Windows 11 26H2 gave my laptop nearly 2GB of RAM back, but there’s a catch for low-RAM PCs

Windows 11 version 26H2 has been released, resulting in a decrease in RAM usage for many users. Reports indicate that users with 16GB or more of RAM have experienced reductions in idle memory usage, with one user noting a drop from 6.9GB to approximately 4.8GB, and another from over 10GB to about 7GB. However, users with 8GB of RAM have not reported similar improvements, leading to concerns that this update primarily benefits those with larger memory capacities. Personal tests on a laptop showed a decrease in idle memory usage from 8.5GB to 6.7GB after the update. Despite Microsoft's commitment to optimizing memory usage, the 8GB machines have not seen the same enhancements.

Microsoft shares simple yet overlooked tip to help fix your slow Windows 11 PC

Microsoft is addressing the memory-intensive nature of Windows 11 and has announced new performance tools to optimize the operating system. Users can manage startup applications to reduce system slowdowns by disabling unnecessary apps that launch at boot-up, which can improve boot times and conserve CPU and memory resources. This can also enhance battery performance on mobile devices. Users can access Task Manager to see the "Startup impact" of each application, categorized as Low, Medium, or High impact based on resource usage during startup. Caution is advised when disabling High impact programs, as some may be essential. Users can also manually add applications to the startup sequence and apply settings across multiple user accounts using the common startup folder.

You should deep clean your Windows PC every year to keep it running smoothly — here’s how I do it

Maintaining the performance of a Windows 11 computer requires regular care, particularly in software management. An annual deep clean is recommended, with the following steps to improve performance: 1. Uninstall Apps: Use BCUninstaller to remove unnecessary applications, including those from the Microsoft Store, with a bulk uninstall feature and a post-uninstallation cleanup for leftover files. 2. Run a Debloat Script: Utilize tools like Chris Titus Tech's Windows Utility to disable unnecessary bloatware and manage telemetry settings. 3. Disable Startup Apps: Access the Task Manager to disable non-essential applications that launch at startup, improving boot times. 4. Check for Driver Updates: Ensure drivers are up to date through Windows Update and check graphics driver websites for the latest versions. 5. Run a Malware Scan: Use Malwarebytes for deep scans to identify and remove potential malware threats. 6. Delete Temporary Files: Clear temporary files through the Settings app and clean up web browser cached files to free up space.

Windows devs rerolled old code to save precious bytes

Veteran Microsoft engineer Raymond Chen shared a story about the development of an x86-32 emulator that utilized binary translation, significantly improving performance compared to traditional emulation methods. During the project, the team faced an issue where a function allocated 64 KB of memory but was optimized by a compiler into 65,536 instructions, leading to 256 kilobytes of code being used to initialize the data. In response to this inefficiency, the engineers modified the translator to replace the inefficient function with a more compact loop, highlighting their commitment to memory efficiency during a time when operating systems prioritized resource conservation.

Avast Antivirus in 2026: Still Worth Paying For on Windows and Mac?

Ransomware is evolving, and many users in the United States continue to invest in Avast Antivirus as of 2026. Avast, now part of Gen Digital, has shifted from a traditional free antivirus to a comprehensive consumer security suite, which includes three tiers: Avast Free Antivirus, Avast Premium Security, and Avast One. The product lineup features a core antivirus engine, ransomware and phishing protection, a firewall, Wi-Fi inspector, built-in VPN, and performance cleanup tools. Avast's core antivirus engine provides real-time file scanning and web/email shields, consistently ranking high in independent lab tests for malware protection. The ransomware shield protects sensitive folders from unauthorized encryption, while the firewall and Wi-Fi inspector are available in paid tiers. The built-in VPN is designed for safer public Wi-Fi use, and performance tools aim to optimize system efficiency. Pricing for Avast products in the US varies, with a free tier supported by upsell prompts for premium features, Premium Security typically offered as an annual subscription, and Avast One marketed as a higher-value bundle. Renewal pricing often increases significantly after the first year, leading to user complaints. Microsoft Defender is now effective enough that many experts believe average users may not need third-party antivirus software, but Avast justifies its subscription by offering stronger web protection, more control over app permissions, and additional non-security features. User feedback highlights strong protection but frequent upsell prompts, performance issues on low-end machines, and concerns over past data collection practices. Avast is seen as valuable for households with mixed tech literacy, remote workers, students on older hardware, and users seeking basic privacy protections.

Windows 11 Trails Older OS Versions in ThinkPad X220 Speed Tests

Windows 11 has been tested on a Lenovo ThinkPad X220, revealing it to perform poorly compared to its predecessors, particularly Windows 8.1, which excelled in benchmarks for boot times and application launches. The test involved various Windows versions (XP, Vista, 7, 8.1, 10, and 11) on the same aging hardware, highlighting that Windows 11 consistently finished last in most categories. The ThinkPad X220 does not meet Windows 11’s minimum requirements, lacking essential components like TPM 2.0 and a compatible processor, which may have skewed the results. Critics argue that using outdated hardware for testing is not representative, suggesting that a fair comparison would involve flagship devices from each generation. Windows 11's architecture is designed for modern multicore CPUs and SSDs, which may struggle on older hardware. Additionally, Windows 11 has heavier overheads due to advanced security features, which consume resources that older operating systems do not. User feedback indicates frustration with Windows 11's performance on legacy hardware compared to leaner alternatives like Linux. Despite Microsoft promoting optimizations in Windows 11, these did not manifest in the ThinkPad test, and the findings raise concerns for businesses considering upgrades as Windows 10 approaches its end-of-support date in 2025.
