Refreshing the root of trust: industry collaboration on Secure Boot certificate updates

Secure Boot is a security feature in Windows and Windows Server that protects devices from untrusted software at startup. It has been in operation since 2011 and relies on certificates embedded in a PC’s firmware. The original Secure Boot certificates will begin to expire in late June 2026. New certificates are being rolled out through regular Windows updates for supported devices, with OEMs preparing new devices with updated certificates since 2024. If devices do not receive the new certificates before the expiration of the old ones, they will continue to function but will enter a degraded security state, limiting future protections. Users generally do not need to take action, as updates will be installed automatically, but some specialized systems may require separate firmware updates. Organizations can monitor the update status through the Windows Security App and should ensure devices are running the latest updates and firmware. Support is available for individuals and organizations facing issues during the update process.

How to Disable Windows 11 Defender: Temporary and Permanent

Microsoft Defender Antivirus is the built-in security solution for Windows 11, protecting against viruses, malware, and ransomware. Users may need to disable it temporarily or permanently for various reasons, including software installation, penetration testing, performance issues, transitioning to third-party antivirus solutions, or troubleshooting conflicts. Temporary disabling can be done through the Windows Security app, which will automatically re-enable after a restart. Permanent disabling requires changes in Group Policy, applicable only to Windows 11 Pro, Enterprise, and Education editions, and necessitates disabling Tamper Protection first. Another method for permanent disabling is installing a third-party antivirus, which automatically deactivates Defender's real-time protection. Windows 11 Home users cannot use Group Policy for permanent disabling but can still temporarily disable Defender or install a third-party antivirus. Disabling Defender exposes the system to threats, and users should ensure they have alternative protection in place. Major Windows updates may reset Defender settings, and caution is advised when modifying system settings.

Is turning off Windows Security a bad idea in 2026? A PC expert’s bottom line

Windows Security is a comprehensive security suite for Windows users that monitors downloads, blocks threats, and quarantines malware. Users may need to disable it temporarily to install third-party software or games that are mistakenly flagged as threats. Permanent deactivation is typically for advanced users who may replace it with another security suite, but it increases vulnerability to online threats. To temporarily disable Windows Security, users can toggle off Real-time protection in the Windows Security app. For permanent deactivation, Windows 11 Pro users can use the Local Group Policy Editor, while Home users must edit the Registry. Creating a restore point before making changes is recommended for safety. Disabling Windows Security, even temporarily, should be done with caution to avoid increased risk of infections.

Microsoft Eases Windows 11 Smart App Control with Toggle Option

Microsoft's Smart App Control feature in Windows 11 is designed to evaluate and block potentially harmful applications by cross-referencing them against a database of known safe software. Initially, it required a clean installation to enable or disable, which hindered its adoption. Recent updates have removed this requirement, allowing users to toggle the feature on or off directly through the Windows Security app without a system reset. This change addresses user complaints and enhances usability, particularly for developers and IT professionals managing multiple devices. The feature employs artificial intelligence for real-time decisions on app safety and integrates with other Microsoft security tools. Feedback from the tech community has been positive, highlighting the update as a significant improvement in balancing security and user flexibility.

How Your Computer Protects Itself from Viruses and Cyberattacks

Virus protection is essential in the digital landscape due to threats like ransomware, phishing, spyware, and trojans that can compromise personal data and financial security. Cybercriminals continuously innovate, leading to potential malware infections that can steal sensitive information, lock files for ransom, or degrade device performance. Windows includes Microsoft Defender Antivirus, which provides real-time protection, automatic updates, cloud-based scanning, and firewall features. macOS offers built-in security tools such as XProtect, Gatekeeper, and the Malware Removal Tool, alongside regular updates. Linux distributions like Ubuntu are designed with security in mind, featuring regular patches, AppArmor, and optional antivirus tools. Key features to look for in antivirus software include real-time scanning, firewall protection, web protection, email scanning, automatic updates, and parental controls. While built-in solutions are often sufficient for everyday users, advanced users may benefit from third-party antivirus software. Best practices for maintaining cyber hygiene include keeping software updated, avoiding unverified applications, using strong passwords, enabling two-factor authentication, and regularly backing up data.

I tried a “kinder” Windows 11 experience with AtlasOS, and this is how it should be

Windows 11 has faced criticism for its telemetry features, mandatory Microsoft Edge inclusion, and resource-consuming background processes that can hinder performance. AtlasOS offers a structured setup process requiring a clean installation of Windows 11 with a local account. Users download the AME Wizard and Atlas Playbook from the AtlasOS website to apply modifications, including disabling Windows Security features and replacing Microsoft Edge with alternative browsers like Brave or Firefox. After installation, AtlasOS modifies the desktop experience, aligning the taskbar to the left and introducing a new wallpaper. It disables animations for faster application opening times and optimizes power plans for performance. Bing search is removed from the search bar, enhancing search efficiency. Privacy is prioritized by disabling telemetry services and location permissions. Performance tests show that AtlasOS stabilizes CPU usage and slightly reduces memory consumption compared to standard Windows. Benchmark results indicate minor performance improvements, with AtlasOS scoring slightly higher in Geekbench 6 but comparable in Cinebench 2024. Users should manage expectations regarding performance gains, as the primary advantage lies in an improved user experience rather than significant speed increases.
