Microsoft released three out-of-band Windows 11 updates on October 26, 2026, to address a compromise involving eight intermediate CA private keys from eMudhra, which could allow attackers to forge TLS certificates. These updates, specifically for air-gapped or locked-down machines, will not be visible to most users as they are distributed through the Microsoft Update Catalog and not through regular Windows Update. The eMudhra security issue was reported on October 17, leading to a coordinated response from major tech companies to block the affected certificates. IT admins managing offline systems need to ensure their packages include the updated Disallowed Certificate Trust List and verify any certificates that chain to the removed roots, while average users are advised to take no action

Microsoft has released an urgent out-of-band security update for .NET, covering versions 8, 9, 10, and the release candidate 11 RC3, in response to a critical buffer overflow vulnerability (CVE-2026-111497) in the Brotli decompression algorithm. This flaw is rated CVSS 10 and poses risks such as information disclosure and remote code execution, affecting applications that handle Brotli data. Additionally, the update addresses two previously incomplete fixes for memory corruption and remote code execution vulnerabilities, as well as a privilege escalation issue related to Linux tarballs. Developers are urged to promptly apply these updates before the end-of-support deadline for .NET 8 and 9 on November 10, 2026

Microsoft has released three coordinated PowerShell servicing builds, which mainly consist of a .NET SDK runtime bump without introducing new features. These updates are crucial as two of the lines, 7.4 LTS and 7.5, will reach end-of-support on November 10, 2026, after which they will no longer receive updates, while the 7.6 LTS line will remain supported until November 2028. The patches issued today inherit the security fixes from a previous release in October but do not address any new vulnerabilities. Users are encouraged to update to these builds and plan their migration to the supported 7.6 LTS line before the upcoming deadline

On October 23, Microsoft released five new Windows 11 Insider Preview builds, including updates for the Beta and Experimental channels, as well as dedicated tracks for ARM and Future Platforms. Key features of the updates include a redesigned File Explorer right-click menu, a built-in internet speed test in Quick Settings, and phone controls for Android devices.

Additionally, the builds carry improvements in accessibility, bug fixes, and the introduction of Unicode 17.0 support, though users should note that not all features may be available immediately due to staged rollouts

PowerShell 7.6.8 has been released, marking the latest servicing update for the 7.6 LTS channel, with a significant change being the removal of the in-product Update Notification. Microsoft has deemed this feature redundant due to the reliability of updates through Microsoft Update and MSIX auto-update channels, and the removal also addresses a startup crash issue affecting certain console and locale configurations. Alongside the removal, the build toolchain has been updated to .NET SDK 10.0.402 for improved security. While there are no breaking changes in this release, users are encouraged to transition to PowerShell 7.6 for production environments as earlier versions approach their end-of-life

Microsoft PowerToys v0.102.2933.0 has been released as the final stable update, featuring new mouse utilities like Mouse Button Lock and CursorHide, alongside a significant revamp of the Command Palette and enhancements in scriptability.

This release marks a significant moment as it offers a production-ready preview of .NET 11, which is expected to launch in November 2026, and comes with a go-live license that allows developers to use it in real-world applications. Microsoft advises developers to immediately patch their applications on .NET 8, 9, and 10 due to the large number of security fixes and the imminent end of support for .NET 8 and 9 within months. The updates also include various enhancements across libraries and frameworks, positioning .NET 11 as a more robust and feature-rich option moving forward

Microsoft has released PowerShell versions 7.6.7, 7.5.12, and 7.4.21, which include two shared fixes related to the handling of a corrupt configuration file and a session-restriction check for the Show-Command cmdlet. However, the pressing issue is that versions 7.4 and 7.5 will lose all support, including security updates, on November 10, 2026, making it critical for users to migrate to version 7.6 LTS, supported until November 2028. The updates are considered routine, with no significant security implications or extensions of support, and mainly address minor functionality improvements. Users are advised to upgrade before the deadline, and the easiest method is through WinGet, while ensuring they check their installation type and verify updates post-installation

Microsoft has released PowerToys Preview v0.102.2851.0, introducing a searchable character reference guide for Quick Accent and improved screen recording stability for ZoomIt. The update also includes a rollback of a stricter code-analyzer policy to prioritize build stability ahead of the upcoming stable release. With enhancements like real-time audio pacing and easier character copying, these changes reflect ongoing improvements in the utility's functionality. The release highlights Microsoft's increasing reliance on AI-assisted development for maintenance tasks, while emphasizing that users on stable versions do not need to rush into the preview build unless they want early access to new features
