Windows 11 may have just kickstarted 2025’s biggest comeback story

Windows 11 has reached a market share of 36.65% among Windows desktop users, the highest since its launch on October 5, 2021. In contrast, Windows 10 holds a 60.33% share. The increase in Windows 11 adoption is attributed to new purchases during the holiday season, with historical data showing growth from 16.97% to 18.12% between December 2022 and January 2023, and from 26.54% to 27.83% between December 2023 and January 2024. Despite fluctuations in user numbers throughout 2024, it is expected that Windows 11's market share will continue to rise, especially with the end-of-support for Windows 10 approaching on October 14. Windows 10 users will lose access to critical security updates and technical support after October 2025 unless they pay for Microsoft's Extended Security Updates. Additionally, potential increases in hardware prices may prompt users to upgrade to meet Windows 11's requirements.

TotalAV Free Edition

TotalAV Free Edition provides limited antivirus protection, relying heavily on Microsoft Defender for real-time scanning. Installation is straightforward but can be lengthy, and users are automatically enrolled in a seven-day trial of TotalAV Antivirus Pro. The interface resembles the premium version, but it lacks real-time protection, leading to constant alerts for users to upgrade. Independent lab tests have shown that only the Pro version has been evaluated, achieving good scores, while the free edition remains untested. Users can perform on-demand or scheduled scans, with a full scan taking about 53 minutes. However, TotalAV does not register with Windows, complicating the user experience by requiring both TotalAV and Microsoft Defender to operate simultaneously. In a malware protection test, the free edition achieved a 99% removal rate of malware samples, but its phishing protection is inadequate, relying on Edge’s SmartScreen Filter, which has a low detection rate. Most privacy features are locked behind a paid upgrade, although it includes a clean-up scan and uninstaller feature. The Total Security page is the same for both editions, but most features require an upgrade. Overall, the free edition's reliance on Microsoft Defender and limited features suggest users might find better standalone antivirus options.

Don’t look now, but Macs are finally getting good for gaming

The evolution of gaming on Mac has progressed significantly, with notable improvements in performance, particularly with the introduction of the M-series chips. The Mac Studio M2 Ultra and the 16-inch MacBook Pro M3 Max have demonstrated impressive gaming capabilities, with the latter achieving nearly 90 frames per second in Baldur's Gate 3 and maintaining around 50 FPS at high graphics settings. Historical data shows a clear trajectory of improvement in gaming performance across different MacBook models, with the M3 Max able to run Shadow of the Tomb Raider at 120 FPS at 1200p resolution. Despite these advancements, MacBooks still face challenges compared to dedicated GPUs from competitors like AMD and Nvidia. Upcoming M4 MacBooks are expected to further narrow the performance gap with Windows laptops, particularly as some Windows devices struggle with compatibility issues.

No, generative AI isn’t going to take over your PC games | Digital Trends

A recent article from PC Gamer discussing generative AI in video games sparked controversy, with industry professionals criticizing its portrayal of AI-generated content. A character designer from Bioshock Infinite referred to an AI-generated reimagining of a character as “half-assed cosplay.” The article highlighted the distinction between generative AI, which creates outputs from inputs, and predictive AI, which forecasts outcomes. Nvidia’s projects, like RTX Remix, demonstrate practical applications of AI in enhancing game visuals without compromising creative integrity. AI tools like DLSS improve final outputs rather than generating them from scratch. Concerns about job displacement in the industry have arisen, particularly following layoffs among 2D artists at companies like Activision Blizzard. The discussion emphasizes the need for a balanced approach to AI in gaming, recognizing both its potential benefits and ethical implications.

PLN2 billion has been allocated for relief efforts, and expenditures related to the flooding will not be included in the European Commission's Excessive Deficit Procedure calculations. The European Commission will allow countries affected by the floods to reallocate up to €10 billion of EU funds, with Poland set to receive approximately €5 billion from Cohesion Funds. Proposed relief measures include direct aid for households up to PLN10,000, reconstruction assistance up to PLN200,000, mortgage relief through a bank-funded guarantee scheme, installment options for tax dues for companies, and agricultural tax reliefs for farmers.
