The Windows 10 deadline most ISVs haven’t planned for yet

Windows 10 Enterprise LTSB 2016 and Windows 10 IoT Enterprise 2016 LTSB will reach their end of support on October 13, 2026, after which they will no longer receive security updates. These operating systems are designed for fixed-function devices like kiosks and point-of-sale terminals, which are often not actively managed, posing risks if the end-of-support date is overlooked. Microsoft offers an Extended Security Updates (ESU) program as a temporary solution, with escalating costs over three years, but it is not intended as a long-term fix. Customers must decide whether to continue paying for ESU, upgrade to newer hardware, or transition away from Windows.

Windows 10’s latest patch keeps your Secure Boot certificates on track

A recent update has been released, addressing security vulnerabilities and improving system functionality. Key improvements include a fix for the Backup feature, resolving an "invalid credentials" error that caused automatic backups to fail when using Server Message Block (SMB). The update also enhances the Secure Boot feature by introducing high-confidence device targeting data, allowing more devices to receive new Secure Boot certificates. This update addresses outdated Secure Boot certificates for Windows 11 and Windows 10 users. The update, identified as KB5120249, is under 1 GB and is available only to PCs enrolled in the Extended Security Updates (ESU) program, which ensures Windows 10 PCs receive security updates until at least October 2027.

ShieldBreak: New Windows Zero-Day Bypasses Microsoft’s RoguePlanet Patch

Chaotic Eclipse, a security researcher, has revealed a proof-of-concept (PoC) for a new vulnerability called ShieldBreak, which is a zero-day flaw in Microsoft Defender that bypasses the patch for the previously identified CVE-2026-50656 (RoguePlanet). This vulnerability could allow attackers to execute code at the SYSTEM level on affected Windows systems. Chaotic Eclipse tested the PoC on the latest versions of Windows 11 and Windows Server 2025, achieving a 100% success rate. Windows 10 and its server editions are not supported by the PoC but remain vulnerable. Microsoft had issued security updates for RoguePlanet, which has a CVSS score of 7.8, affecting the Malware Protection Engine and representing a local privilege escalation issue. Chaotic Eclipse has previously disclosed two other zero-day vulnerabilities, YellowKey and GreenPlasma, which affect BitLocker and the Windows Collaborative Translation Framework, respectively. Microsoft criticized the public disclosure of these vulnerabilities as irresponsible and emphasized the importance of Coordinated Vulnerability Disclosure.

Windows 11’s faster app launches released today, enable it using these steps

Windows 11 introduced the Low Latency Profile feature with the August 2026 security update, enhancing app launch speeds. This feature allows the CPU to quickly reach near-maximum frequency when an application is launched, improving loading times and conserving energy by returning to low-power idle states more rapidly. Initially limited to core Windows shell elements, the August update (KB5121003) expanded this functionality to a wider range of applications. Testing showed significant improvements in app launch times, with no adverse effects on CPU performance or battery life. Users can manually enable the feature using the ViVeTool if it hasn't been rolled out to them yet. Microsoft is also working on optimizing Windows 11 for devices with 8GB of RAM and above by the end of 2026.
