Fix: You’ll need a new app to open this windowsdefender link

The message “You’ll need a new app to open this windowsdefender link” indicates issues with the Windows operating system when the Windows Security app fails to launch via the windowsdefender protocol. This can prevent users from accessing the security dashboard, despite Microsoft Defender continuing to operate in the background. Common scenarios leading to this error include clicking on Virus & Threat Protection, trying to open Windows Security from the Start menu, interacting with a Defender notification, or following the uninstallation of third-party antivirus software. Root causes may include corrupted Windows Security app registration, damaged system files, third-party antivirus interference, misconfiguration of the Security Center service, or malware interference. To resolve the issue, users can verify that required services are running, repair system files using SFC and DISM, re-register the Windows Security app, check for third-party antivirus conflicts, and perform a repair installation of Windows. Specific steps include checking the status of the Security Center and Microsoft Defender Antivirus Service, executing repair commands in CMD, re-registering the Windows Security app using PowerShell, uninstalling third-party antivirus software, and performing an in-place upgrade if necessary.

Microsoft will let you pause Windows Updates indefinitely, 35 days at a time

Microsoft has introduced enhancements to the Windows Update system, allowing users to delay updates for up to 35 days and reset this delay multiple times without restrictions. Descriptive titles for driver updates will now specify the device class, and options to restart or shut down without triggering updates will be consistently available in the power menu. Additionally, updates will be consolidated to reduce the number of reboots, with downloads occurring in the background before coordinated installation and restart.

‘A performance tool that requires a graduate seminar before breakfast has already lost the room’: Why Windows Task Manager looks like it’s getting CPU usage wrong

Users have expressed frustration with Windows 11's Task Manager CPU usage reporting, believing it relies only on base clock speeds. Dave Plummer, the original architect of Task Manager, indicated that discrepancies may arise from average calculations and inherent compromises in the metrics. In response, Microsoft announced a fix in a recent Preview build, stating that Task Manager will now use standard metrics for CPU utilization across all pages to align with industry standards. Plummer also suggested a distinct Windows mode for power users to enhance flexibility.

Dreaming in Cubes

Minecraft features infinite replayability due to its sophisticated world generation mechanics, which use noise functions to create expansive worlds divided into chunks of 16×16×384. An alternative approach called ChunkGAN has been developed for similar world generation challenges. A video by Lewis Stuart from January 2026 discusses the difficulties of 3D generative modeling, particularly the lack of quality 3D datasets and the complexities introduced by the third dimension. The video emphasizes issues related to diffusion models that require labeled data and the challenges posed by scale, such as a repository of 512×512. The training data for this research was generated by the author using Minecraft Java Edition, with chunks extracted through a custom script, ensuring no third-party datasets were used.

Government has carried out no modelling on under-16 social media ban impacts

Campaigners are urging caution regarding a proposed ban on social media for individuals under 16, as the Department for Science, Innovation and Technology (DSIT) has not conducted any internal modeling or analysis to assess the potential impacts of such a ban. The DSIT acknowledged that "clear, agreed evidence does not currently exist" in response to a Freedom of Information request. In legislative discussions, MPs rejected immediate restrictions on social media for minors, while Sir Keir Starmer emphasized the need for action without guaranteeing prompt implementation. The government is piloting measures such as app bans, time restrictions, and overnight curfews with approximately 300 teenagers involved in a trial. Research led by Professor Amy Orben indicates gaps in understanding the relationship between children's mental health and digital technology use, highlighting the need for high-quality studies. The DSIT confirmed it has internal research on the subject but is withholding it to avoid misinterpretation. Burrows advocates for stronger regulation targeting online harm instead of outright bans, suggesting bans may not effectively address safety concerns. A DSIT spokesperson reiterated the commitment to building a strong evidence base and seeking public input before making decisions.

TotalAV Keeps Prices Low While Covering the Basics of Online Protection

TotalAV, founded in 2016, offers a competitive antivirus solution with an entry-level plan aimed at users seeking essential coverage at a reasonable price. Its features include real-time malware scanning, a browser extension called WebShield for blocking dangerous links, a system cleanup tool, and a basic password vault. The Android app is user-friendly, while the iOS version provides limited features due to Apple's restrictions. TotalAV includes a VPN with a daily data cap and effective phishing protection through its WebShield feature. Renewal costs can increase significantly after the first year, and independent lab testing of TotalAV is less frequent compared to competitors like Bitdefender and Kaspersky.

Android 17 Beta 4 arrives with post-quantum cryptography and new memory limits

On April 16, Google released Android 17 Beta 4, concluding its beta phase and focusing on app compatibility and platform stability. Developers must finalize updates for Android 17 to avoid delays when the stable version is released. Key behavioral changes for apps targeting Android 17 include: - Large-screen resizability restrictions, preventing apps from opting out of maintaining orientation, resizability, and aspect ratio constraints. - Expanded restrictions on dynamic code loading, requiring native files loaded via System.load() to be read-only. - Certificate Transparency is enabled by default. - Local network access is restricted by default, with a new ACCESSLOCALNETWORK permission for persistent access. - Stricter rules on background audio interactions, including playback and volume change APIs. Android 17 introduces per-app memory limits based on device RAM to target memory leaks and anomalies, with minimal impact expected on app sessions. Developers can check for memory limit impacts via ApplicationExitInfo and utilize profiling tools in Android Studio Panda. An on-device anomaly detection service monitors resource-intensive behaviors and provides profiling artifacts. Additionally, the Android Keystore now supports ML-DSA for quantum-safe signatures, allowing developers to generate keys and create signatures within secure hardware.
