As of my knowledge cutoff in September 2021, the Windows October 2020 update, also known as Windows 10 version 20H2, introduced several new features and improvements. Here are some notable features:

1. Start Menu Changes: The Start Menu received a visual refresh with a streamlined design and a more simplified look. The Live Tiles were also modified to have a uniform background color.
2. Alt+Tab Enhancements: The Alt+Tab task switcher was updated to include Microsoft Edge browser tabs alongside the traditional app switching. It allows you to quickly switch between open tabs in Microsoft Edge.
3. Improved Notification Experience: Notifications were enhanced to provide a more consistent and informative experience. App logos were added to notifications, and the Notification Center received a refined design.
4. System-wide Dark Mode: The October 2020 update extended the dark mode feature to more areas of the Windows interface, providing a consistent dark theme throughout the system.
5. Chromium-based Microsoft Edge: Windows 10 version 20H2 included the new Chromium-based version of the Microsoft Edge browser as the default browser, replacing the older EdgeHTML-based version.
6. Refresh Rate Selector: This update introduced a new option to select the desired display refresh rate from within the Windows settings. It allows users to choose a refresh rate that suits their display and hardware capabilities.
7. Improved Settings App: The Settings app received several enhancements, making it easier to navigate and access various system settings. Some settings were reorganized, and the search functionality was improved.
8. Enhanced Taskbar Previews: Taskbar previews were updated to display thumbnails of open windows when you hover over an app icon in the taskbar, providing a quick preview of the app’s content.

These are just a few notable features introduced in the Windows 10 October 2020 update. It’s worth noting that newer updates might have been released since then, so it’s always a good idea to check for the latest features and improvements provided by Microsoft.
