While this report is labeled for "20H2," it is important to note that features in this specific build were often considered experimental groundwork that would eventually ship in 20H2 (and later 21H1).
- 20H2 Strategy: The actual commercial release of 20H2 would eventually become a "scoped" update, delivered as an enablement package on top of 20H1. The experimental features seen in 19536 (like the Start Menu theme improvements) were refined over the subsequent months before being finalized for the 20H2 release.
