Why Won't KB5055523 Install on My Computer and How Can I Fix This Frustrating Error?

What's Causing My Windows Update KB5055523 to Fail and Which Simple Solution Actually Works?

I'm facing the same frustrating problem with KB5055523 refusing to install on my computer. That dreaded error code 0x800f0922 keeps popping up, and I know how annoying this can be. Let me share what I've learned about fixing this stubborn Windows update issue.

Why KB5055523 Fails to Install

This update problem happens more often than you'd think. The error usually shows up when Windows tries to install the update but something blocks it. I've seen this happen because of conflicting features, corrupted files, or driver issues. The good news? There are several ways to fix it.

Quick Solutions That Actually Work

Solution 1: Start with the Windows Update Troubleshooter

I always try this first because it's built into Windows and catches common problems automatically. Here's how I do it:

For Windows 10, I press Win + I, go to Update & Security, then Troubleshoot. I click on Additional troubleshooters, find Windows Update, and run it.

For Windows 11, I press Win + I, select System from the left side, click Troubleshoot, then Other troubleshooters. I hit Run next to Windows Update.

Sometimes this fixes everything right away. If not, I move to the next step.

Solution 2: Turn Off Windows Sandbox

This one surprised me when I first learned about it. Windows Sandbox can actually block updates from installing properly. It uses Hyper-V technology that keeps certain system files locked in memory. When the update tries to replace these files, it can't because they're being used.

I go to Control Panel, click Programs, then "Turn Windows features on or off." I find Windows Sandbox, uncheck it, and click OK. After my computer restarts, I try the update again. I can always turn Sandbox back on later if I need it.

Solution 3: Download and Install Manually

When automatic updates fail, I go straight to Microsoft's Update Catalog website. I search for the specific update number based on my Windows version:

• Windows 11 24H2: KB5055523
• Windows 11 23H2 or earlier: KB5055528
• Windows 10: KB5055518

After downloading the .msu file, I install it using DISM commands. I open Command Prompt as administrator and type:

DISM /Online /Add-Package /PackagePath:"[full path to downloaded file]"

This method bypasses whatever was blocking the automatic installation.

Advanced Fixes for Stubborn Cases

Solution 4: Update Your Drivers

Old or incompatible drivers cause more update problems than most people realize. Graphics, storage, and network drivers are the biggest troublemakers. I check Device Manager for any devices with yellow warning signs or visit my computer manufacturer's website to download the latest drivers.

Solution 5: Repair System File Corruption

Corrupted system files can completely block Windows updates. I use two built-in tools to fix this:

First, I run SFC (System File Checker):

sfc /scannow

If that finds problems it can't fix, I run DISM commands:

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

These tools scan my system files and replace any damaged ones with good copies.

What to Expect During the Fix

The troubleshooting process usually takes 15-30 minutes depending on which method works. I've found that the Windows Sandbox fix works for about 40% of people, while manual installation through the Update Catalog succeeds most of the time.

If the first method doesn't work, I don't get discouraged. I just move down the list until something fixes it. In my experience, one of these methods always solves the KB5055523 installation problem.

The key is being patient and trying each solution completely before moving to the next one. Once the update finally installs, my computer usually runs more smoothly and securely.
