Windows updates are supposed to make your life easier. Secure. Fast. But then you hit a brick wall. You see that spinning wheel, the percentage gets stuck at 94%, and then—boom. An error code you’ve never seen before. Honestly, if Windows 11 update KB5058405 fails on your machine, you aren't alone. It’s been a headache for a lot of people lately.
Microsoft pushes these monthly cumulative updates to patch security holes, but sometimes the "patch" feels more like a puncture.
The KB5058405 update is a big one. It’s packed with kernel-level security fixes and some under-the-hood tweaks for the Windows Subsystem for Linux. But for a specific subset of users, it just won't stick. You might see error codes like 0x800f0922, 0x800f081f, or the classic "Undoing changes made to your computer." It's frustrating. It's time-consuming.
Let's talk about why this is happening.
The Real Reasons Your PC Hates KB5058405
Software is messy. Most people think an update fails because their internet blipped. Sometimes that’s true. But usually, it’s deeper. Windows 11 is picky about system files. If you’ve used a "debloater" script to remove telemetry or pre-installed apps, you might have inadvertently broken the servicing stack. When KB5058405 tries to find a file that isn't there, it panics and rolls back.
Another culprit? Disk space. No, not just "I have 10GB left." Windows needs a specific chunk of the System Reserved Partition to be clear. If that partition is stuffed with old boot logs or third-party antivirus metadata, the update fails instantly.
Driver conflicts are also rampant here. If you’re running older hardware or specialized peripherals—think high-end audio interfaces or legacy RAID controllers—the new security protocols in KB5058405 might be flagging the driver as a risk. It blocks the update to prevent a Blue Screen of Death (BSOD), which is technically a "safety feature," even if it feels like a bug.
Sifting Through the Error Codes
You need to know what you're looking at. If you see 0x800f0922, it’s almost always a connection issue with Microsoft’s Update servers or a lack of space in the System Reserved partition. If it’s 0x80070002, Windows can't find the specific files it just downloaded. It’s like a chef losing the ingredients halfway through a recipe.
Basically, your computer is confused.
How to Get KB5058405 Installed Without Losing Your Mind
First, do the easy stuff. Turn off your VPN. I know, it sounds basic, but Windows Update frequently flags non-standard IP ranges as suspicious. If you’re routing through a server in Switzerland while trying to pull a regional update, the handshake might fail.
Now, let's get into the weeds.
Resetting the Windows Update Components
Sometimes the "SoftwareDistribution" folder gets corrupted. Think of this folder as the waiting room for updates. If the waiting room is full of garbage, nobody gets in. You have to clear it out manually. You’ll need to open Command Prompt as an Administrator and stop the services first.
Type net stop wuauserv and hit enter. Then net stop bits.
Once they’re dead, navigate to C:\Windows\SoftwareDistribution and delete everything inside. Don't worry, Windows will recreate what it needs. Restart the services with net start wuauserv and net start bits. Try the update again. This fixes about 60% of these "failed" scenarios.
The SFC and DISM One-Two Punch
If the update still fails, your system image might be the problem. Windows has built-in doctors for this. Open your terminal again.
Run sfc /scannow.
Wait. It might take ten minutes. It might take thirty. If it says it found corrupt files and fixed them, restart and try KB5058405 again. If it didn't find anything, you need the heavy hitter: DISM.
DISM /Online /Cleanup-Image /RestoreHealth
This command actually goes out to Microsoft's servers and pulls fresh copies of system files to replace any "dirty" ones on your drive. It’s the closest thing to a factory reset without actually losing your cat photos.
The Manual Route: Using the Microsoft Update Catalog
Sometimes the automatic delivery system is just broken. It happens. If Windows 11 update KB5058405 fails through the Settings app, you can go around the back door.
Go to the Microsoft Update Catalog. Search for "KB5058405." You’ll see a list. Make sure you pick the one that matches your system (usually x64 for most modern PCs). Download the .msu file.
Double-click it. This bypasses the Windows Update service's logic and forces the installer to run. Often, this "brute force" method works because it isn't relying on the same cached files that the Settings app is tripping over.
What if it Still Won't Budge?
If you've done the DISM repair, cleared the cache, and tried the manual installer, and it still fails? You probably have a third-party antivirus interfering. Programs like Norton, McAfee, or even some versions of Malwarebytes can be overprotective. They see the update modifying kernel files and they stop it. Disable them temporarily—just for the duration of the update.

Also, check your BIOS/UEFI. Windows 11 is very sensitive to Secure Boot and TPM 2.0. If your BIOS is severely outdated, it might not support the specific security handshakes required by this latest cumulative update. A quick firmware flash might be the "missing link" you’re looking for.
Is KB5058405 Even Worth the Trouble?
Look, people ask this all the time. "Can I just skip it?"
Technically, yes. You can pause updates for 7 days, or even 35 days. But KB5058405 isn't just a "pretty icons" update. It addresses several documented vulnerabilities that hackers use for privilege escalation. If you’re using your PC for banking, work, or anything sensitive, you really do want this installed.
That said, if it's causing your specific PC to crash or boot-loop, waiting for the "fix for the fix" is a valid strategy. Microsoft usually acknowledges these "failed to install" loops within a week or two and releases a revised version of the KB or a standalone troubleshooter.
Why You Might Want to Wait
A few users on forums like Reddit and ElevenForum have reported that after force-installing KB5058405, their taskbar flickers or their Wi-Fi speeds drop. These are edge cases. Most of the time, the failure to install is a local configuration issue, not a bug in the update code itself. But if your machine is your livelihood, maybe give it a week to see if a "V2" of the update drops.
Actionable Steps to Take Right Now
If you're staring at that "Failed" message right now, here is exactly what you should do, in order:
- Check your clock. Seriously. If your system time is off by even a few minutes, the security certificates for the update will fail. Sync your time in Settings.
- Run the Windows Update Troubleshooter. It’s in Settings > System > Troubleshoot > Other troubleshooters. It's not perfect, but it catches simple registry hiccups.
- Free up 20GB of space. Even if the update is only 500MB, Windows needs a lot of "scratch space" to move files around during the installation.
- Use the "Media Creation Tool" trick. If all else fails, download the Windows 11 Media Creation Tool from Microsoft. Choose "Upgrade this PC now" and keep your files. This performs an "in-place upgrade," which essentially installs the latest version of Windows (including KB5058405) over your current one without deleting your apps. It’s the nuclear option, but it works every single time.
Keep an eye on the Windows Release Health dashboard. Microsoft keeps a running tally of known issues there. If "KB5058405 fails to install" becomes a widespread, confirmed bug, they will post a specific workaround there that might involve a specific registry key change.
Don't panic. A failed update isn't a dead computer. It's just Windows being Windows. Clear the cache, check your disk health, and if you have to, just force-feed it the manual file. You'll be back to work (or gaming) in no time.
Stop the update service, purge the SoftwareDistribution folder, and try a manual install from the Catalog for the highest chance of success.
