Microsoft has released the next version of Windows 10, known as version 20H2 and featuring new changes and enhancements. Here's a convenient list detailing everything new in the update.

Just like the Windows 10 November 2019 Update, this upcoming release isn't a full feature update. That means when it's ready, the update will sit on top of the May 2020 Update instead, equating to a much smaller download and install period.

OS Details

  • Public name: Windows 10 October 2020 Update
  • Codename: N/A
  • Version: 20H2
  • Build: 19042
  • Released: October 2020

Version 20H2 changelog

  • Tabs in Microsoft Edge will now show up in the ALT+TAB interface.
  • Pinned websites will now show all open instances when hovering over its icon on the taskbar.
  • Notifications feature an updated layout with an X to dismiss notifications back into the Action Center.

Windows Settings

  • System > About now features copy buttons that will copy your system specifications to your clipboard.
  • There's a new Local Users and Groups modern device management (MDM) policy that allows an administrator to make granular changes to a local group on a managed device, on par with what has been available to devices managed with on-prem Group Policy (GP).

Miscellaneous changes

  • The new Microsoft Edge is now preinstalled.
  • The touch experience is more optimized when in desktop mode.
  • Focus Assist will no longer provide users with a summary of missed notifications when Focus Assist is turned off.

  • Improved support for non-ASCII file paths for Microsoft Defender Advanced Threat Protection (ATP) Auto Incident Response (IR).

Fixes

  • Fixed an issue that causes error messages to display in the English US (en-US) language instead of in the non-English language you selected. This occurs when you install a non-English language pack before installing the latest cumulative update.
  • Fixed the toast notification that appears at restart when you update from Windows 10, version 2004.
  • Fixed an issue that causes non-English strings to disappear, which might affect the text on the tiles of the Start menu.

  • Fxed an issue that might cause the Magnifier to stop working in Microsoft Excel in certain scenarios. As a result, Microsoft Excel might also stop working.
  • Fxed an issue that prevents you from installing some .msi apps. This occurs when a device is managed by a Group Policy that redirects the AppData folder to a network folder.

  • Fixed an issue that causes the Settings page to close unexpectedly, which prevents default applications from being set up properly.

  • Did you mean it's more optimised for touch when in TABLET mode?
  • No Desktop Mode. The bigger menus and right click menus etc.. will also appear when using Desktop Mode without a keyboard (e.g. 2-in-1 laptop with the keyboard behind the laptop).
  • I hope to get the second point of this exhausting list to be withdrawn.
  • Can be configured in settings/ multitasking
  • I am unable to remove them. These are two email accounts I used to have at my last job. I have no idea what to do. I've scoured the Internet. Thanks for your post though.
  • Can you make this wallpaper available for download?
  • The May 2020 update, was that the one I received in July? These things are confusing.
  • Visual features can be unlocked in 20H1 with .423 cumulative update. There's a registry hack that will enable the new start menu etc.
  • What is the hack? 🤔 Can you tell the process?
  • Here you go

  • Add this key to the registry (make a system backup first in case there are problems). Copy this in Notepad and save it as 20H2.reg (or anything as long as it's .reg) Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FeatureManagement\Overrides\0\2093230218]
    "EnabledState"=dword:00000002
