We’re not the only ones saying it: Windows 11 desperately needs a single privacy toggle

The process of enhancing privacy on Windows 11 involves navigating a complex array of settings aimed at limiting data collection by Microsoft. During the out-of-box experience, users encounter a privacy page that offers choices regarding diagnostics, tailored experiences, advertising IDs, and location services, but the actual privacy controls are fragmented and often ineffective. Microsoft's integration of services like OneDrive and its backup system complicates privacy management, and while users can adjust diagnostic data settings to reduce telemetry, complete elimination of data collection is not possible across most editions. This complexity leaves users uncertain about the extent of their data exposure.

Windows 11 Home vs Pro: Expert Issues Upgrade Advice

Windows 11 Home and Windows 11 Pro share consistent performance, with both versions offering the same kernel, gaming features, and applications. Key functionalities such as Copilot, Windows Defender, Secure Boot, and TPM 2.0 protections are available on both editions, assuming hardware requirements are met. Windows 11 Home is simpler for most consumers, performing updates seamlessly and allowing free upgrades from eligible Windows 10 devices. Windows 11 Pro offers enhanced control capabilities through the Group Policy Editor, allowing for update deferrals and more extensive system management. Pro includes BitLocker device encryption, centralized management features, and the ability to join domains and integrate with Azure Active Directory. It also supports virtualization features like Hyper-V and Windows Sandbox, which are not available in Home. Pro can serve as a host for remote desktop connections, while Home can only connect to remote PCs. In terms of hardware limits, Windows 11 Home supports up to 128GB of RAM and one CPU socket, while Pro supports up to 2TB of RAM and two CPU sockets. The retail prices are approximately 9 for Home and 9.99 for Pro, with upgrade options available. For general users, Windows 11 Home is recommended, but Pro is advisable for those needing remote desktop hosting, BitLocker management, update deferrals, or virtualization capabilities.

Microsoft Adds Copilot AI to Windows 11 File Explorer Amid Privacy Debates

Microsoft is enhancing its artificial intelligence capabilities in Windows 11 by potentially integrating its Copilot AI into File Explorer, as indicated by recent code discoveries in insider preview builds. This integration may introduce a new Copilot button or sidebar, allowing users to engage with AI for contextual queries about files, such as summarizing documents or organizing folders. Concerns have been raised regarding privacy and system performance, as the AI could access local files. The integration may also include chat capabilities, prompting fears of data exposure. Microsoft has assured users that Copilot prioritizes local processing and operates with consent. However, critics worry about the potential for intrusive AI suggestions and the possibility of forced updates. The integration is expected to leverage Microsoft's agentic AI framework and may require advanced hardware for optimal performance. Financial incentives, such as Copilot Pro subscriptions, are also a factor in this strategic push. User feedback will be crucial in determining the success of this integration, with mixed reactions from the tech community regarding privacy and control.

Samsung fixes the Secure Folder flaw that let anyone see what apps you’re hiding

Samsung has addressed a vulnerability in its Secure Folder feature that previously allowed individuals with physical access to a device to view hidden apps and photos. This flaw arose from the Secure Folder being classified as a "work profile," which certain system components did not recognize as secure. With the release of One UI 8, Samsung has reclassified Secure Folder as a "private" profile, ensuring it is treated as a secure space by Google’s components. This change prevents unauthorized access to its contents, but the Secure Folder must be fully hidden for enhanced protection. However, it currently does not integrate with third-party launchers, as Samsung has not yet implemented the necessary APIs for compatibility.
