Windows 11 February preview adds Sysmon, network speed test, and BitLocker improvements
Microsoft released the Windows 11 KB5077241 optional preview with 29 changes: improved BitLocker reliability; built-in network speed test for Ethernet, Wi‑Fi, and cellular; native Sysmon support (off by default) and auto Quick Machine Recovery on eligible Pro devices; plus UI and reliability tweaks (faster wake from sleep, smarter taskbar overflow, WebP desktop backgrounds, and RSAT on Arm64). It’s a non-security preview that can be installed via Settings > Windows Update or the Microsoft Update Catalog.
