Microsoft Confirms Windows 11 Bug That Locks Users Out of the C: Drive - Reddthat

>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.

Never again, Windows.
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.
Or worse: AI is doing the QA as well
What QA? Microsoft’s QA was always the CEO demoing the latest repository head on stage.
They at least used to be embarassed by a live BSOD.
We’re doing the QA.
“Code Testing” = QA
It passed the unit test, it must be good!
Quality Artificial Intelligence assurance
They don’t need testing because they tell the ai to not make any errors
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%

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.

That’s about 90% of what I use AI for right there: silly little bash and python scripts. A graph, some image compression, ffmpeg video shenanigans, the works.
It’s really really bad at doing spreadsheet analysis. Even basic shit that I would give to an intern. At least an intern with generally just make shit up and pretend it’s not wrong even when I point it out, and if they do I get a new intern.
It’s Microslop. This is what’s wrong.

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.

Seriously?!?! 😲
No, but are we gonna wait until they do?
No one smart is going into windows dev in 2026. It’s like working on IBM mainframes. Only people left to work are middle of the road new grads they hire and boomers who are retiring.

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.

Probably AI code getting tested by AI.
Vibecoding. Microslop has peddled AI so much that they have gotten addicted to their own supply.
They need to rapidly reduce the complexity of their software if they want to get this under control. The answer is NOT to add more features, it’s to simplify things.
Great idea, I’ll ask Copilot to do that
They aren’t capable of doing that.
Why use their stock ticker instead of their name?
Force of habit, shorter to type, everyone knows what I mean.
That was the state of windows in 2005
We just had this month’s Patch Tuesday and they’re still dealing with problems caused by last month’s?! I really need to try harder to convince my father putting Linux on his current computer is a better idea than buying a Windows 11 computer.

Can you still use the computer? Other than the home folder (or the user folder), I think it’s fine if regular users go a week without touching their C drive until Microslop fixes it (which they will, inside like a week).

I use Windows at work, and it’s fine. I do use the home/user folder just because it’s there and it’s how everything’s set up, but there is no other drive to use instead. If I were using it at home, especially if I had a laptop, I’d want the home drive to be on an SSD I could move between machines… maybe. But, I use Macs at home.

I…. I can’t believe you are defending (or more accurately saying “it’s not that bad”) losing access to the root of your hard drive. It screams incompetence on Miroslop’s part.
And it screams incompetence on his part if he actually thinks this isn’t a problem.
Well I’m obviously not, I’m just saying, if the system wouldn’t boot at all, they’d lead with that. For most users, it won’t matter. For the more technical users, we’re either using Linux or macOS.
i put my computer stuff on the part of the computer where the stuff goes, losing access to the stuff on the computer would be a problem yes

from the article

The issue appears mainly on Samsung laptops and can prevent users from accessing files or launching applications.

Having a computer that cannot launch applications, let alone access files, is basically the same as not having a working computer.

But it can boot into Windows, which is also on the C drive? So it’s not locking users out of the C drive, it’s locking users out of parts of the C drive.
The boot process isn’t an user process, Windows would still be able to use the C:/ drive for itself, for every other user software though, that’s another story…
So only the user process is locked out of the C drive, not the boot/system. Fortunately, the way Windows 10/11 works by default, if you sign into a Microslop account, it backs all that stuff up to OneDrive. At least your documents. And no one’s saying it’s not bad, it just seems like most affected individuals will be able to go about most of their day. I have a Mac, so I don’t need to worry about any of this have separate issues to worry about.
Having OneDrive wouldn’t help as you still won’t be able to use programs as a user, which is pretty much the reason we use computers in the first place, this bug effectively makes whole computers glorified paperweight in the meantime.

Hardly.

The system drive (very usually C:/) is where the Users folder lies by default (and you can’t move it anyway IIRC), folder that contains stuff like the Appdata folder where… well… apps keeps their data like settings, history, backups… Most software will try to access it and would meet an “access denied” error.

This is also the default location for all the documents, music, videos, pictures,[…] folders (but you can change those though)

Basicaly you’d be limited to the “portable” versions of softwares located on other drives, which is not quite the norm on Windows.

Hopefully this doesn’t give Microslop executives the idea of turning it into a feature to force their users to save their files onto OneDrive
Let’s not pretend that Linux is without bugs.
Let’s not pretend that Microslop is capable of producing good software.
I don’t know about that, XP, 2000 and 7 was pretty solid.
Not gonna mention Windows 8? Hmm I wonder why…
Or vista lol, or windows 98 that was so bad they essentially recalled it and re-released it as a second version?

Everyone forgets MILENNIUM!

Because of the trauma.

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.

Because it was shit.

I never claimed that everything MS did was good

Fair point.
XP was probably their most solid OS. And that shouldn’t be a brag.

Reputation is such a strange phenomenon. XP was considered a disaster at launch. It took them years to repair everything that didn’t work.

The rollout of 64 bit architecture support was so sloppy that people were holding on to old hardware so as to not have to install the x64 version of XP. The premiere of the NT kernel meant that nothing had drivers, most software wasn’t compatible yet. DirectX 9 broke half of old games compatibility. There were also two entirely different versions of the shell with dramatically different start menus. Some versions didn’t support multi core CPUs.

It wasn’t until the end life of XP and the launch of Vista that people started to cling to XP and its reputation switched due to a mix of nostalgia and fear of the much worse launch of Vista.

I think .net is pretty good. People love VS Code.
