FACEIT, the popular competitive gaming platform, requires specific Windows security updates to function properly with its anti-cheat system. Many users encounter issues when these updates are missing or improperly installed, preventing them from joining matches. This comprehensive guide walks you through troubleshooting and resolving these update-related problems on both Windows 10 and Windows 11 systems.

Why FACEIT Requires Specific Windows Updates

The FACEIT anti-cheat system relies on several critical Windows security components:
- Virtualization-Based Security (VBS): Protects against sophisticated cheating techniques

Without these security features enabled through Windows updates, the anti-cheat system cannot guarantee a fair playing environment.
