• Starting with this release, we are displaying a dialog box to remind users about the End of Support (EOS) for Windows 8.1 in January 2023. If you click Remind me later , the dialog box will appear once every 35 days. If you clickRemind me after the end of support date , the dialog box will not appear again until after the EOS date. This reminder does not appear on the following:

  • Windows Embedded 8.1 Industry Enterprise and Windows Embedded 8.1 Industry Pro devices.
• When you use Encrypting File System (EFS) files over a remote Web Distributed Authoring and Versioning (WebDAV) protocol connection, the connection might be unsuccessful.
• NTLM authentication through an external trust is unsuccessful when serviced by a domain controller that has the January 11, 2022 or later Windows update installed. This issue occurs if the DC is in a non-root domain and does not hold the global catalog (GC) role. Impacted operations may log the following errors:
  • The security database has not been started.
  • The domain was in the wrong state to perform the security operation.
  • 0xc00000dd (STATUS_INVALID_DOMAIN_STATE)

• Addresses a known issue in which Windows Servers that use the Routing and Remote Access Service (RRAS) might be unable to correctly direct Internet traffic. Devices which connect to the server might not connect to the Internet, and servers can lose connection to the Internet after a client device connects.
