also remember that it’s called C drive because your A and B drives are still floppy drives in 2026

          Yeah, I made my comment as I am tired of fanboyism, I have daily driven Linux in the past, I was the Linux sysadmin at a major financial institution for years, Linux is awesome!

          But please don’t get arrogant and claim it is faultless, with constructive criticism it can only get better.

          Right now I am running Windows as my daily, and my work is only in Windows.

          I dailied Linux back in the 2.8 days, I remember a class mate having to manually edit the kernel source code to get his USB mobile broadband modem to work, I had modems from another brand, so I only had to run USB mode switcher to get mine working.

          I set up Fluxbox from scratch to get a fantastic UI experience on my laptop.

          I know Linux.

          I switched back to Windows for gaming, and now with W11 and gaming support for Linux, I am looking to move back to Linux.

          I am no Windows nor Linux fanboy.

          • It’s not so much Linux fanboyism as it is Windows (whatever the total polar opposite of fanboyism is)

            The only good argument for Windows is specific software compatibility. If there were equivalent solutions on both for everything, it is an absolute truth that Windows is worse.

            That is not an opinion, outside of intentionally wanting to be commercially oppressed.

            Also games access to your kernel just screams to me “I wanna have fun and don’t care about security at all, now gimme my fortnite vbux mom” in the most middle-school voice possible.

              Wow, how quickly people forget…

              Back in 2011, with kernel 2.8.x, gaming on Linux was nothing like it is today, it required dedication, skills and time.

              And at the time I didn’t have the energy to deal with it.

  • Ugh… I’m so tired of “microslop” and “AI slop”.

    I’m not defending Microsoft in any way, but they were releasing buggy updates long before the rise of AI.

    • You know what’s going on inside the large companies that are hoping to cash in on the AI thing? All workers are being pushed to use AI and goals are set that targets x% of all code written be AI-generated.

      And AI agents are deceptively bad at what they do. They are like the djinn: they will grant the word of your request but not the spirit. Eg they love to use helper functions but won’t necessarily reuse helper functions instead of writing new copies each time it needs one.

      Here’s a test that will show that, with all the fancy advancements they’ve made, they are still just advanced text predictors: pick a task and have an AI start that task and then develop it over several prompts, test and debug it (debug via LLM still). Now ask the LLM to analyse the code it just generated. It will have a lot of notes.

      An entity using intelligence would use the same approach to write the code as it does to analyze it. Not so for an LLM, which is just predicting tokens with a giant context window. There is no thought pattern behind it, even when it predicts a “thinking process” before it can act. It just fits your prompt into the best fit out of all the public git depots it was trained on, from commit notes and diffs, bug reports and discussions, stack exchange exchanges, and the like, which I’d argue is all biased towards amateur and beginner programming rather than expert-level. Plus it includes other AI-generated code now.

      So yeah, MS did introduce bugs in the past, even some pretty big ones (it was my original reason for holding back on updates, at least until the enshitification really kicked in), but now they are pushing what is pretty much a subtle bug generator on the whole company so it’s going to get worse, but admitting it has fundamental problems will pop the AI bubble, so instead they keep trying to fix it with bandaids in the hopes that it’ll run out of problems before people decide to stop feeding it money (which still isn’t enough, but at least there is revenue).

      • Now ask the LLM to analyse the code it just generated. It will have a lot of notes.

        Not only will it have a lot of notes, every time you ask if to analyze the code it will find new notes. Real engineers are telling me this is a good code review tool but it can’t even find the same issues reliably. I don’t understand how adding a bunch of non-deterministic tooling is supposed to make my code better.

        • Though on that note, I don’t think having an LLM review your code is useless, but if it’s code that you care about, read the response and think about it to see if you agree. Sometimes it has useful pointers, sometimes it is full of shit.

          • So when do I stop asking the LLM to take another look? If it finds a new issue on the second or third or fourth check am I supposed to just sit here and keep asking it to “pretty please take another look and don’t miss anything this time”?

            I’m not saying it’s a useless tool, it’s just not a replacement for a human code review at all.

            • Stop when you feel like it, just like any other verification method. You don’t really prove that there are no problems with software development, it’s more of a “try to think of any problem you can and do your best to make sure it doesn’t have any of those problems” plus “just run it a lot and fix any problems that come up”.

              An LLM is just another approach to finding potential problems. And it will eventually say everything looks good, though not because everything is good but because that happens in its training data and eventually that will become the best correlated tokens (assuming it doesn’t get stuck flipping between two or more sides of a debated issue).

          • 2 days

            That sounds worse than useless. It would be better to fail utterly than make up shit that you have to waste time parsing through.

            • It helps in the sense of once you’ve looked at code enough times, you can stop really seeing it. So many times I’ve debugged issues where I looked many times at an error that is obvious in hindsight but I just couldn’t see it before that. And that’s in cases where I knew there was an issue somewhere in the code.

