Windows 11 22H2 codename Nickel or Sun Valley 2 may be signed-off as early as February 4, according to code from a script in an internal Insider build. Further, 22H2 will be designated "config complete" on March 4 after which current Dev channel Insiders will begin the transition to Windows 11 22H3 codename Copper. The 22H2 build will then be tested in the Beta and Release Preview channels before going public later this year.
