How to Fix KB5022845 or KB5022497 Update Not Installing on Windows 11

Is your Windows 11 computer having trouble installing the KB5022845 or KB5022497 updates? These are important updates that patch security vulnerabilities in the Windows operating system and the .NET Framework, so it‘s crucial to get them installed to keep your system protected. In this comprehensive guide, we‘ll walk you through multiple methods to troubleshoot and resolve issues preventing these updates from downloading or installing successfully.

The KB5022845 cumulative update for Windows 11 includes security fixes for core Windows components and functions. It patches vulnerabilities that could allow an attacker to gain elevated permissions on your system. This update is rated Critical, Microsoft‘s highest severity rating, so it‘s very important to install.

The KB5022497 cumulative update focuses on the .NET Framework, a development platform used by many applications. Specifically, it fixes reliability issues in .NET Framework 3.5 and 4.8.1 on Windows 11. It also patches a vulnerability in the MSDIA SDK and the Visual Studio WMI Setup Provider Installer. Applications that rely on these components could experience crashes or failures until this update is installed.

Windows Update should automatically download and install these updates, but sometimes the process can hit a snag. If you see an error message when trying to install KB5022845 or KB5022497, or your computer seems stuck downloading the update, try the fixes below to get things moving again.

Fix 1: Run the Windows Update Troubleshooter
The first step to try is Windows‘ built-in troubleshooter for identifying and resolving common issues with Windows Update. Here‘s how to run it:

  1. Open the Start menu and click Settings.
  2. Click System, then Troubleshoot in the left sidebar.
  3. Click Other troubleshooters.
  4. Next to "Windows Update," click the Run button.
  5. The troubleshooter will scan for issues and automatically apply any identified fixes.
  6. Restart your PC and try installing the updates again.

The troubleshooter can detect problems like missing or corrupted files, incorrect settings, and service issues that may interfere with Windows Update. However, some more complex issues require different solutions, so continue to the next fixes if the troubleshooter doesn‘t resolve the problem.

Fix 2: Restart Key Services
If a Windows service used by the update process gets stuck or shut down prematurely, it can prevent updates from downloading or installing. Restarting a couple key services can resolve issues like error 0x80070424 or 0x800f0922.

  1. In the Start menu, search for "Services" and open the Services app.
  2. Scroll down to "Windows Update" service. Double-click to open its properties.
  3. Change the Startup type to Automatic, then click Apply and OK. If the service is not running, click Start to start it.
  4. Additionally, scroll down to "Background Intelligent Transfer Service." Double-click to open it.
  5. Change its Startup type to Automatic, then click Apply and OK, and Start the service if not running.
  6. Restart your PC and attempt the updates again.

The Windows Update service is the core component for downloading and installing updates. The Background Intelligent Transfer Service handles scheduling and optimizing these downloads. Ensuring both are running and set to start automatically can fix some of the most common update issues.

Fix 3: Use the Windows 11 Installation Assistant
Microsoft provides a special tool for installing feature updates and upgrading to the latest version of Windows 11. Using it to install the current version of Windows 11 should automatically include the latest cumulative updates like KB5022845 and KB5022497. Here‘s how:

  1. Visit the Windows 11 download page: https://www.microsoft.com/en-us/software-download/windows11
  2. Click the "Download Now" button under Windows 11 Installation Assistant.
  3. Open the downloaded file and click Accept and Install to begin the update process.
  4. The installer will automatically fetch and install the latest version of Windows 11 along with available cumulative updates.

The Installation Assistant is a full in-place upgrade of your Windows 11 installation that shouldn‘t affect your files or applications. However, be sure to backup any critical data first before proceeding, just in case anything goes wrong during the process.

Fix 4: Download and Manually Install via Update Catalog
If Windows Update is failing to fetch the KB5022845 or KB5022497 files, you can download them directly from Microsoft‘s Update Catalog site instead. Follow these steps:

  1. Go to https://www.catalog.update.microsoft.com/
  2. Search for "KB5022845" or "KB5022497"
  3. Locate the correct download for your system – it should specify Windows 11 and match your system architecture (x64 or ARM64).
  4. Download the update file, then double-click it to begin the manual installation process.
  5. Restart your PC when prompted to complete installation.

Be very careful to only download the update files directly from Microsoft‘s official Update Catalog. Do not download Windows Updates from any third-party sites, as they may contain malware or be modified.

Fix 5: Reset Windows Update Components
If the previous fixes haven‘t helped, the underlying Windows Update components themselves may be corrupted. Resetting them to their original state can clear up odd issues:

  1. Open Notepad
  2. Copy and paste the following commands:
  net stop wuauserv  
  net stop cryptSvc
  net stop bits
  net stop msiserver
  ren C:\Windows\SoftwareDistribution SoftwareDistribution.old 
  ren C:\Windows\System32\catroot2 catroot2.old
  net start wuauserv
  net start cryptSvc
  net start bits
  net start msiserver
  1. Click File -> Save As…
  2. Set "Save as type" to "All Files"
  3. Name the file "WUReset.bat" and save it to your desktop.
  4. Right-click the WUReset.bat file and choose "Run as administrator"
  5. Restart your PC once the script finishes.

This script will completely clear out the Windows Update caches and databases, then restore the associated services to their default state. This will trigger Windows Update to rebuild its update catalog and file repository from scratch, which can clear up strange corruption issues.

Fix 6: Perform a Repair Upgrade
If all else fails, performing a full "repair upgrade" of Windows 11 should restore Windows Update functionality while preserving your apps and files. You‘ll need a Windows 11 ISO file for this method:

  1. Go to https://www.microsoft.com/en-us/software-download/windows11
  2. Under "Create Windows 11 Installation Media", click Download Now.
  3. Open the downloaded file and select "Create installation media for another PC"
  4. Choose "ISO file" then select a location to save it.
  5. Once the ISO is created, open File Explorer and mount it (right-click -> Mount)
  6. Browse to the mounted drive, then run Setup.exe
  7. Select "Keep personal files and apps" when prompted.
  8. Follow the rest of the prompts to perform the repair upgrade.

This method essentially performs a clean install of Windows 11 overtop your existing installation. Your files, apps, and settings should remain intact, but the core Windows files will be replaced. This usually clears up Windows Update issues while avoiding a full system wipe and reinstall.
