Microsoft Releases Emergency Windows 11 Hotpatch to Fix Remote Code Execution Flaw

Microsoft has released an out-of-band hotpatch update, KB5084597, to address three critical remote code execution vulnerabilities (CVE-2026-25172, CVE-2026-25173, CVE-2026-26111) in the Windows Routing and Remote Access Service (RRAS) management tool. This update is specifically for Windows 11 Enterprise devices in the hotpatch program that did not receive fixes during the March 2026 Patch Tuesday. The vulnerabilities can be exploited by an authenticated attacker within the domain, potentially leading to remote code execution. Hotpatch updates apply fixes through in-memory patching without requiring a device reboot, making them suitable for mission-critical devices. The update is applicable to Windows 11 versions 24H2, 25H2, and Windows 11 Enterprise LTSC 2024, and will be automatically installed on enrolled devices without a restart. Non-enrolled devices received the fix via the standard March 10 Patch Tuesday update.

Microsoft releases Windows 11 26H1, but it’s not for existing PCs. Windows 11 26H2 is coming for all PCs

Microsoft has confirmed the existence of Windows 11 26H1, which will roll out exclusively on new PCs equipped with Snapdragon X2 chips starting in early 2026. This version is tailored for ARM-based devices and will not be available for download or installation on current PCs. Windows 11 26H1 does not introduce new features but focuses on performance and battery life improvements. It may also be optimized for Nvidia N1X chips, which are expected to release in Q1 2026. Windows 11 26H2 is set to roll out for existing hardware in October 2026 as a normal yearly update. It will be based on the same core platform as previous versions 24H2 and 25H2, while 26H1 operates on a different core, meaning there is no upgrade path from 26H1 to 26H2. Both versions will unify under Windows 27H2 in 2027.

The latest Insider build of Windows 11, KB5072046, updates the operating system to build 26220.7535 and is available to Insiders in the Dev and Beta channels.

Users can press Narrator key + Ctrl + D to describe a focused image or Narrator key + Ctrl + S for a full screen description. Microsoft has also introduced a policy for system administrators to uninstall the Microsoft Copilot App under specific conditions, applicable to Enterprise, Pro, and EDU SKUs. Various fixes have been implemented, including resolving issues with the Start menu, File Explorer, input using the Snipping Tool, print dialogs, and Windows Update settings.

Still running Windows 10? Here’s why that’s a bad idea

Hundreds of millions of computers are still using Windows 10, despite it reaching its end-of-support deadline. An Extended Security Updates (ESU) subscription is available for free until October 2026, providing updates to help protect against security threats. By early 2021, around 100 million PCs were still running Windows 7, which had ceased receiving updates in January 2020, making them vulnerable to cyberattacks from groups like Digital Shadows, LockBit, Conti, and Vice Society. Notable incidents include the PrintNightmare flaw in July 2021, which led Microsoft to issue a patch for Windows 7, and the WannaCry attack in 2017, which targeted Windows XP machines. Microsoft releases monthly security fixes, and vulnerabilities like CVE-2025-62215, identified in November 2025, have been categorized as "Exploitation Detected." While current vulnerabilities require local access, history suggests that remote attacks may soon occur, posing severe risks to unpatched systems.

Microsoft releases Windows 10 KB5071546 extended security update

Microsoft has released the KB5071546 extended security update, addressing 57 security vulnerabilities, including three critical zero-day flaws. This update is intended for Windows 10 Enterprise LTSC users and those in the ESU program. Users can install it by navigating to Settings, selecting Windows Update, and performing a manual 'Check for Updates'. The update will automatically install and prompt for a restart.

The update focuses on security enhancements and bug fixes, including a remote code execution vulnerability in PowerShell (CVE-2025-54100). PowerShell 5.1 will now issue a warning when using the "Invoke-WebRequest" command to alert users about potential script execution risks. Users are advised to use the -UseBasicParsing command line argument to prevent embedded scripts from executing. Microsoft has confirmed there are no known issues with this update.
