⚠️ Why Does KB5058481 Fail to Install?

There are several technical and environmental factors that can prevent KB5058481 from installing successfully:

1. Corrupted System Files

The Component Store (WinSxS) may be corrupted due to abrupt shutdowns, malware, or failed previous updates.

2. Insufficient Disk Space

The update requires at least 1–2 GB of free space on the system drive (especially C:\). Low disk space can cause extraction or installation failure.

3. Outdated or Conflicting Drivers

Old drivers, especially for storage controllers or chipsets, can interfere with the update process.

4. Third-Party Antivirus or Endpoint Protection Tools

Security software sometimes blocks access to system files required by Windows Update.

5. Windows Update Service Issues

Malfunctioning or misconfigured services like Background Intelligent Transfer Service (BITS), Windows Update Agent, or TrustedInstaller can halt the update process.

6. Pending Reboots or Incomplete Previous Updates

If the system has pending reboots or uncommitted changes from prior updates, new patches cannot apply cleanly.

2. Run the following commands in order:

   sfc /scannow

If SFC finds issues:

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

These tools repair the Windows image and ensure the Component Store is healthy.

📋 Solution 3: Free Up Disk Space

Steps:

1. Run Disk Cleanup (cleanmgr) and select Windows Update Cleanup
2. Uninstall unused applications or move data to external storage
3. Ensure at least 2 GB of free space on the system drive

You can also use Storage Sense to remove temporary files and optimize space.

🧪 Solution 4: Reset Windows Update Components

Steps:

1. Open Command Prompt as Administrator
2. Stop essential services:

   net stop wuauserv
   net stop cryptSvc
   net stop bits
   net stop msiserver

3. Rename the SoftwareDistribution and Catroot2 folders:

   ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
   ren C:\Windows\System32\catroot2 catroot2.old

4. Restart the services:

   net start wuauserv
   net start cryptSvc
   net start bits
   net start msiserver

This clears corrupted update caches and resets the update engine.
