Microsoft's June 2023 Patch Tuesday brought Windows 11 KB5060829 (Build 22621.1848) as an optional preview update, delivering promised performance improvements alongside some stubborn bugs that continue to frustrate users. This cumulative update targets critical system components, with Microsoft's official changelog highlighting fixes for File Explorer, gaming performance, and multi-monitor setups.
