After spending quite a bit longer in the insider test rings, Windows 10 version 2004 has now been released.

  • Windows Hello is now supported as Fast Identity Online 2 (FIDO2) authenticator across all major browsers including Chrome and Firefox.
  • You can now enable passwordless sign-in for Microsoft accounts on your Windows 10 device by going to Settings > Accounts > Sign-in options, and selecting On under Make your device passwordless. Enabling passwordless sign in will switch all Microsoft accounts on your Windows 10 device to modern authentication with Windows Hello Face, Fingerprint, or PIN.
  • Windows Hello PIN sign-in support is added to Safe mode.
  • Windows Hello for Business now has Hybrid Azure Active Directory support and phone number sign-in (MSA). FIDO2 security key support is expanded to Azure Active Directory hybrid environments, enabling enterprises with hybrid environments to take advantage of passwordless authentication. For more information, see Expanding Azure Active Directory support for FIDO2 preview to hybrid environments.


Windows Defender has been revamped considerably to handle new classes of threats. Windows even now checks the UEFI which potentially could be a vector for malicious software. Memory is also checked to be sure applications are well behaved.


Hardware-accelerated GPU scheduling allows for improved gaming performance by giving your video card full control over managing video memory. The latency improvements inherent with this feature aren’t limited to DirectX either; they also work with Vulkan and OpenGL APIs.

If you’ve played an open-world game, you’ll know that cranking the level of detail can really impact performance as the CPU gets overwhelmed by issuing draw calls for each object in the environment. With Mesh Shading, the GPU intelligently controls level of detail selection and tessellation for objects, enabling rich, open worlds with hundreds of thousands of objects.


A change in the Reset Windows feature allows a user to download an updated windows installer instead of using whatever is present. The advantage is that the new image has all the update rollups included which saves time installing them. The idea is to leverage fast internet to allow users to refresh the whole operating system on demand.
