• This update addresses an issue that affects UI Automation and caching mode.

• This update affects Windows Autopilot profiles. The process to download the Windows Autopilot policy is more resilient. This helps when a network connection might not be fully initialized. This update increases the retry attempts when you try to download the Windows Autopilot profile.  

• This update addresses an issue that causes your device to restart when you do not expect it. This occurs after you restore a system.

• This update affects user mode printer drivers. They unload unexpectedly. This occurs when you print from multiple print queues to the same printer driver.

• This update addresses an issue that affects Xenon or Argon containers. They do not start.

• This update affects Windows Server: Azure Edition. It is easier to view attestation failure notifications.

• This update addresses an issue that affects an Application Virtualization (App-V) environment. Copy operations within it stop working. This occurs after you install the April 2023 update.

• This update addresses an issue that blocks external connections. This occurs when you set up a Kubernetes load balanced service and turn on session affinity.

• This update addresses an issue that affects NCryptGetProperty(). Calling it with NCRYPT_KEY_TYPE_PROPERTY returns 0x1 instead of 0x20. This occurs when the key is a machine key.

• This update includes quarterly changes to the Windows Kernel Vulnerable Driver Blocklist file, DriverSiPolicy.p7b. It adds to the list of drivers that are at risk for Bring Your Own Vulnerable Driver (BYOVD) attacks.

• This update addresses an issue that affects Windows LAPS. Its PasswordExpirationProtectionEnabled policy fails to turn on the setting.

• This update addresses an issue that affects the refsutil.exe inbox utility. Options, like salvage and leak, do not work well on Resilient File System (ReFS) volumes.

• This update addresses an issue that might affect a large reparse point. You might get a stop error when you use NTFS to access it. This issue occurs after a canceled FSCTL Set operation changes the reparse tag.

• This update addresses an issue that affects a machine that is used as a remote desktop session (RDS) host. An RDR_FILE_SYSTEM (0x27) stop error occurs. Because of this, everyone that uses RDS starts up from this machine.

• This update addresses a known issue that affects virtual machines (VMs) that run on VMware ESXi hosts. Windows Server 2022 might fail to start up. The affected VMs will receive an error with a blue screen and a stop code: PNP DETECTED FATAL ERROR.

• This update addresses an issue that affects a COM+ component. It might stop responding. This occurs because of a deadlock during COM+ Just-in-Time (JIT) activation. However, this part of this update is off by default for this version of Windows. If you have this issue, you must contact Microsoft support to turn it on.
