Updates for Windows 10, version 2004 and Windows Server, version 2004
Windows 10 is a service, which means it gets better through periodic software updates.
The great news is you usually don’t have to do anything! If you have enabled automatic updates, new updates will automatically download and install whenever they’re available, so you don’t have to think about it.
On the left side of this page, you’ll find a list of all the updates released for this version of Windows. You can also find more information about releases and any known issues. Installing the most recent update ensures that you also get any previous updates you might have missed, including any important security fixes.
For more information about the update and how to get it, see:
Current status of Windows 10, version 2004 and Windows Server, version 2004
For the most up-to-date information about Known Issues for Windows and Windows Server, please go to the Windows release health dashboard.
Certain Japanese half-width Katakana and full-width Katakana characters that have a consonant mark aren’t interpreted as the same character. When you use the CompareStringEx() function with the NORM_IGNOREWIDTH flag to compare them, these characters are evaluated as different because of an issue in the sorting rule. This issue affects all the updates starting on June 9, 2020 for Windows 10, version 2004.
Important If you have not installed KB4586853or later on the computer, setting an invalid value in this registry might prevent the computer from starting up.
This workaround reverts the National Language Support (NLS) sorting rule to version 6.2, which is used in Windows 10, version 1909 and earlier. When sharing data between systems, consider applying the workaround consistently. If you use this workaround, conduct sufficient testing and evaluations to mitigate problems caused by different sorting rule versions on multiple systems.

IMPORTANT Starting in July 2020, all Windows Updates will disable the RemoteFX vGPU feature because of a security vulnerability. For more information about the vulnerability, seeCVE-2020-1036 and KB4570006. After you install this update, attempts to start virtual machines (VM) that have RemoteFX vGPU enabled will fail, and messages such as the following will appear:
If you re-enable RemoteFX vGPU, a message similar to the following will appear:
“The virtual machine cannot be started because all the RemoteFX-capable GPUs are disabled in Hyper-V Manager.”
“The virtual machine cannot be started because the server has insufficient GPU resources.”
"We no longer support the RemoteFX 3D video adapter. If you are still using this adapter, you may become vulnerable to security risk. Learn more (https://go.microsoft.com/fwlink/?linkid=2131976)”
