Side-by-Side Running: You can run both WSL 1 and WSL 2 distributions simultaneously on the same machine. Additional Notable Features
Cloud Download for Reset: When using the "Reset this PC" feature, you can now choose to download a fresh copy of Windows from the cloud instead of using the existing local files for a cleaner, more reliable recovery.
Renamable Virtual Desktops: You can finally give your virtual desktops custom names (e.g., "Work," "Gaming," or "Personal") rather than the default "Desktop 1" and "Desktop 2".
Task Manager Improvements: The Performance tab now displays the disk type (HDD vs. SSD) and shows the temperature of discrete graphics cards (GPUs).
Passwordless Sign-In: A new option allows you to require Windows Hello sign-in (Face, Fingerprint, or PIN) for Microsoft accounts on your device, effectively removing the need for traditional passwords.
Bluetooth Pairing via Notifications: Pairing supported Bluetooth devices is now done entirely through notifications, eliminating the need to open the Settings app manually.
