- Task Manager CPU Reporting: There were ongoing issues with Task Manager incorrectly reporting CPU usage speed. Specifically, it would sometimes show architecture limitations rather than actual utilization speeds.

Key New Features in Windows 10 Insider Preview Build 19536
Despite being a "rebase" build (a foundational reset), Microsoft shipped several notable improvements. Here is the complete changelog for the Windows 10 Insider Preview Build 19536 20H2 full package.
4. Known Issues (from original release notes)
| Issue Area | Description |
|------------|-------------|
| Battery flyout | Battery icon tooltip incorrectly shows "X hours remaining" regardless of charge level. |
| Windows Security app | "Virus & threat protection" might show a blank screen or fail to load. |
| Game bar | Multiple audio device selections cause Game bar to misreport microphone status. |

2.1 Separation of Cortana and Search
The most prominent visual change in Build 19536 was the decoupling of Cortana and Search on the taskbar.
- Previous State: In previous versions (20H1 and earlier), the round Cortana button and the Search bar were often conflated or tightly integrated.
- New Behavior: In Build 19536, the Cortana button and the Search box are now two distinct entities. Clicking the Search box brings up the standard Windows Search interface, while clicking the Cortana button launches the digital assistant.
- Customization: Microsoft introduced separate context menus for each. Users can now hide the Cortana button or the Search box independently via the taskbar context menu. This change was a direct response to user feedback requesting a cleaner separation between local file searching and cloud-based assistant queries.

3.1 Display Enhancements

- Output:
- Previously: Fixed to desktop refresh rate.
- With Build 19536: Per-display refresh rate selection (e.g., 60 Hz for desktop, 144 Hz for games).
