Released at the end of May, the latest Windows 10 version 2004 still isn't available for everyone or every device. Some devices from Microsoft's own Surface lineup were also waiting to receive the new version of the operating system. Nearly three months later, the Windows maker has now started to make the May 2020 Update available for some of these devices.

Windows 10 version 2004 is now available for several Surface devices, including Surface Laptop 2, Surface Laptop 3, Surface Pro X, and the Pro 5. Users haven't yet reported any bugs, which means the latest version may finally be ready for a broader rollout.
