Improvements

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

• This update addresses an issue that stops hyperlinks from working in Microsoft Excel.

• 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 affects the Get-WinEvent cmdlet. It fails. The system throws InvalidOperationException.

• This update addresses an issue that affects Azure Active Directory (Azure AD). Using a provisioning package for bulk provisioning fails.

• 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 occurs when an access control policy denies you access to a resource. When you sign out, the system does not delete the POST Security Assertion Markup Language (SAML) Request cookie. This stops you from choosing other resources the next time you sign in.

• 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 Storage Replication setup. Setup might fail on machines that use non En-US locales.

• This update addresses an issue that affects cluster name object (CNO) repairs. This issue stops you from using Failover Clustering to repair a CNO on an Azure virtual machine (VM).

• This update addresses a known issue that affects guest virtual machines (VMs). If they run Windows Server 2022 on some versions of VMware ESXi, the OS might not start up. This issue only affects Windows Server 2022 VMs that have Secure Boot turned on. The affected versions of VMware ESXi are vSphere ESXi 7.0.x and below.

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