6 Windows hardening steps that don’t break gaming or DRM

Windows 11 is not the most secure operating system by default but offers ways to enhance security without affecting gaming performance. Gaming PCs are vulnerable to cyber threats and should adopt security measures. Customizing Windows Firewall allows users to maintain internet access for gaming applications while ensuring security. Users should add key game executable files to the "allowed apps" list and consider using SimpleWall for better control over network activity. Using a standard account for gaming sessions enhances security by limiting admin account access, which should be reserved for software installation and updates. Implementing multi-factor authentication for both admin and standard user accounts adds an extra layer of security. Windows Defender has improved and can be an efficient antivirus option, but third-party solutions may conflict with gaming performance. Game files should be added to Windows Defender's exclusion list to avoid performance issues. Disabling unnecessary Windows services can enhance security and performance by reducing the attack surface and freeing up resources. Common services to disable include Cellular Time, Connected Devices Platform Service, and Telemetry. Secure Boot protects against malicious software during the boot process and may require BIOS adjustments. It does not affect gaming performance and is often necessary for games with kernel-level anti-cheat systems. Memory Integrity and Core Isolation are advanced security features that protect against low-level attacks by creating an isolated environment for critical processes. These features require minimal resources if the CPU supports Intel's Mode-Based Execution Control (MBEC) or AMD's Guest Mode Execution Trap (GMET). Balancing security measures with optimal system performance is essential for a secure gaming experience.

Win-DoS Epidemic: New DoS and DDoS Attacks Start with Microsoft Windows

During DEF CON 33, Yair and Shahak Morag from SafeBreach Labs introduced a new category of denial-of-service (DoS) attacks called the “Win-DoS Epidemic.” They identified four significant Windows DoS vulnerabilities, all categorized as “uncontrolled resource consumption,” including: - CVE-2025-26673 (CVSS 7.5): High-severity DoS vulnerability in Windows LDAP. - CVE-2025-32724 (CVSS 7.5): High-severity DoS vulnerability in Windows LSASS. - CVE-2025-49716 (CVSS 7.5): High-severity DoS vulnerability in Windows Netlogon. - CVE-2025-49722 (CVSS 5.7): Medium-severity DoS vulnerability in the Windows print spooler, requiring an authenticated attacker on an adjacent network. These vulnerabilities can incapacitate Windows endpoints and servers, including domain controllers (DCs), which are essential for managing authentication and resources in enterprise networks. The researchers also revealed a new DDoS attack method, termed Win-DDoS, which exploits a flaw in the Windows LDAP client referral process, allowing attackers to redirect DCs to a victim server and continuously repeat this redirection, creating a large-scale DDoS botnet using public DCs without leaving forensic traces.

New ‘Win-DoS’ Zero-Click Vulnerabilities Turns Windows Servers/Endpoints, Domain Controllers Into DDoS Botnet

Researchers Yair and Shahak Morag from SafeBreach Labs introduced a new category of denial-of-service (DoS) attacks called the “Win-DoS Epidemic” at DEF CON 33. They identified four new vulnerabilities in Windows DoS and one zero-click distributed denial-of-service (DDoS) flaw, classified as “uncontrolled resource consumption.” The vulnerabilities include: - CVE-2025-26673 (CVSS 7.5): High-severity DoS vulnerability in Windows LDAP. - CVE-2025-32724 (CVSS 7.5): High-severity DoS vulnerability in Windows LSASS. - CVE-2025-49716 (CVSS 7.5): High-severity DoS vulnerability in Windows Netlogon. - CVE-2025-49722 (CVSS 5.7): Medium-severity DoS vulnerability in Windows Print Spooler, requiring an authenticated attacker on an adjacent network. These vulnerabilities can incapacitate Windows endpoints or servers, including Domain Controllers (DCs), potentially allowing for the creation of a DDoS botnet. The researchers also discovered a DDoS technique called Win-DDoS that exploits a flaw in the Windows LDAP client’s referral process, enabling attackers to redirect DCs to a victim server for continuous redirection. This method can leverage public DCs globally, creating a large, untraceable DDoS botnet without specialized infrastructure. Additionally, the researchers examined the Remote Procedure Call (RPC) protocol and found three new zero-click, unauthenticated DoS vulnerabilities that can crash any Windows system. They also identified another DoS flaw exploitable by any authenticated user on the network. The researchers released tools named “Win-DoS Epidemic” to exploit these vulnerabilities, highlighting the need for organizations to reassess their security measures regarding internal systems and services like DCs.

Fast Startup might actually be slowing your PC down

Fast Startup on Windows enhances boot times by placing the computer in a hibernation-like state, saving the system state to disk for quicker startups, but does not preserve open programs and processes. Disabling Fast Startup is advisable for users with modern SSDs unless they experience noticeable slowdowns. Fast Startup circumvents traditional shutdowns, which are necessary for proper power cycling of components, potentially leading to system issues over time. It can disrupt Windows updates, causing instability and missing features, making it wise to keep it disabled for regular updaters. For dual-boot systems with Windows and Linux, Fast Startup should be disabled to avoid boot issues and potential data corruption. It can also exacerbate wake-from-sleep problems, leading to slower wake times and peripheral malfunctions. Users with modern NVMe SSDs may find that Fast Startup offers minimal advantages and could even result in longer boot times.
