Nickel

Nickel is the 22H1 development semester of Windows as a service that succeeds Cobalt (21H2) and will be followed by Copper (22H2) in the first half of 2022. Work on Nickel began in March 2021.

Early builds of Nickel still use the older Windows 10 branding and user interface as they predate the public unveil of Windows 11.
