Here’s when Windows 11 26H2 will roll out, and what’s actually new on existing PCs

Windows 11 26H2 is expected to be released in October 2026 as an enablement package, primarily serving as a servicing update to enhance stability for enterprise users rather than introducing significant new features. The support for Windows 11 24H2 will end on October 13, 2026, while 25H2 will be supported until October 12, 2027. Windows 11 26H2 will integrate into the existing servicing model of 24H2 and 25H2, allowing users to upgrade quickly with a small update size of 174KB. The system requirements for 26H2 will remain the same as its predecessors. New features include the rebranding of Windows Backup to "Windows settings backup and restore," which will automatically back up user settings and select personal files to the cloud by default. Another feature, Point-in-time restore, will be enabled by default for 26H2 users, allowing the creation of system restore points. This update aims to provide a consistent user experience and enhance business continuity without being a full operating system upgrade.

What Prevents Zero-Day Exploits? A Practical Guide to Stopping Unknown Threats

Zero-day exploits are attacks that take advantage of previously unknown software vulnerabilities before a vendor can issue a patch. These exploits pose significant challenges because organizations cannot address vulnerabilities they are unaware of, and traditional security measures may not effectively identify them. Zero-day vulnerabilities are distinct from zero-day exploits; the former refers to the software flaw itself, while the latter is the method used by attackers to exploit that flaw. Zero-day exploits are particularly dangerous because they give attackers a temporary advantage, allowing them to compromise systems before defenders can respond. These exploits are commonly used in advanced attacks, including ransomware campaigns and espionage. The lifecycle of a zero-day exploit typically involves discovering a vulnerability, weaponizing it, delivering the exploit, executing malicious code, and achieving the attacker's objectives. Traditional antivirus solutions may not consistently prevent zero-day exploits, as they primarily focus on known threats. Endpoint Detection and Response (EDR) platforms provide visibility and detection but do not inherently prevent exploitation. Effective prevention strategies emphasize stopping the exploitation techniques themselves, rather than solely relying on detection. Memory-based attack prevention is a key approach, as all exploits must execute within memory. This method disrupts exploitation techniques and can protect against unknown vulnerabilities. Best practices for preventing zero-day exploits include reducing the attack surface, enforcing least privilege, maintaining aggressive patch management, strengthening identity security, deploying prevention-based endpoint protection, and maintaining a layered security strategy.

Windows 11 Secure Boot certificates have expired, and Microsoft says what to do next

Microsoft held its OEM Secure Boot Office Hours event on July 15, where engineers collaborated with OEM representatives from companies like Acer, Asus, Cisco, Dell, and HP. IT administrators were able to ask live questions about the Secure Boot 2023 rollout. The discussion thread became a detailed technical record, especially following the expiration of the first certificates three weeks prior. Concerns raised by IT admins included BitLocker recovery loops, stuck confidence ratings, and unhelpful Intune error codes. Key facts include: - Devices offline for long periods will still receive the 2023 certificates upon reconnecting to Windows Update. - Devices with existing 2023 certificates in firmware will switch to the new boot manager after the latest Windows patches are installed. - A new script, Detect-SecureBootCertUpdateStatus.ps1, is available in Windows for checking certificate status. - BIOS updates may reset a device’s confidence rating to unrated, which is normal and does not indicate certificate failure. - Admins should edit the AvailableUpdates registry key, not the AvailableUpdatesPolicy, which is managed by Intune and Group Policy. - A licensing bug affecting AvailableUpdatesPolicy on devices upgraded from Pro to Enterprise was resolved by Microsoft in 2026. - BitLocker recovery is not typically linked to the certificate update process but may relate to firmware or PCR issues. - Dell and HP provided guidance on which BIOS versions include the 2023 certificates for their newer models. - Older HP EliteBook 840 G5 units require a manual update package for the new certificates. - Eligible devices can still receive the 2023 certificates in the future, and Surface devices released from 2024 onward come pre-equipped with them. - Microsoft confirmed that devices running 2011 certificates will not lose the ability to receive the 2023 chain. - The Microsoft Corporation KEK CA 2011 and Microsoft UEFI CA 2011 certificates have expired, with the Microsoft Windows Production PCA 2011 set to expire on October 19, 2026.

Point-in-Time Restore for Windows 11 is Generally Available

Microsoft has rolled out the Point-in-time restore feature for Windows 11, enhancing recovery capabilities. Users need to install the June Week D preview update to access it, and the rollout is a Controlled Feature Release (CFR), meaning availability will vary by device. This feature is available in Windows 11 Enterprise, Pro, and Home editions, allowing users to revert systems to a prior state quickly. It offers automatic restore points, improved reliability, integrated management through the Settings app, lower storage impact, and future remote management capabilities via Intune. For Windows 11 Home and Pro users, Point-in-time restore is enabled by default in versions 24H2 and 25H2, and can be managed in the Settings app under System > Recovery > Point-in-time restore.
