Improvements

This non-security update includes quality improvements. When you install this KB:

  • This update addresses a known issue that affects the Local Security Authority Subsystem Service (LSASS). It might leak memory on domain controllers (DCs). This issue occurs after you install  KB5035857 (March 12, 2024). The leak occurs when on-premises and cloud-based Active Directory DCs process Kerberos authentication requests. This substantial leak might cause excessive memory usage. Because of this, LSASS might stop responding, and the DCs will restart when you do not expect it.

If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device.
