When Microsoft was developing Windows 95, developers discovered that SimCity had a severe memory bug that caused it to crash on the new operating system—but instead of forcing the game studio to fix it, Microsoft engineers actually rewrote the core Windows 95 source code to detect if SimCity was running and safely allocate memory for it.

Windows 95 contains a block of code that checks if the user is playing SimCity and adjusts memory management to address a bug from the game's programming. This bug, a "use-after-free" error introduced by SimCity's developer Jon Ross, went unnoticed in Windows 3.x but caused crashes in Windows 95 due to its different memory management. Instead of asking Maxis to fix the bug, Microsoft engineers modified Windows 95 to mimic the older memory behavior, ensuring SimCity would run smoothly. This approach reflects Microsoft's broader strategy of maintaining compatibility with older software through various "shims," allowing legacy programs to function on modern systems.

Microsoft says you should pause Windows 11 Updates when you need to work, as it tests greater controller

Microsoft is shifting its approach to Windows updates, responding to user frustrations about receiving update notifications during critical work hours. The company is currently testing more nuanced controls for updates with Windows Insiders, including a "Pick a date" feature that allows users to pause updates for up to 35 days, with the option to extend the pause indefinitely. Retail Windows 11 users can pause updates for up to five weeks, after which updates will automatically download without further pause options. Microsoft acknowledges that the frequency of updates can disrupt workflows for its 1.6 billion users, many of whom view mandatory updates as interruptions. The time required for updates has increased due to larger cumulative update packages, which can exceed 4GB, and the complexity of the operating system. To improve user control, Microsoft is testing a new power menu that separates update and shutdown options, allowing users to power down without installing updates. Additionally, updates will now include device class information in their titles for better user awareness. These changes aim to streamline the update experience and address long-standing user complaints.

I investigated Windows 11’s massive 5GB monthly .msu updates. AI is only part of the problem.

Windows 11 updates have significantly increased in size, with monthly cumulative updates often exceeding 4GB and some approaching 5GB. One update can expand to nearly 9GB when extracted. Microsoft has shifted to delivering Latest Cumulative Updates (LCUs), which include all previous fixes, leading to larger update sizes over time. The introduction of Checkpoint Cumulative Updates aims to reduce this growth by establishing periodic baselines, but the effectiveness has been mixed. The May 2025 cumulative update saw a size increase from approximately 6.5GB to nearly 9GB, with new MSIX files related to semantic search and on-device AI contributing to this growth. Windows Update uses applicability logic to minimize download sizes for users, but enterprises must download full packages, resulting in increased storage costs. The average yearly storage cost for enterprises rose from about 11 GB in 2024 to 52 GB by 2026. Users can check their actual download sizes through the Windows Update settings and Event Viewer logs.

Microsoft confirms old Windows 8 UI elements are being replaced in Windows 11, but there is more work to be done

Microsoft is updating the input method switcher on the Windows 11 login screen to align with the operating system's modern design, responding to user feedback about its outdated appearance. The input switcher, which has a rigid, square design, contrasts with the rounded aesthetics of Windows 11. Other legacy UI elements from Windows 8 and earlier versions, such as the Windows Recovery Environment and the Control Panel, remain present in the system. Microsoft is gradually migrating functionalities from the Control Panel to the Settings app, but inconsistencies persist in various system tools like File Explorer, the Run dialog, Registry Editor, and Device Manager. The company is actively addressing these legacy UI issues to enhance the user experience and achieve a more unified design language in Windows 11.

Microsoft tells crusty old kernel drivers to get with the Windows Hardware Compatibility Program

Microsoft is enhancing the security of the Windows kernel by eliminating trust for kernel drivers not certified through the Windows Hardware Compatibility Program (WHCP) starting with the April 2026 Windows Update. This change specifically targets kernel drivers signed by the now-obsolete cross-signed root program, which has been associated with security vulnerabilities. The new policy will initially be introduced in an "evaluation mode" to monitor and audit driver loads for potential compatibility issues. Custom kernel drivers can still be used under the Application Control for Business policy, but must be signed by an authority within the device's Secure Boot Platform Key or Key Exchange Key variables. The changes will impact Windows 11 versions 24H2, 25H2, 26H1, and Windows Server 2025.

Windows 95 let installers trash its files then fixed the mess behind their backs

Microsoft veteran Raymond Chen discussed how Windows 95 handled installers that overwrote crucial system files. The operating system was designed to allow installers to compare version numbers, permitting overwrites only if the new file had a higher version. However, many installers ignored this rule, often replacing Windows 95 components with outdated Windows 3.1 versions, causing significant system issues. Windows 95's commitment to backward compatibility meant that preventing file operations could disrupt installers, leading to installation failures or error messages for users. To address these challenges, Microsoft created a hidden directory, c:windowssysbckup, to store commonly overwritten files. After an installation, Windows would check version numbers and replace lower versions with higher ones, maintaining system integrity despite third-party installer chaos.

Xbox Project Helix Specs Leak: Why Microsoft’s New Console is Amazing

Microsoft's gaming console, codenamed Project Helix, integrates console and PC ecosystems, featuring a custom AMD System on Chip (SoC) with a 3nm process, and a GPU based on AMD's RDNA 5 architecture. It reportedly rivals Nvidia’s RTX 5080 in rasterization and outperforms the RTX 5090 in ray tracing. The console includes a dedicated Neural Processing Unit (NPU) for enhanced AI capabilities, supporting both Xbox and PC games natively. It utilizes AMD’s FSR Diamond technology for near-native 4K visuals and incorporates DirectStorage technology for faster load times. Project Helix supports four generations of Xbox games and is expected to have alpha development kits available in early 2027, with a consumer launch in 2028, priced between ,000 and ,200.

X1 Box App Brings Classic Xbox Games To Android, But There’s A Caveat

X1 Box is an Xbox emulator available on Android for .99 through the Google Play Store. It is a fork of the open-source Xemu emulator, with its source code publicly available on GitHub. The decision to monetize X1 Box without compensating the original developers has raised ethical concerns. The Xemu team is developing their own dedicated Android version. Performance evaluations indicate that X1 Box has inconsistent performance, often capped at 30 frames per second, which affects gameplay.

Making music with MIDI just got a real boost in Windows 11

MIDI serves as a crucial tool for musicians, enabling instrument synchronization, effects control, and electronic music creation. It began at the 1983 NAMM Show with the introduction of MIDI 1.0, which transmitted messages over a DIN serial cable. MIDI 1.0 has limitations, such as a control parameter range of 0-127 and inadequate support for orchestral articulation. In 2020, MIDI 2.0 was introduced, offering improvements like bidirectional communication, automatic device discovery, and high-resolution controllers. Windows 11 now supports both MIDI 1.0 and MIDI 2.0 through Windows MIDI Services, which includes features like multi-client support, customizable MIDI endpoints, built-in loopback, and tighter message timing. A new USB MIDI 2.0 class driver has been developed, and tools for MIDI scripting will be released soon. The development of Windows MIDI Services involved community collaboration, and future enhancements are planned for music creation on Windows.
