Windows 10 is more stable than Windows 11 in 2026, data shows

The September update for Windows 11 caused significant disruptions, including failures in USB audio functionality and the File History feature. This follows a trend of issues over the past months, with August experiencing printer and PDF problems, July affecting certain Dell PCs, and June reporting startup issues and BitLocker recovery failures. In total, eight out of nine months this year have had at least one major issue. A recurring BitLocker user lockout problem has also been noted. Despite these issues, Windows 11 has improved in overall stability, with fewer system crashes. Windows 10 has maintained stability by focusing solely on security updates since support ended in October 2025, avoiding new feature rollouts. Users satisfied with Windows 10's features may prefer to stay with it for stability. Windows 11 users facing instability can roll back updates or use the Known Issue Rollback feature to revert problematic non-security features.

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.

ValleyRAT Backdoor Hides in Signed Adware That Users Add to Antivirus Exclusions

Silver Fox is linked to the distribution of a backdoor malware called ValleyRAT, disguised as the legitimate QN Wallpaper adware application. Once installed, ValleyRAT provides complete control over the compromised machine. The malware uses DLL sideloading to operate under the guise of a legitimate process, bypassing security measures. It disables Windows Defender and adds itself to autorun entries, and can mark its process as critical, causing system crashes if terminated. Kaspersky has identified specific indicators of compromise (IoCs) including hashes, command-and-control servers, and associated domains. In 2026, Kaspersky recorded over 100,000 detections of ValleyRAT affecting more than 1,500 unique users, mainly in China and India.

Windows 11 shut down controls for your PC may soon be available on your smartphone

The Link to Windows smartphone app may introduce remote shutdown capabilities for PCs, as indicated by recent data mining of its Android APK. A component called ‘RemoteControlManager’ has been found in the app's debug log, suggesting potential functions like restart, sleep, and shutdown options. The app is also expected to monitor system updates. However, warnings about potential data loss during shutdowns or restarts are present, and the current build lacks detailed notifications for affected applications. Users can choose to put their systems to sleep to avoid data loss, but this limits smartphone interaction until the PC is awakened. It is unclear when Microsoft will activate these features.
