Why does my Windows 11 update show 'Failed' in Update history?

The Failed status in Update history means the update downloaded but could not complete installation. Common causes are corrupted system files in the Windows component store, a driver that conflicts with the new update, or insufficient disk space on the C: drive. The fix steps above — DISM, SFC, and driver checks — resolve the majority of these failures.

How do I find the error code for a failed Windows 11 update?

Go to Settings > Windows Update > Update history. Click on the failed update entry to expand it — the error code appears as a hex value like 0x800f0922 or 0xc1900101. You can also view detailed logs at C:\Windows\WindowsUpdate.log or use the Event Viewer: open Event Viewer > Windows Logs > System and filter for sources named WindowsUpdateClient.

Is it safe to delete files from the SoftwareDistribution folder?

Yes — it is safe to delete the contents of C:\Windows\SoftwareDistribution\Download after stopping the Windows Update service with net stop wuauserv. Do not delete the folder itself, only its contents. Windows automatically re-downloads update packages on the next update check. Your installed programs, files, and Windows settings are not affected.

How long does DISM /RestoreHealth take on Windows 11?

DISM /Online /Cleanup-Image /RestoreHealth typically takes between 10 and 30 minutes depending on internet speed and how much of the Windows component store needs repair. The progress counter may appear to stall at certain percentages — this is normal. Do not close the Command Prompt window while DISM is running.

Can I use Windows Update when antivirus is running?

Usually yes, but some antivirus products interfere with Windows Update by blocking file writes to the SoftwareDistribution folder or scanning update packages during installation, which can cause failures. If updates fail only when your antivirus is active, temporarily disable real-time protection before running Windows Update. Re-enable it immediately after the update installs.

Windows 11 Update Failed — Fix

Windows 11 update failed means a cumulative update, security patch, or driver update downloaded successfully but could not complete installation — Windows Update shows a “Failed” status in Update history. According to Microsoft’s official troubleshooting documentation, the most common causes are a corrupted Windows component store, driver conflicts that interrupt installation, and a corrupted SoftwareDistribution download cache.

Windows 11 update failed — fix steps: troubleshooter, clear cache, DISM and SFC, driver check, manual install from Update Catalog

What causes Windows 11 updates to fail

Windows 11 update failures at the installation stage — as opposed to the download stage — typically come from one of these sources:

Corrupted Windows component store — the WinSxS directory that updates modify has damaged entries, preventing the new files from being applied correctly
Driver conflict — a hardware driver cannot initialize in the updated Windows environment, triggering an automatic rollback
Corrupted SoftwareDistribution cache — partially downloaded or corrupted package files that Windows attempts to install from
Insufficient disk space — cumulative updates require 3–5 GB free; the installation fails silently if space runs out mid-install
Corrupted system files — individual system files that the update needs to replace are locked or already damaged

How to fix Windows 11 update failed

Step 1 — Run the Windows Update Troubleshooter

The Windows Update Troubleshooter is Microsoft’s first-line diagnostic tool. It checks the Windows Update service (wuauserv), Background Intelligent Transfer Service (BITS), and update metadata integrity, and applies automatic repairs.

Go to Settings → System → Troubleshoot → Other troubleshooters
Click Run next to Windows Update
Follow any prompts and apply suggested fixes
Restart your PC when the troubleshooter completes
Go to Settings → Windows Update → Check for updates and retry

This step alone resolves failures caused by stopped services or misconfigured service settings.

Step 2 — Clear the SoftwareDistribution folder

Windows Update downloads update packages to C:\Windows\SoftwareDistribution\Download. If any package file is corrupted — from a previous failed download or a power interruption — Windows retries from the corrupted file and fails again. Deleting the contents forces a clean re-download.

Right-click Start → Terminal (Admin) or Command Prompt (Admin)
Stop the update services:

net stop wuauserv
net stop bits

Open File Explorer and navigate to C:\Windows\SoftwareDistribution\Download
Select all contents (Ctrl+A) and delete — leave the Download folder itself in place
Return to Command Prompt and restart the services:

net start wuauserv
net start bits

Go to Settings → Windows Update → Check for updates

Windows re-downloads the failed update package from scratch. The first check may take a few minutes longer than usual.

Step 3 — Run DISM then SFC to repair system files

If clearing the cache did not resolve the failure, the Windows component store — the repository that updates modify — may be corrupted. DISM repairs it by downloading replacement components directly from Windows Update.

Open Command Prompt as administrator and run:

DISM /Online /Cleanup-Image /RestoreHealth

This contacts Windows Update servers to download and replace damaged component store files. It takes 10–30 minutes. Do not close the window.

After DISM completes, run SFC to repair individual system files:

sfc /scannow

SFC uses the repaired component store as its source. When it finishes, restart your PC, then go to Settings → Windows Update → Check for updates and retry the failed update.

Step 4 — Check driver compatibility in Device Manager

Driver conflicts are a leading cause of update installation rollback — the update begins applying, a driver fails to initialize in the new environment, and Windows rolls back automatically.

Right-click Start → Device Manager
Look for any device with a yellow warning triangle — this indicates a problem
Right-click the flagged device → Update driver → Search automatically for drivers
If no automatic update is found, visit the manufacturer’s website and download the latest driver manually
Also check for recently updated drivers: right-click a device → Properties → Driver tab → use Roll Back Driver if a recent update is listed

After updating or rolling back drivers, restart your PC and retry the Windows update.

Step 5 — Install the update manually from Microsoft Update Catalog

If Windows Update continues failing for a specific update, download and install it directly from Microsoft’s Update Catalog — this bypasses the Windows Update delivery mechanism entirely.

Go to Settings → Windows Update → Update history
Note the KB number of the failed update (for example, KB5034123)
Open a browser and go to catalog.update.microsoft.com
Search for the KB number and download the version matching your Windows edition and processor (x64 for most PCs)
Run the downloaded .msu file as administrator
Follow the installation prompts and restart when prompted
Go to Settings → Windows Update → Update history and confirm the status shows Successfully installed

How to verify the fix

Go to Settings → Windows Update → Update history after the update installs. The entry for the previously failed update should show Successfully installed with today’s date. If Windows Update now shows “You’re up to date,” the issue is resolved.

If updates continue failing with the same error code, check the specific guide for that code: error 0xc1900101 (driver rollback) or the Windows 11 Upgrade Errors hub for additional guides.
