Windows Update KB5077241 February 2026 Issues Nvidia GPU Bugs Task Manager Errors and ViVeTool Guide

Windows Update KB5077241, released in February 2026, is a 4.5GB feature update for the 24H2 and 25H2 versions. It poses significant performance risks for older hardware, particularly laptops and desktops without a Neural Processing Unit (NPU). Users with outdated Nvidia graphics cards, specifically the 900 Series (Maxwell) and 1000 Series (Pascal), report issues such as game stuttering, screen flickering, and system boot failures. The update also contains a flaw that inaccurately displays CPU usage in Task Manager, showing 0% utilization even under load. Many users face installation issues, encountering Error 0x800F0983, requiring them to delete update cache files and run repair tools. The update introduces features like a Taskbar Speed Test, Sysmon Security, improved Sleep/Wake functionality, and WebP wallpaper support, but many remain locked. Users can enable these features using ViVeTool with specific commands. Overall, the update is advised against for those with older Nvidia GPUs due to potential conflicts and performance issues.

Don’t Make These Mistakes After Updating Your Android Phone

Keeping system software on Android devices updated is essential for security, bug fixes, and performance improvements. After a significant update, users should review device settings as some may revert to defaults. Clearing the device's system cache and rebooting is recommended to optimize performance, as temporary files can accumulate during updates. To clear the cache, access the Android Recovery menu and select "Wipe Cache Partition." Following an update, it's also important to check for individual app updates in the Google Play Store. Users should verify available storage, as updates can consume significant space, and maintaining at least 10% free storage is advised. If issues persist, rebooting the device in safe mode can help diagnose problems by disabling extra apps and widgets.

How OpenAI Scaled to 800 Million Users on PostgreSQL

OpenAI has scaled PostgreSQL to support over 800 million active users of ChatGPT, making it one of the largest PostgreSQL deployments globally. The database can handle millions of concurrent connections and a very high volume of requests per second. OpenAI employs several strategies to optimize performance: 1. **Connection Pooling with PgBouncer**: Reduced database connections from 10,000 to 200, enhancing efficiency by a factor of 50. 2. **Read Replicas**: Distributes read requests across multiple replicas while the primary database handles writes. 3. **Horizontal Sharding**: Partitions data across multiple instances based on a shard key, such as user_id or tenant_id. 4. **Query Optimization**: Analyzes slow queries and creates appropriate indexes to maintain performance. 5. **Connection Management**: Implements timeouts and connection limits to prevent overload. 6. **Caching**: Uses application-level caching with Redis to reduce database load. 7. **Monitoring and Observability**: Tracks key metrics like connection counts and query latency to identify issues early. These strategies enable OpenAI to maintain performance and reliability for a large user base.

I’m stuck with Windows for gaming in 2026, but here’s how I’m optimizing it

In early 2026, Windows 11 posed challenges for users, leading to multiple reinstallations. To optimize gaming performance, users can create a restore point, activate Game Mode, adjust power settings to High Performance or Ultimate Performance, enable "Optimizations for windowed games," and activate Hardware-accelerated GPU scheduling. Managing startup apps through Windows Settings or Task Manager, disabling the Virtual Machine Platform and Hyper-V, and using the Win11Debloat PowerShell script can improve system performance. Adjustments in the NVIDIA Control Panel, such as setting the Shader Cache Size to 10 GB and Power management mode to "Prefer maximum performance," enhance gaming experience. Registry edits like changing Scheduling Category to High and modifying NetworkThrottlingIndex can further optimize performance.

OpenAI Scales Single Primary Postgresql to Millions of Queries per Second for ChatGPT

OpenAI scaled PostgreSQL to handle millions of queries per second for its ChatGPT service and API, serving 800 million users. Collaborating with Azure, they optimized deployment on Azure Database for PostgreSQL, maintaining a single-primary instance with nearly 50 geo-distributed read replicas to manage read operations and keep latency low. Key optimizations included increasing instance size, refining query patterns, and directing write-heavy workloads to sharded systems like Azure Cosmos DB. OpenAI faced operational challenges such as cache-miss storms and complex multi-table joins, which they addressed by shifting tasks to the application layer, enforcing stricter timeouts, and refining query structures. They reduced write pressure on PostgreSQL by migrating shardable workloads, implementing rate-limiting, and utilizing connection pooling with PgBouncer. Future strategies include exploring cascading replication to alleviate the primary instance's load and assessing sharded PostgreSQL deployments to enhance scalability while balancing consistency and performance.

Instagram app crashing within seconds of opening on Android for many [U: Widespread again]

The Instagram app for Android is experiencing significant crashing issues, particularly related to beta version 417.0.0.0.73, causing frustration among users who report the app force-closing within seconds of launching. Problems began two days ago with crashes when liking comments and escalated to the app failing to launch. Users have encountered the error message “Something went wrong with Instagram” and have reported their photo grids disappearing, despite everything being intact on the web version. Clearing the cache provides only temporary relief, and standard troubleshooting methods have not resolved the issues. Many users are unable to disable the Early Access toggle due to errors. Meta has not yet acknowledged these problems publicly. Some users are considering installing an older APK file as a temporary solution.
