From the Microsoft post:
With organizations moving and adapting from remote to hybrid work scenarios, and essential workers continuing to support us all, it is more important than ever that we continue to provide you with the tools you need to remain protected and productive. In June, we announced Windows 10, version 20H2—and the availability of the first preview build in the Windows Insider Program. We then released a preview build to commercial customers in the Beta and Release Preview Channels for pre-release validation in August. We have continued to make improvements based on the feedback received through these programs and I am pleased to announce that we are beginning the availability of the October 2020 Update. Today’s post offers details on our measured and phased roll out approach, how you can get the update, and information to enable commercial organizations to begin targeted deployments.
Approach on update availability and rollout
In this work, learn and connect from home environment where people are relying on their PCs more than ever before, we are taking a measured seeker-based rollout approach to the October 2020 Update. We are throttling availability over the coming weeks to ensure a reliable download experience, so the update may not be offered to you right away. Additionally, some devices might have a compatibility issue for which a safeguard hold is in place, so we will not offer the update until we are confident that you will have a good update experience.
How to get the Windows 10 October 2020 Update
Beginning today, the October 2020 Update is available initially for users of select devices running Windows 10, version 1903 or later who are interested in experiencing the latest feature updates and are ready to install this release on their device. If you would like to install the new release, open your Windows Update settings (Settings > Update & Security > Windows Update) and select Check for updates. If the update appears, and you are running Windows 10, version 1903 or later, you can simply select Download and install to get started. Once the download is complete and the update is ready to install, we’ll notify you so that you can pick the right time to finish the installation and reboot your device, ensuring that the update does not disrupt your activities. People running the May 2020 Update will have a faster overall update experience because the update will install like a monthly update, just as it was for devices moving to Windows 10, version 1909 from version 1903.
As to what's in the October 2020 Update:
- Theme-aware tiles in Start – The redesigned Start menu has a more streamlined design that removes the solid color backplates behind the logos in the apps list, and applies a uniform, partially transparent background to the tiles. This design creates a beautiful stage for your icons, especially the Fluent Design icons for Office and Microsoft Edge, as well as the redesigned icons for built-in apps like Calculator, Mail, and Calendar.
- ALT+TAB between tabs in Microsoft Edge – We introduced ALT+TAB (task switcher) allowing you to toggle between open windows way back in Windows 2.0! In Windows 10, version 20H2, you can now use ALT+TAB to rotate between not only your open apps but also the tabs in Microsoft Edge. Now rotating through ALT+TAB will allow you to open Microsoft Edge in the specific tab you’re needing, not just the latest active tab. You can modify the ALT+TAB experience in Settings > System > Multitask.
- Improved notifications – Toast notifications now have the app’s logo in the top left corner of the notification, so you can immediately see where the notification is coming from. We’ve also turned off the Focus Assist notifications, which tells you when Focus Assist is enabled – whether via automatic rule or manually enabling it.
- Settings – We continue to improve the Settings page, adding more and more classic Control Panel capabilities. In addition to added settings, we also added a [COPY] button to Settings > System > About so you can easily copy that information and paste it into a help desk ticket. Watch for even more improvements to come!
- Tablet experience – Previously, when you detach a keyboard on a 2-in-1 device, a toast notification would appear asking if you wanted to switch into Tablet Mode. If you tapped Yes, you would switch into Tablet Mode. But selecting No would bring you the Windows desktop. In Windows 10, version 20H2, the default is changed: the toast notification no longer appears and you are instead brought into the new tablet experience. You can change this behavior in Settings > System > Tablet.
- Refresh rate of display – Change the refresh rate of your display, giving you a smoother motion. This change can be made at Settings > System > Display > Advanced display settings. Note that this may require supported hardware.
- Microsoft Edge (built on Chromium) – And of course, Windows 10, version 20H2 is the first version of Windows to come with Microsoft Edge browser built on the Chromium engine.
Good stuff. Update everything you have on the Desktop side and stay safe out there.
PS. The update isn't currently showing on my Surface devices, even under 'Optional updates'. So there's some blocking in place while Microsoft checks out various hardware under this build.
