Addresses an issue that causes LSASS.exe to stop working because of a race condition that results in a double free error in Schannel.

This issue occurs after installing Windows updates from September 2020 and later.

You can now use fsutil to look for the $KERNEL.SMARTLOCKER.ORIGINCLAIM extended-attribute (EA) on a file. If this EA is present, then MI or ISG can run the file. You can use fsutil in conjunction with Enabling ISG and MI diagnostic events.

Adds a notification that tells you when your device is close to end of service (EOS). At EOS, your device will stop receiving important quality and security updates.

Addresses an issue with Administrative Template settings you configure using a Group Policy Object (GPO). When you change the value of the policy settings to NOT CONFIGURED, the system fails to remove the previous settings. This issue is most noticeable with roaming user profiles.

Addresses an issue that fails to show Extract all on the shortcut menu when you right-click an online-only ZIP file.

Updates the process for enrolling in online speech recognition. If you are already enrolled, you will see a message that asks you to review the new settings.

The new settings contain one button to turn on online speech recognition and another button that turns on the collection of your voice clips. If you turn on the collection of your voice clips, you can turn it off at any time using the same button in the new settings page.
