Microsoft once used its own brand of ‘Lego’ to optimize Windows

Former Microsoft engineer Dave Plummer reflected on software performance challenges during the '90s, specifically the limitations of machines with 12 MB of RAM. He discussed the Basic Block Tool (BBT), which optimized software binaries by reorganizing their structures to enhance execution speed. A typical binary contained around 10 MB of code, but only about 300 KB was necessary for startup. If this essential code was scattered, it led to performance degradation due to excessive page access. BBT defragmented binaries, grouping related code to streamline access and improve user experience, particularly for large products like Windows and Office. Modern tools like BOLT and HP's Dynamo continue to optimize binary layouts and runtime code, but Plummer cautioned about the risks of manipulating binaries. He noted that while computational power has increased, modern software faces similar performance challenges, with larger binaries and complex dependency graphs. He emphasized the importance of locality in software design, advising to keep hot data and code together to enhance performance.

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.

Microsoft is killing every ancient Windows 11 dialog box with a modern rewrite, and file copy is already done

Microsoft is redesigning legacy dialog boxes in Windows 11, moving towards modern WinUI 3 interfaces. The company has begun implementing dark mode for some legacy dialogs, starting with file operation dialogs. A WinUI 3-based redesign of the Windows Run dialog is planned as an optional feature. March Rogers, Partner Director of Design at Microsoft, confirmed that a comprehensive redesign is underway, with the file copy dialog already completed and the common file dialog in progress. Users have expressed the need for more extensive updates to various legacy dialogs, and Microsoft is considering releasing these modern versions as optional features.

How to Use Android Storage Tools Like Google Files App to Free Up Space and Improve Android Performance

As Android phones accumulate data, users may experience performance declines due to filled internal storage from photos, videos, cached files, downloads, and unused applications. Performance issues can include slower app launches, lag during multitasking, delayed software updates, camera saving issues, and reduced gaming performance. Regular storage management is essential for optimal device performance. Android devices come with built-in storage management tools such as the Google Files app, Google Photos "Free Up Space," Smart Storage, cache management settings, and app archiving features. These tools are generally safer than third-party cleaning applications. The Google Files app scans devices and suggests safely removable files, detecting duplicates, large videos, old screenshots, temporary files, unused downloads, and blurry images. Users can access cleanup suggestions by opening the app, tapping the "Clean" tab, reviewing suggestions, selecting unwanted files, and confirming deletion. The app also features a Trash option for temporarily holding deleted files. Google Photos allows users to remove local copies of backed-up files by tapping the profile icon, selecting "Free up space," reviewing backed-up files, and confirming deletion. Users can choose between "Storage Saver" and "Original Quality" backup settings. Smart Storage automatically deletes backed-up photos and videos when storage is low. Clearing cache can improve performance by removing accumulated temporary files. Users can clear cache by going to Settings, tapping Apps, choosing an app, selecting Storage, and tapping "Clear Cache." Removing unused applications can free up space and improve system organization. Common mistakes include installing untrustworthy third-party apps, deleting files without backups, clearing app data instead of cache, and neglecting large downloads and duplicates. Simple habits like deleting old screenshots, regularly clearing downloads, backing up photos, monitoring storage monthly, and limiting offline video downloads can improve storage management.

Windows on ARM Security: How to Protect ARM-Based Windows Devices Without Gaps

The transition to Windows on ARM devices is increasing across various sectors, with organizations drawn to their performance, efficiency, and battery life. However, there are concerns about securing these devices without introducing vulnerabilities. Windows on ARM security involves safeguarding ARM64-based Windows devices with endpoint security solutions optimized for ARM architecture. The lack of native ARM64 endpoint protection can leave devices vulnerable. Windows on ARM devices operate on ARM64 architecture, differing from traditional x86/x64 systems, which can lead to incomplete protection, performance issues, and compatibility challenges with legacy security tools. This creates security gaps, making ARM-based devices attractive targets for threats like ransomware. To secure ARM-based Windows endpoints effectively, organizations need native ARM64 endpoint protection that ensures optimal performance, consistent protection across all devices, and centralized policy management. Morphisec offers native ARM64 endpoint protection, focusing on preventing threats before execution and providing seamless deployment and management. Without native support, organizations risk fragmented security tools, an expanded attack surface, and operational inefficiencies. Implementing native ARM64 endpoint protection allows for standardized security, simplified processes, and enhanced resilience against advanced threats.

Android Apps on Windows 11: Safe Alternatives After WSA

In 2025, Microsoft announced it would discontinue support for the Windows Subsystem for Android (WSA), making Android applications non-functional on Windows 11. This decision surprised many users in Indonesia who relied on these applications. HP developed a guide outlining secure alternatives to WSA, which included reputable Android emulators like BlueStacks, LDPlayer, and NoxPlayer, as well as native Windows alternatives such as Microsoft Teams and Microsoft 365 apps. Users were advised against unverified APK sideloading, unofficial emulators, and modified apps due to security risks. Microsoft’s end of support means no further security updates or bug fixes will be provided, and integration with the Amazon Appstore will cease. Users can continue using WSA apps, but they will be exposed to potential security threats. To migrate data from WSA, users were instructed to inventory apps, research alternatives, and export app data before performing a clean uninstall. Best practices for running Android apps safely on Windows included downloading from official sources and keeping software updated.
