Whatever the cause, we’ve compiled a list of proven methods to help you resolve this error.
1. Run the Windows Update Troubleshooter
Sometimes, Windows updates fail because of system issues that prevent critical security patches from being installed. The Windows Update Troubleshooter is a built-in tool designed to identify and automatically resolve problems related to Windows updates. By running this tool, you can detect and fix issues causing the error. It works by resetting update components, clearing corrupted caches, and installing missing or failed updates.
2. Use Windows Update Assistant
Windows Update may sometimes fail to install critical patches due to corrupted system files, misconfigured update services, or background conflicts. In such cases, the Windows Update Assistant provides a reliable alternative by bypassing the standard update process and directly fetching the latest security patches from Microsoft’s servers. Unlike the built-in updater, it operates independently, avoids relying on potentially corrupted local update cache, and ensures updates are installed even if system components are broken.
3. Use the Media Creation Tool for Updates
If Windows Update keeps failing repeatedly, the Media Creation Tool can be a lifesaver. Instead of troubleshooting corrupted system files or misconfigured settings manually, this tool downloads the latest Windows version directly from Microsoft and performs a clean reinstall without wiping your files or apps (a repair install). Think of it as refreshing Windows itself—it replaces outdated or missing security updates that may be causing the error.
4. Disable Virtualization-Based Security (VBS)
Virtualization-Based Security (VBS) is a Windows feature designed to enhance system security by isolating critical processes using hardware virtualization. While this adds protection against malware, it can block applications like FACEIT Anti-Cheat that require direct access to system resources. The FACEIT Install Assistant relies on accessing specific system services, drivers, and files to verify and install updates. If VBS restricts this access (common in Windows 10/11), the anti-cheat system may fail to validate security updates, triggering the “Your system is missing important Windows security updates” error. Disabling VBS resolves this conflict by removing virtualization-based restrictions, allowing FACEIT Anti-Cheat to function correctly. If none of the solutions above resolve the issue, contact FACEIT Official Support. This will help identify whether the problem stems from their anti-cheat system or a Windows-specific configuration.
