Highlights for the Windows 11, version 25H2 update:
The Emoji 16.0 release introduces a small, thoughtfully curated set of new emojis, one from each major category. Each emoji carries timeless symbolism and practical versatility. These new emojis now appear in the emoji panel.
A built‑in network speed test is now available from the taskbar. You can open it from the Wi‑Fi or Cellular Quick Settings, or by right-clicking the network icon in the system tray. The speed test opens in the default browser and measures Ethernet, Wi‑Fi, and cellular connections.
You can now control pan and tilt for supported cameras in the Settings app. The controls appear under Settings > Bluetooth & devices > Cameras, in the "Basic settings" section for your selected camera.
Windows now brings System Monitor (Sysmon) functionality natively to Windows. Sysmon helps you capture system events for threat detection, and you can use custom configuration files to filter the events you want to monitor. Windows writes captured events to Windows Event Log, which allows security tools and other applications to use them.
