Microsoft has released out-of-band updates for Windows 11 versions 26H1, 25H2, and 24H2 to address security vulnerabilities and improve system performance. The KB5129194 patch for version 26H1 fixes a critical elevation-of-privilege vulnerability (CVE-2026-62721) related to the Windows User-Mode Power Service (UMPS). The KB5129195 update for versions 25H2 and 24H2 also addresses a similar UMPS vulnerability and resolves a connection issue with Remote Desktop Services. Additionally, the updates fix problems with multichannel audio features on certain USB Audio Class 1.0 devices. These updates include enhancements from the September 2026 Patch Tuesday release, such as Taskbar customization, a faster Windows Search experience, and new Start Menu options. Users with unmanaged PCs will receive these updates automatically but can also check for updates manually.

Microsoft plans to automatically activate Memory Integrity on a broader range of eligible systems starting October 2026, rolling it out through standard Windows quality updates. Prior to activation, Windows will assess hardware, drivers, and performance to ensure compatibility. Memory Integrity, part of Virtualization-based Security (VBS), uses the Windows hypervisor to create a secure environment for integrity checks on kernel code. Compatibility with drivers is crucial, as many older applications may not meet the stricter standards required for HVCI. Potential compatibility issues may arise with anti-cheat solutions, third-party input methods, and banking protection programs, which could lead to software malfunctions or boot failures. A readiness check will evaluate hardware compatibility, with eligible systems including Intel processors from the 8th generation, AMD processors from Zen 2, and Qualcomm Snapdragon 8180 or newer, along with specific RAM and storage requirements. The rollout will be gradual, and users who previously disabled HVCI will not face unexpected reactivation. Microsoft recommends updating affected applications or drivers in case of compatibility issues.

The Group Policy Editors gpedit.msc and gpmc from the RSAT tools are experiencing functionality issues in Windows 11 due to a bug that causes an overflow error, resulting in incorrect configurations being saved. This issue was first reported by Mark Heitbrink to Microsoft in March 2026, but he has not received feedback. The bug appears to be unique to Windows 11 clients, as tests on Windows Server did not show the problem. Mark documented the bug with submission number VULN-180447 and case number 111952. He described how to reproduce the issue involving the group policy "Delay Foreground download from http" and the decimal value "4294967295," which gets altered to "2147483647" on Windows 11. Mark speculated that the issue might be due to the Windows client using the INT data type instead of unsigned INT, leading to an overflow. He noted that over 50 policies are affected by this MaxValue issue across various components.

The KakaoTalk app is experiencing a surge in popularity in Russia, largely due to the Kremlin's actions against competing messaging services like Telegram, which has faced potential bans and restrictions. KakaoTalk, with an average of 46.35 million monthly active users in South Korea, has risen to the top of Russia's App Store as an alternative after reports of Telegram's functionality issues. Russian authorities are blocking Western messaging services like WhatsApp and Discord, making KakaoTalk a viable option for users seeking privacy. By late March, KakaoTalk reached No. 2 on Russia's App Store and No. 4 in the Social Networking category. Despite needing to comply with South Korean data requests, KakaoTalk's servers being located outside Russia may appeal to privacy-conscious users.

Microsoft has stopped distributing V3 and V4 printer drivers through Windows Update as of last month, affecting printers up to 12 years old. Support for these drivers will end in January 2026, as they were marked as deprecated in September 2023. Users with printers relying on these drivers may experience functionality issues after support ends. Printer manufacturers are now responsible for providing driver updates via their websites, but existing drivers will remain operational. Microsoft confirmed that vendor-supplied drivers can still be installed using separate packages. Most modern printers do not use V3 and V4 drivers, as they are typically over a decade old. Microsoft aims to enhance system security and streamline the printing process by phasing out outdated drivers. After July 2026, Windows will prioritize built-in printer drivers during installation, and from July 2027, manufacturers will no longer be able to submit driver updates to Windows, although Microsoft will continue to provide critical security updates for existing drivers.
