A Windows 11 bug blocks all updates since February. Here’s what to do

A segment of Windows 11 users has been unable to receive updates since February due to issues stemming from the January Preview Update, which caused download timeouts. This has resulted in missed security patches and critical updates related to Secure Boot certificates. Users may experience crashes during the update process, indicated by the error code 0x80010002. To check if affected, users can view their update history in Settings; if no updates have been installed since January and updates have not been paused, they are likely impacted. Microsoft is working on a fix linked to download timeout changes and firewall settings. A Known-Issue Rollback (KIR) can be executed to revert to a previous state before the problematic update, restoring normal functionality. This rollback is available for specific Windows 11 versions and Windows Server 2025.

5 Android App Permissions You Should Never Allow

Users should be cautious when granting permissions to applications on Android devices, as extensive access can lead to security vulnerabilities. Apps with accessibility permissions can perform actions like hacking passwords and altering device settings without user consent. Overlay permissions allow apps to display content over others, which can be exploited by malicious apps to trick users into providing sensitive information. Installing apps from unknown sources poses risks to device security and privacy. Usage data access enables apps to monitor user activity, which can be sold to advertisers. Granting access to contacts and SMS can lead to privacy concerns, as this information can be exploited by malicious entities. Users are advised to regularly review and manage app permissions to mitigate potential threats.

Android Apps on Windows 11: Safe Alternatives After WSA

In 2025, Microsoft announced it would discontinue support for the Windows Subsystem for Android (WSA), making Android applications non-functional on Windows 11. This decision surprised many users in Indonesia who relied on these applications. HP developed a guide outlining secure alternatives to WSA, which included reputable Android emulators like BlueStacks, LDPlayer, and NoxPlayer, as well as native Windows alternatives such as Microsoft Teams and Microsoft 365 apps. Users were advised against unverified APK sideloading, unofficial emulators, and modified apps due to security risks. Microsoft’s end of support means no further security updates or bug fixes will be provided, and integration with the Amazon Appstore will cease. Users can continue using WSA apps, but they will be exposed to potential security threats. To migrate data from WSA, users were instructed to inventory apps, research alternatives, and export app data before performing a clean uninstall. Best practices for running Android apps safely on Windows included downloading from official sources and keeping software updated.

Microsoft Confirms Critical Windows Update Error Disrupting Global Systems

Microsoft has confirmed a critical bug in its latest cumulative update, affecting millions of Windows 10 and Windows 11 users. The issue leads to a "Restart and Shut Down" loop, preventing users from completing the update and locking them out of their devices. This disruption is particularly severe for corporate IT departments, with reports of entire office networks being paralyzed. The problematic update, identified as KB5037853, was meant to address security vulnerabilities but has caused systems to display an endless "Update and Restart" message. Some users experience a "Blue Screen of Death" (BSOD) and may be forced into "Recovery Mode." Microsoft is working on a "Known Issue Rollback" (KIR) to automatically undo the problematic code for consumer machines, while enterprise users may require manual intervention. The downtime is projected to result in significant financial losses, with large enterprises potentially losing up to ,600 per minute of unplanned downtime. Affected versions include Windows 11 22H2, 23H2, and Windows 10 22H2. Symptoms include failure to shut down, BSOD on boot, and missing Start menu icons. The estimated downtime ranges from 4 to 12 hours, depending on IT response speed. Critics have raised concerns about Microsoft's development process, suggesting it places users in the role of beta testers.

You shouldn’t delay your Windows 11 updates, experts reveal

Experts advise against postponing Windows updates, as Microsoft has introduced features allowing users to control when updates occur. Users can pause updates for up to 35 days indefinitely, but delaying updates can lead to security vulnerabilities. Microsoft releases several types of updates: security updates, feature updates, quality updates, driver updates, optional updates, out-of-band updates, and zero-day updates. Zero-day updates are critical and should be installed immediately to avoid exploitation. Recent reports indicate that critical OS patching for Windows 10 and 11 is lagging by an average of 256 days, increasing the risk of cyber incidents.

Microsoft is changing the rules of the game: updates are no longer forced in Windows 11

Windows 11 has introduced a new update management model that allows users to pause updates indefinitely, transforming the previous 35-day limit into a flexible option. This change addresses user frustrations regarding unexpected reboots and system instability caused by updates. Users can now choose to restart or shut down their systems without automatic updates being installed. This adjustment aligns with Microsoft's strategy to enhance user autonomy, although the company warns that neglecting updates can increase security vulnerabilities. The new features are currently available in test builds, with a wider rollout expected soon.

How to turn off Meta AI (Facebook, Instagram, and WhatsApp)

Meta AI has been integrated into Facebook, Instagram, WhatsApp, and Messenger, enhancing user experiences with features like search functionalities, chat interactions, and content generation. Users express a desire to limit their interactions with Meta AI due to concerns about transparency, privacy, and data security. The AI model is trained on diverse data sources, including public posts and user interactions, raising issues regarding data control. On WhatsApp, personal messages and calls are end-to-end encrypted, while Instagram may share past messages with Meta AI for context. Security vulnerabilities have been reported, including incidents of data mishandling. Currently, there is no comprehensive option to disable Meta AI across all platforms, but users can take steps to limit interactions, such as muting AI prompts and adjusting privacy settings. Users in the E.U. and U.K. can object to certain data uses under GDPR by submitting requests through their Meta accounts. To protect privacy, users are advised to opt out of AI training, limit personal data sharing, and use privacy tools like VPNs.
