Commercial platform Windows 11 N-2 and 5-year operating system supportability:
All newly introduced 2019 and later commercial platforms (Latitude, OptiPlex, and Dell Precision) will qualify and ship with the
most current factory installed Semi-Annual Channel Windows 11 version (N) and qualify (but not ship) the previous two versions
(N-1, N-2). The OptiPlex 5400 All-in-One will RTS with Windows 11 version v20H2 at time of launch, and this version will
determine the N-2 versions that are initially qualified for this platform.
For future versions of Windows 11, Dell continues to test the commercial platform with coming Windows 11 releases during
device production and for five years post-production, including both fall and spring releases from Microsoft.
For additional information about N-2 and 5-year Windows operating system supportability, see the Dell Windows as a Service
