Why I stopped using ‘Modern Standby’ on my Windows laptop to save battery overnight

Many newer PCs support a feature called Modern Standby, which allows minimal background processes to continue running during sleep mode, leading to quicker wake-up times but potentially less efficient battery preservation. PCs can operate in one of six states, with S0 indicating full operation and S5 indicating a complete shutdown. Modern Standby (S0 Low Power Idle) turns off the display and most core components while allowing limited background activity, which may vary in effectiveness for battery drain. Traditional Sleep (S3) shuts down the screen and main components but may take longer to resume. Hibernate (S4) saves the current session and powers off completely, while Restart clears memory and resets the operating system. Shut Down (S5) clears memory and terminates processes, using a "soft off" method that retains certain settings for quicker startups through fast boot. Disabling fast boot can be done via the Control Panel. Although Modern Standby can conserve battery, it may not always be effective, as issues with firmware or drivers can prevent the computer from entering a true low-power state. For maximum battery efficiency, using the Shut Down option is recommended, especially with fast boot enabled for quick startups.

Researchers find 50 ‘dangerous’ Android apps that are secretly hijacking phones: Who is at risk

Recent findings from McAfee have revealed a malware campaign named Operation NoVoice that has infiltrated over 50 applications on the Google Play Store, which collectively received over 2.3 million downloads before being removed. The malware uses a rootkit attack strategy to gain administrator-level control of Android devices while remaining undetected. Affected apps appeared benign, performing tasks like cleaning files or managing photos, but were secretly communicating with a remote server to send device information. This allowed attackers to deploy custom exploit code, achieving root-level access and posing significant security risks. The malware persists even after factory resets, potentially requiring firmware reinstallation for complete removal. Users with older or unpatched Android versions are at greater risk, as well as anyone who downloaded the compromised apps.

How to Profile Modern PC Games with NVIDIA Nsight Graphics

Performance analysis in PC gaming has become more complex with the introduction of DirectX 12 and Vulkan, incorporating technologies like asynchronous compute, hardware ray tracing, and machine learning-assisted denoising. Understanding GPU performance requires advanced tools to analyze workload distribution and shader behavior, with NVIDIA Nsight Graphics being a key resource. NVIDIA Nsight Graphics is a graphics debugger and profiler for modern graphics APIs, featuring the GPU Trace Profiler, which provides detailed insights into GPU execution and performance bottlenecks. Recent updates have improved its utility, including a Flame Graph for the Shader Profiler and support for NVIDIA's DLSS in D3D12 applications. The Peak-Performance-Percentage analysis method focuses on identifying GPU workload constraints and optimizing utilization rather than relying on assumptions about performance bottlenecks. This methodology is applied using Nsight Graphics to analyze GPU traces from the game Cyberpunk 2077, contrasting traditional rasterization with path tracing enhanced by DLSS Ray Reconstruction. The test setup included an Intel Core i7-14700K CPU, 32 GB RAM, and an NVIDIA GeForce RTX 4090 GPU, capturing two scenarios: one with raster-only settings and another with path tracing and DLSS. The analysis revealed that the rasterized frame's most costly aspect was lighting processing, while the path-traced frame showed increased total frame cost and a hybrid workload involving rasterization, ray traversal, and AI-driven processes. Key findings indicated that modern GPU performance is heavily influenced by memory behavior rather than just shader arithmetic, with significant time spent on compute-driven lighting processing and data movement. The analysis also highlighted that ray tracing performance is constrained by memory efficiency, indicating that performance does not scale linearly with RT-core throughput.

Windows Security App Gains Secure Boot Certificate Status Ahead of Major Certificate Refresh

The Secure Boot certificates used by the Unified Extensible Firmware Interface (UEFI) on Windows PCs will expire in late June 2026. Microsoft is rolling out updated certificates through Windows Update to ensure user protection. Starting in April 2026, users can check their device's status in the Windows Security app, which will feature a color-coded badge system: - Green Checkmark: New certificates are installed, no action needed. - Yellow Caution Badge: Update pending or blocked due to hardware/firmware issues (expected in May 2026). - Red Stop Icon: Alerts users that older certificates are expiring, potentially preventing essential boot-level security updates (may appear as early as June 2026). The status will also be indicated in the Windows Security system tray icon. Most users will have a seamless update process by keeping Windows Update enabled, with devices from 2025 and many from 2024 covered. Older machines will receive updates gradually, guided by major OEMs. Microsoft advises against ignoring yellow or red warnings, as devices without updated certificates may be vulnerable to security threats and incompatible with future Windows updates. A support resource is available at aka.ms/getsecureboot.

How to use and deploy Android Work Profile in your business

The mobile device has become a dual-purpose tool for personal and professional needs, enhancing productivity but also introducing security challenges for organizations with bring-your-own-device (BYOD) policies. Samsung addresses these challenges with its Android Work Profile feature, which separates business applications and data from personal content on devices like the Galaxy S26 Series, Galaxy Z Fold7, and Galaxy Z Flip7. Android Work Profile creates two isolated profiles on a single device, allowing IT teams to manage corporate applications while keeping personal information private. IT administrators can monitor work profile applications and data but cannot access personal profiles, ensuring employee privacy. Employees can easily switch between work and personal applications and activate a “pause work apps” feature during off-hours. To set up Android Work Profile, organizations need an Enterprise Mobility Management (EMM) solution and the Android Device Policy app. The Samsung Knox Suite provides tools for managing and securing devices, including Knox Mobile Enrollment and Knox Attestation. Android Work Profile benefits businesses by enhancing data security and reputation while promoting work-life balance for employees.

Microsoft’s Secure Boot certificates expire in June 2026, but older PCs may never get the fix

Every Secure Boot-enabled Windows PC relies on cryptographic certificates issued by Microsoft in 2011, embedded in the motherboard's firmware, to ensure a secure boot process. The first of these certificates will expire on June 24, 2026, which will affect the ability to receive future security updates for critical components of the Windows startup process. Microsoft is rolling out replacement certificates through Windows Update, marking a significant security maintenance effort. Secure Boot operates as a chain of trust with certificates stored in the motherboard's UEFI firmware, validating software before the operating system loads. The Platform Key (PK) is at the top of this chain, followed by the Key Exchange Key (KEK) and the Signature Database (DB). The replacement certificates introduced in 2023 restructure certificate management, separating responsibilities among different certificate authorities to enhance the trust model. Not all PCs are affected by the upcoming expiration; newer devices manufactured since 2024 already have the new certificates. Windows 10 users face challenges as support for this version ends in October 2025, and they will not receive the new certificates unless enrolled in Extended Security Updates. Home users should ensure their PCs are set to receive updates automatically, while enterprise environments require coordination for firmware updates before the Windows certificate update.
