Windows 10 will be retired on October 14, 2025, after which it will no longer receive software and security updates. Currently, 53.2 percent of Windows computers worldwide run on Windows 10, while 43.2 percent use Windows 11. Users can upgrade to Windows 11 for free or by purchasing a new PC, but many older machines may not meet the minimum system requirements. Microsoft has reached out to Windows 10 users via email to remind them of the end of support and has introduced a new feature in Windows Backup to help transfer data to a new PC. This feature, labeled “Transfer information to a new PC,” is expected to be rolled out across all Windows 10 builds. Microsoft has also announced that Microsoft 365 apps will continue to receive security updates for an additional three years after the retirement date.

Defendnot is a tool that disables Windows Defender by using the Windows Security Center (WSC) API, presenting itself as a legitimate antivirus solution. It was created by a developer named “es3n1n” and follows the removal of a previous tool called “no-defender.” The tool engages directly with WSC, which disables Windows Defender when third-party antivirus software is installed to avoid conflicts. Defendnot was developed through reverse engineering of the WSC service and involves understanding how WSC verifies processes. It registers a phantom antivirus product using COM interfaces and undocumented Windows APIs, leading Windows to disable its built-in protection. The tool requires administrative privileges to operate and adds itself to autorun to maintain its functionality after a reboot. Security experts express concern about its potential misuse by malware authors, while it also provides insights into vulnerabilities in Microsoft’s security architecture.

Microsoft has introduced a suite of Windows experiences for Copilot+ PCs, featuring AI agents that help users adjust settings on their computers by interpreting user intent and automating tasks with consent. Users can communicate in natural language to receive guidance or have changes executed directly. This feature will initially be available to English-speaking Windows Insiders on Snapdragon-powered devices, with plans for broader support. Additionally, Microsoft is enhancing Windows search capabilities and expanding Click to Do actions, allowing users to schedule meetings, send messages, consult M365 Copilot, convert data in Excel, and draft documents in Word. Creative tools like Photos, Paint, and the Snipping Tool are receiving updates, including dynamic lighting controls in Photos, a sticker generator in Paint, and new capture capabilities in the Snipping Tool. Upcoming features for Windows 11 Insiders include a phone companion for the Start menu, AI-driven actions in File Explorer, and a new writing function in Notepad for generating text from prompts. Microsoft is also testing a "Draw & Hold" feature in the Snipping Tool and has introduced a text rewriting tool called "Rewrite."

Unexpected crashes on Windows 11 version 24H2 have been reported, resulting in a secure kernel fatal error with the blue screen exception error code 0x18B. Microsoft has introduced a Known Issue Rollback (KIR) to address this issue by rolling back specific updates. For personal or non-managed computers, the fix will be automatically deployed via Windows Update, and users are advised to restart their PCs. For enterprise devices, IT departments must install the KIR Group Policy, found under Computer Configuration > Administrative Templates, and a restart of affected devices is required. The blue screen bug appeared after a Patch Tuesday update that addressed 134 security vulnerabilities, including a zero-day flaw.