              Or for optimization advice, if you have a good idea of how efficiency works, it’s usually not difficult to filter the ideas it gives you into “worthwhile”, “worth investigating”, “probably won’t help anything”, and “will make things worse”.

              It’s like a brainstorming buddy. And just like with your own ideas, you need to evaluate them or at least remember to test to see if it actually does work better than what was there before.

      • You’re spot on regarding how AI operates.

        AI is stupid story time!

        I recently helped a friend with a self-hosted VPN problem. He had been using a free trial of Gemini Pro to try to fix it himself but gave up after THREE HOURS. It never tried to help him diagnose the issue, but instead kept coming up with elaborate fixes with names that suggested they were known issues, like The MTU Traffic Jam, The Packet Collision Quandary, and, my favorite, The Alpine Ridge Controller Trap. Then it would run him through an equally elaborate “fix”. When that didn’t work, it would use the failure conditions to propose a new, very serious sounding pile of bullshit and the process would repeat.

        I fixed it in about fifteen minutes, most of that time spent undoing all the unnecessary static routing, port forwarding, and driver rollbacks it had him do. The solution? He had a typo in the port number in his peer config.

        I can’t deny that LLMs are full of useful knowledge. I read through its output and all of its suggestions absolutely would have quickly and efficiently fixed their accompanying issue, even the thunderbolt/pcie bridging issue, if the real problem had been any of them. They’re just garbage at applying that information.

        • Yeah, they don’t do analysis but can fool people because they can regurgitate someone else’s analysis from their training data.

          If could just be matching a pattern like “I have a network problem with <symptoms>. Your issue is <problem> and you need to <solution>.” Where the problem and solution are related to each other but the problem isn’t related to the symptoms, because the correlation with “network problem” ends up being stronger than the correlation with the description of the symptoms.

          And that specific problem could likely be solved just by adding a description of that process to the training data. But there will be endless different versions of it that won’t be fixed by that bandaid.

  • I like how, once AI is invented, there is never a problem that isn’t AI related.

    Microsoft made broken shit before AI, it isn’t like they suddenly lost that capability once AI was invented.

    • It’s more like the old adage but extended: “To err is human, to really foul things up you need a computer, but to make an unbelievable mess you need an AI.”

      • That seems like an easy statement to prove. How many bugs were there before AI vs after?

        I may be wrong, but I would guess that you haven’t seen any data to back up your statement and you’re basing it on your perception based on social media posts.

        You see a lot of clickbait articles where the author highlights a specific patch note or vulnerability and tries to tie that to AI. They’re doing that to earn revenue because anti-AI posts get traffic… they’re not trying to objectively inform you about the rate of bugs in Microsoft’s products. Your perception is being skewed by selection bias.

            You think I’m basing my perception based on a social media post? That’s very observant.

            You’re right.

            I am responding to a social media post and so my perception of that social media post is based on a social media post (specifically the one that I’m responding to).

            The difference between my comment and their comment is that they present their statement as a fact and I indicate uncertainty.

            I don’t know the person, I may be wrong and they may have the statistics to back up their fact claim. Since I didn’t know for sure I wrote:

            I may be wrong, but I would guess

            This indicates that I am not confident in my answer but it is the current top hypothesis among many.

            I assume (<- see, indicating uncertainty) that they don’t have this data and are simply making it up.

            As far as WHY they are making it up

            Considering that social media is the top news source for most people. (Since this is a fact claim, here is a source: https://www.niemanlab.org/2025/06/for-the-first-time-social-media-overtakes-tv-as-americans-top-news-source/). If you don’t know about a person you have to assume an average person. An average person is more likely to receive their news from social media.

            I don’t think it’s uncontroversial to say that AI is a divisive topic online and so guessing that this person’s perceptions are built on misinformation about AI posted on social media seems to be a pretty rational conclusion based on the facts that I have before me.

                I think maybe you don’t know what ‘weasel words’ mean.

                From Wikipedia:

                In rhetoric, a weasel word, or anonymous authority, is a word or phrase aimed at creating an impression that something specific and meaningful has been said, when in fact only a vague, ambiguous, or irrelevant claim has been communicated. The terms may be considered informal. Examples include the phrases “some people say”, “it is thought”, and “researchers believe”. Using weasel words may allow one to later deny (a.k.a., “weasel out of”) any specific meaning if the statement is challenged, because the statement was never specific in the first place.

                There’s none of that here.

                Summary review:

                The passage does not contain significant weasel words. It acknowledges uncertainty explicitly with phrases like “I may be wrong,” “I would guess,” and “I assume,” which actually counteract weasel wording by qualifying claims. The author distinguishes between fact and opinion, admits lack of knowledge about the individual, and provides a source for a factual claim about social media as a news source. Overall, the language is transparent about uncertainty rather than using vague or evasive phrasing to appear more confident than warranted.

        AI’s use in industry is destructive to knowledge workers, the massive dump of capital in the computer hardware markets have caused massive disruption in secondary markets and the coming market crash will affect everyone in the world. There are plenty of easy arguments to be made against using AI.
