Windows 11 finally gets an undo button for your entire PC

Microsoft unveiled its July 2026 Patch Tuesday update, identified as KB5101650, for Windows 11 versions 25H2 and 24H2. The update introduces the Point-in-Time Restore (PITR) feature, allowing users to take full backups and create snapshots every 4 to 24 hours, with snapshots retained for a maximum of 72 hours. PITR can restore local files and applications. Users can now pause Windows updates for up to 35 days. Other enhancements include discreet widget operation, optimized taskbar notifications, faster File Explorer startup, quicker disk image mounting, improved Bluetooth functionality, reduced eye strain through screen tinting, and enhancements in voice control and input capabilities. Not all features will be available immediately after installation, with security-related improvements being deployed universally.

Microsoft Confirms Windows 11 Bug That Can Consume Over 500GB of Storage Through Permission Log File

Microsoft has acknowledged a bug in Windows 11 that causes the Capability Access Manager's write-ahead log file to expand indefinitely, potentially exceeding 500GB of storage on affected devices. This issue is addressed in update KB5095093, which includes builds 26200.8737 and 26100.8737. Users can manually install this update via the optional updates section of Windows Update or wait for its automatic rollout during the July 2026 Patch Tuesday. The Capability Access Manager manages app permissions and logs usage of privacy-sensitive features, but the WAL file continues to grow unchecked on affected systems. The file can reach sizes from 70GB to over 513GB. To check if a system is affected, users can check storage settings or use Robocopy to verify the file size. The update is available through the Optional updates section and will be included in the cumulative update on July 8, 2026. The excessive size of the WAL file can lead to critical storage shortages and related issues, but it does not compromise the security or core functionality of the permission system. Microsoft has not confirmed if Windows 11 26H1 Insider builds are affected.

Windows Update Will Start Showing New Insider Channel System to all Windows 11 Users

The Windows Insider Channel system is expanding to all Windows 11 users via Windows Update, allowing non-Insiders to join the program. The previous Canary, Dev, and Beta Channels will be replaced by the Experimental and Beta Channel options. The Experimental Channel will introduce new features first and allow user feedback to shape developments, while the Beta Channel will provide early access to upcoming features but will discontinue controlled feature rollouts. Microsoft recently released five new builds across the Beta and Experimental Channels, including a new taskbar size setting in the Experimental build 26300.8758 to enhance taskbar customizability.

Your Windows 10 PC just quietly got another year of free support

Microsoft has extended the security updates for Windows 10 users by an additional year, with the new end date for the Extended Security Updates (ESU) program set for October 12, 2027. This extension applies automatically to existing ESU enrollees, and new users can sign up until the deadline. The change was confirmed by a Microsoft spokesperson in an editor's note added to a blog post. The extension does not apply to corporate Windows deployments, which require costly ESU subscriptions that extend support until October 2028.

Microsoft Announces New Insider Builds, a Bit of 26H2 News

Microsoft has released five new Windows Insider Preview builds and updates for Windows 11 version 26H2. Devices in the Experimental channel will soon update to version 26H2, which can be checked in Settings > System > About or using the winver command.

Windows Platform Security and the Race to Secure AI Agents

Microsoft has introduced the Microsoft Execution Containers (MXC) SDK to establish Windows as a reliable operating system for autonomous agents, focusing on containment, identity, and manageability. The MXC framework serves as a policy-driven execution layer for agents on Windows and Windows Subsystem for Linux (WSL), allowing developers to set access permissions using JSON or TypeScript. It employs process and session isolation for agent containment and identity. Future enhancements will include micro-VM support for high-risk tasks and integration with Windows 365 for cloud PC workloads. IT teams can manage MXC policies through Entra ID and Intune, while Defender and Purview provide protection and observability. The MXC framework is built on Microsoft's security initiatives, including Secure Boot and passwordless sign-in, allowing agents to inherit a secure foundation. However, early commentary expresses caution regarding MXC's perception as a comprehensive security solution, noting issues with overly permissive policies and the lack of outbound network filtering. Other platforms, such as Linux, are also enhancing security for agents with kernel-level isolation and secure environments like NVIDIA's OpenShell runtime. Various projects are focusing on agent sandboxes within Kubernetes, employing technologies like gVisor and Kata Containers for isolation. Overall, no singular dominant platform security model for AI agents has emerged, with Windows' MXC still considered nascent compared to existing solutions in Linux and Kubernetes ecosystems.

Microsoft confirms Windows 11 Search will find your apps, not Bing results, even if you make typos

Microsoft has released the Insider Experimental Preview Build 26300.8687 for Windows 11 on June 12, 2026, which improves the Windows Search functionality. The update allows the search tool to accurately locate applications even with misspellings, omitted letters, or partial words. For example, typing “utlook” will yield Outlook as a result. Enhancements in the ranking of settings search results ensure that the most relevant options appear at the top. The update also improves local file search, allowing users to find files like “Severance-S2E5” more effectively. A new feature is being tested that will let users turn off web results in Windows Search, focusing exclusively on local content. Currently, disabling Bing results requires navigating through the Windows Registry, but a toggle in the Settings menu is being introduced for easier access. The June 2026 update has already implemented search enhancements, including returning file results after just two characters and a feature called Search by Substring, which allows users to find files using any segment of a filename.

I dug through the Windows 11 Insider builds for June 2026 and found 7 features worth paying attention to

Microsoft rolled out several preview builds of Windows 11 in early June 2026 as part of the Windows Insider Program, focusing on refining existing functionalities rather than introducing many new features. A new Beta channel for version 26H1 was launched, featuring: - Screen Tint: An accessibility feature that provides a system-wide color overlay to reduce eye strain, accessible through Settings > Accessibility > Vision > Screen Tint, offering six preset colors or custom hues. - Low Latency Profile: Temporarily boosts processor frequency for 1 to 3 seconds during interactive tasks, improving application launch times by up to 40% and interaction times by as much as 70%, operating automatically without manual toggles. - Widgets Experience Update: Widgets now open without hover activation, Taskbar badges are off by default, and alerts are limited until user interaction. The dashboard displays Widgets under "widgets," and badging aligns with the system accent color. - Magnifier Enhancements: Users can input specific zoom percentages directly and access additional zoom presets ranging from 5% to 400%. - File Explorer Changes: Improvements for compatibility, performance, and reliability, including support for paths with double backslashes and quotation marks, and middle-click support for opening folders in new tabs. - Windows Update: Unification of drivers, .NET, and firmware updates with monthly quality updates, reducing required restarts to one per month. - Windows Search Enhancements: Improved handling of typos, missing letters, and partial app names, prioritizing accurate search results even with input errors.
