This update enhances reliability in File Explorer and improves common issues like sleep resume times and printing performance. The new Sysmon feature allows administrators to capture system events directly within the OS without needing third-party tools, although it remains disabled by default. Additionally, users can now set WebP images as desktop backgrounds, and the taskbar now displays search group headers with result counts for easier navigation

Microsoft has released a preview update for Windows 11 26H1 that delivers some genuinely useful tools instead of just another list of minor bug fixes. Power users will appreciate the native System Monitor functionality now built directly into the OS to capture system events without relying on third-party tools from Sysinternals. The taskbar gains a quick network speed test and File Explorer improves reliability when opening new windows or extracting non-ZIP archives during heavy usage. Quality of life tweaks include setting WebP images as backgrounds and fixing sleep resume times so the PC wakes up faster after sitting idle.
