New features and changes[edit | edit source]

APIs[edit | edit source]

  • Power Grid Forecast API has been implemented. It is designed to minimize environmental impact by shifting background tasks to times when more renewable energy is available in the local electrical grid.
  • Support of key protection with virtualization-based security (VBS) has been implemented into Cryptography API: Next Generation (CNG) framework.[1]
  • A new EFFECTIVE_POWER_MODE enumeration has been implemented into Effective Power Mode API for indicating the effective power mode the system is running.

Miscellaneous[edit | edit source]

  • The reported version string has been changed from "23H2" to "24H2".
  • A new power setting GUID GUID_ENERGY_SAVER_STATUS (550E8400-E29B-41D4-A716-446655440000) has been implemented to represent energy saver status notification. Applications that register for this notification can save varying degrees of power depending on what energy saver mode is in effect.
  • Microsoft Defender Application Guard (MDAG) for Office and Edge is deprecated, and is no longer available as a feature on demand starting from this build.

Bugs and quirks[edit | edit source]

  • Applying the WinPE-Powershell optional component may not properly install Powershell in WinPE.
  • The Feedback Hub app may not work properly due to known issues.
  • Archiving eventlogs with wevtutil al command may cause the Windows Event Log service to crash, and the archive operation to fail.
