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.

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)](https://csrc.nist.gov/CSRC/media/Projects/Key-Management/documents/transitions/Transitioning_CryptoAlgos_070209.pdf). 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.| March 2024| | Test Base | [Test Base for Microsoft 365](/microsoft-365/test-base/overview), an Azure cloud service for application testing, is deprecated.

To learn more about Edge for Business security capabilities, see [Microsoft Edge security for your business](/deployedge/ms-edge-security-for-business).

**[Update - October 2024]**: Starting with Windows 11, version 24H2, Microsoft Defender Application Guard, including the [Windows Isolated App Launcher APIs](/windows/win32/api/isolatedapplauncher/), is no longer available.

**[Update - April 2024]**: Because Application Guard is deprecated there will not be a migration to Edge Manifest V3. The corresponding extensions and associated Windows Store app will not be available after May 2024. This affects the following browsers: *Application Guard Extension - Chrome* and *Application Guard Extension - Firefox*. If you want to block unprotected browsers until you are ready to retire MDAG usage in your enterprise, we recommend using AppLocker policies or [Microsoft Edge management service](/deployedge/microsoft-edge-management-service).
