5 reasons why Windows 11 Pro is so much better than Windows 10

Windows 11 Pro is actively promoted by Microsoft as the future operating system, with Windows 10 reaching its end of support in October 2025, meaning no more free security updates or technical assistance. Windows 11 Pro offers enhanced built-in security features, including mandatory TPM 2.0 and Secure Boot, making it a more secure choice. It includes useful features like BitLocker for drive encryption, Remote Desktop support, Group Policy controls, and Hyper-V for creating virtual machines. Windows 11 Pro also enhances productivity with features like Snap Layouts and File Explorer tabs for better organization and navigation.

Microsoft’s Secure Boot certificates expire in June 2026, but older PCs may never get the fix

Every Secure Boot-enabled Windows PC relies on cryptographic certificates issued by Microsoft in 2011, embedded in the motherboard's firmware, to ensure a secure boot process. The first of these certificates will expire on June 24, 2026, which will affect the ability to receive future security updates for critical components of the Windows startup process. Microsoft is rolling out replacement certificates through Windows Update, marking a significant security maintenance effort. Secure Boot operates as a chain of trust with certificates stored in the motherboard's UEFI firmware, validating software before the operating system loads. The Platform Key (PK) is at the top of this chain, followed by the Key Exchange Key (KEK) and the Signature Database (DB). The replacement certificates introduced in 2023 restructure certificate management, separating responsibilities among different certificate authorities to enhance the trust model. Not all PCs are affected by the upcoming expiration; newer devices manufactured since 2024 already have the new certificates. Windows 10 users face challenges as support for this version ends in October 2025, and they will not receive the new certificates unless enrolled in Extended Security Updates. Home users should ensure their PCs are set to receive updates automatically, while enterprise environments require coordination for firmware updates before the Windows certificate update.

Microsoft’s Secure Boot certificates expire in June 2026, but older PCs may never get the fix

Every Secure Boot-enabled Windows PC relies on cryptographic certificates issued by Microsoft in 2011 for boot process integrity. The first of these certificates will expire on June 24, 2026, impacting the ability to receive future security updates. Microsoft is rolling out replacement certificates through Windows Update, requiring collaboration between Microsoft, PC manufacturers, and users. Three critical certificates will expire: the Microsoft Corporation KEK CA 2011 and Microsoft UEFI CA 2011 in June 2026, and the Microsoft Windows Production PCA 2011 in October 2026. The new certificates introduced in 2023 have a restructured functionality to enhance security. Not all PCs are affected; newer devices manufactured since 2024 come with the new certificates. Windows 10 users face challenges as support ends in October 2025, and unsupported devices will not receive updates. Home users should ensure automatic Windows updates and check for firmware updates, while enterprise environments must verify firmware updates before applying certificate updates. The first certificate expiration is on June 27, 2026.

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.
