Improvements

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

• This update implements phase three of Distributed Component Object Model (DCOM) hardening. See KB5004442. After you install this update, you cannot turn off the changes using the registry key.

• This update addresses an issue that affects the registry size. It grows very large. This occurs because the registry entries are not removed when users sign out of an Azure Virtual Desktop (AVD) environment that uses FSlogix.

• This update affects the United Mexican States. This update supports the government’s daylight saving time change order for 2023.

• This update addresses an issue that might affect lsass.exe. It might stop responding when it sends a Lightweight Directory Access Protocol (LDAP) query to a domain controller that has a very large LDAP filter.

• This update addresses an issue that affects the Local Security Authority Subsystem Service (LSASS). LSASS might stop responding. This occurs after you run Sysprep on a domain-joined machine.

• This update addresses an issue that affects a computer account and Active Directory. When you reuse an existing computer account to join an Active Directory domain, joining fails. This occurs on devices that have installed Windows updates dated October 11, 2022 or later. The error message is, “Error 0xaac (2732): NERR_AccountReuseBlockedByPolicy: ‘An account with the same name exists in Active Directory. Re-using the account was blocked by security policy.’” For more information, see KB5020276.

• This update addresses an issue that affects the Routing and Remote Access Service (RRAS). RRAS cannot accept any new incoming virtual private network (VPN) connections.

• This update addresses an issue that affects Cluster Name Object of Failover Clustering on Azure virtual machines (VM). The issue stops you from repairing it.

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