February 14, 2023—KB5022838 (OS Build 14393.5717)

1/10/23 **REMINDER **On January 10, 2023, the public extension for servicing devices that have the Intel Atom Clover Trail processor ended. The January 10, 2023 security update was the last update for those devices. They will not receive monthly security and quality updates. Unfortunately, those devices do not meet the hardware requirements to upgrade to a newer version of Windows 10 or Windows 11. We recommend that you consider a new device that has Windows 11.

Highlights

Improvements

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

• This update addresses an issue that puts domain controllers (DC) in a restart loop. This occurs because the Local Security Authority Subsystem Service (LSASS) stops responding. The error is 0xc0000374. LSASS stops responding if you populate KrbTGT with the AltsecID on accounts that read-write and read-only DCs use.
• This update addresses an issue that affects AppV. It stops file names from having the correct letter case (uppercase or lowercase).
• This update addresses an issue that affects certain Internet of Things (IoT) devices. They lose audio.
• This update addresses an issue that affects searchindexer.exe. It randomly stops you from signing in or signing out. ​​​​​​​
  If you installed earlier updates, only the new updates contained in this package will be downloaded and installed on your device. For more information about security vulnerabilities, please refer to the new Security Update Guide website and the February 2023 Security Updates
