These 4 built-in Windows tools helped me build a self-healing PC

Windows operating systems include built-in tools for maintaining PCs, allowing users to monitor system health, repair corrupted files, and recover from boot failures with minimal intervention. Task Scheduler automates maintenance tasks by triggering them based on schedules or events, accessible via the Start menu or taskschd.msc. It can activate tasks at fixed intervals, on startup, during idle periods, or in response to Event Viewer entries. Tasks should run with the highest privileges and can be configured to execute regardless of user sign-in status. The Settings tab allows missed tasks to run as soon as possible. DISM (Deployment Image Servicing and Management) is a command-line utility that repairs the component store, essential for installing updates and restoring system files. It offers three inspection levels: CheckHealth, ScanHealth, and RestoreHealth, with the latter requiring an internet connection for downloading replacement files. DISM logs operations in C:WindowsLogsDISMdism.log. SFC (System File Checker) verifies and repairs core operating system files using Windows Resource Protection. The command sfc /scannow checks all protected files, while /verifyonly provides a report without changes. SFC's effectiveness depends on the integrity of the component store, making it essential to run DISM first. Results are logged in C:WindowsLogsCBSCBS.log. Quick Machine Recovery (QMR), introduced in Windows 11, addresses boot failures by connecting to the internet to find solutions when repeated boot failures are detected. QMR is enabled by default on unmanaged devices and can continuously check for fixes. It is designed to respond to widespread issues rather than unique problems and may not work effectively on older hardware or without a network connection. Together, these tools provide a comprehensive approach to system maintenance in Windows 11, ensuring the operating system remains healthy and efficient without additional software.

Microsoft just patched over 1,000 flaws in Windows, but you might want to wait to update your PC

Microsoft released a September Patch Tuesday update for Windows 11 that addressed nearly 1,000 vulnerabilities but introduced bugs affecting some users' PCs. The update, 25H2, reintroduced features like a movable taskbar and a customizable Start menu. Users with AMD Radeon GPUs reported system crashes due to driver instability, and emergency patches from Microsoft did not resolve these GPU issues. Users are advised to consider rolling back their systems to a state prior to the August Patch Tuesday. HP and Lenovo PC users are cautioned, as the update may cause BIOS corruption on HP machines and random shutdowns or black screens on Lenovo devices. HP is working on a BIOS revision, but the cause of the issues remains unclear.

Microsoft reveals why 32-bit Windows was limited to 4GB RAM, and it wasn’t a technical limit

32-bit Windows is commonly thought to be limited to 4GB of RAM due to its 32-bit address space, but this overlooks the role of Physical Address Extension (PAE), which allows access to more than 4GB of RAM on compatible processors. PAE enables 32-bit x86 processors to use 36-bit physical addresses. Windows allocates a 4GB virtual address space to each 32-bit application, with 2GB reserved for the application and 2GB for system use. Windows Server 2003 SP1 Enterprise can support up to 64GB of RAM, while the Datacenter edition can handle 128GB. Microsoft did not extend this capability to consumer editions due to the complexities and potential issues with hardware drivers, which often assume a 32-bit framework. Modifying drivers for PAE can be challenging, as incorrect assumptions about physical and virtual addresses can lead to memory corruption. To mitigate risks, Microsoft capped physical address space at 4GB in Windows XP SP2 and Windows Server 2003 SP1 Standard Edition. Server environments typically have more controlled hardware selections, allowing for the use of drivers that are tested for compatibility with addresses exceeding 4GB. Microsoft began discouraging the production of 32-bit systems in 2020 and ended 32-bit edition production with Windows 11.

Windows NT 4 went on sale 30 years ago today

Microsoft Windows NT 4.0 was officially released on August 24, 1996, marking its 30th anniversary today. Codenamed “Tukwila,” it integrated the Windows Explorer desktop from Windows 95 with the NT operating system. Windows 95 was released a year earlier on August 24, 1995, and was initially codenamed “Chicago.” Windows NT 4 incorporated a modern user interface while maintaining the reliability of the NT kernel. It introduced features like the journaling NTFS filesystem but had limitations such as stability issues due to changes in the Graphics Device Interface (GDI) and lack of support for FAT32 and USB interfaces. Despite these shortcomings, NT 4 was a significant operating system that contributed to the competitive landscape of operating systems.
