Remove any dependencies on this font type by selecting a supported font type. To display currently installed fonts, go to Settings > Personalization > Fonts. Application developers and content owners should test their apps and data files with the Adobe Type1 fonts removed. For more information, contact the application vendor or Adobe.
August 2024 DirectAccess DirectAccess is deprecated and will be removed in a future release of Windows. We recommend migrating from DirectAccess to Always On VPN. June 2024 NTLM All versions of NTLM, including LANMAN, NTLMv1, and NTLMv2, are no longer under active feature development and are deprecated. Use of NTLM will continue to work in the next release of Windows Server and the next annual release of Windows. Calls to NTLM should be replaced by calls to Negotiate, which tries to authenticate with Kerberos and only falls back to NTLM when necessary. For more information, see, Resources for deprecated features.[Update - November 2024]: NTLMv1 is removed starting in Windows 11, version 24H2 and Windows Server 2025.
June 2024 Driver Verifier GUI (verifiergui.exe) Driver Verifier GUI, verifiergui.exe, is deprecated and will be removed in a future version of Windows. You can use the Verifier Command Line (verifier.exe) instead of the Driver Verifier GUI. May 2024 NPLogonNotify and NPPasswordChangeNotify APIs Starting in Windows 11, version 24H2, the inclusion of password payload in MPR notifications is set todisabled by default through group policy in NPLogonNotify and NPPasswordChangeNotify APIs. The APIs may be removed in a future release. The primary reason for disabling this feature is to enhance security. When enabled, these APIs allow the caller to retrieve a user's password, presenting potential risks for password exposure and harvesting by malicious users. To include password payload in MPR notifications, set the EnableMPRNotifications policy to enabled. March 2024 TLS server authentication certificates using RSA keys with key lengths shorter than 2048 bits Support for certificates using RSA keys with key lengths shorter than 2048 bits is deprecated. Internet standards and regulatory bodies disallowed the use of 1024-bit keys in 2013, recommending specifically that RSA keys should have a key length of 2048 bits or longer. For more information, see Transitioning of Cryptographic Algorithms and Key Sizes - Discussion Paper (nist.gov). This deprecation focuses on ensuring that all RSA certificates used for TLS server authentication must have key lengths greater than or equal to 2048 bits to be considered valid by Windows.
TLS certificates issued by enterprise or test certification authorities (CA) aren't impacted with this change. However, we recommend that they be updated to RSA keys greater than or equal to 2048 bits as a security best practice. This change is necessary to preserve security of Windows customers using certificates for authentication and cryptographic purposes.

This change affects the following browsers: Application Guard Extension - Chrome and Application Guard Extension - Firefox. If you want to block unprotected browsers until you're ready to retire MDAG usage in your enterprise, we recommend using AppLocker policies or Microsoft Edge management service. For more information, see Microsoft Edge and Microsoft Defender Application Guard.

August 17, 2023 TLS 1.0 and 1.1 Over the past several years, internet standards and regulatory bodies have deprecated or disallowed TLS versions 1.0 and 1.1 due to various security issues. Starting in Windows 11 Insider Preview builds for September 2023 and continuing in future Windows OS releases, TLS 1.0 and 1.1 will be disabled by default. This change increases the security posture of Windows customers and encourages modern protocol adoption.

In a future release, any connection to a Wi-Fi network using these old ciphers will be disallowed. Wi-Fi routers should be updated to use AES ciphers, available with WPA2 or WPA3. 1903 Print 3D app 3D Builder is the recommended 3D printing app. To 3D print objects on new Windows devices, customers must first install 3D Builder from the Store. 1903 Companion device dynamic lock APIS The companion device framework (CDF) APIs enable wearables and other devices to unlock a PC. In Windows 10, version 1709, we introduced Dynamic Lock, including an inbox method using Bluetooth to detect whether a user is present and lock or unlock the PC. Because of this reason, and because non-Microsoft partners didn't adopt the CDF method, we're no longer developing CDF Dynamic Lock APIs. 1809 OneSync service The OneSync service synchronizes data for the Mail, Calendar, and People apps. We added a sync engine to the Outlook app that provides the same synchronization. 1809 Software Restriction Policies in Group Policy Instead of using the Software Restriction Policies through Group Policy, you can use AppLocker or Windows Defender Application Control to control which apps users can access and what code can run in the kernel. 1803 Offline symbol packages (Debug symbol MSIs) We're no longer making the symbol packages available as a downloadable MSI.

All other Sync your settings options continue to work provided your clients are running an up-to-date version of:wusa.exe /uninstall /kb:####### /quiet The wusa tool usage to quietly uninstall an update is deprecated. The uninstall command with /quiet switch fails with event ID 8 in the Setup event log. Uninstalling updates quietly could be a security risk because malicious software could quietly uninstall an update in the background without user intervention. 1507
