After installing the April 2024 security update (KB5036960) on domain controllers (DCs), you might notice a significant increase in NTLM authentication traffic. This issue is more likely to affect Active Directory (AD) deployments already servicing a large number of NTLM authentication requests where a small number of Primary Domain Controllers (PDCs) are supporting a large number of read-write Backup Domain Controllers (DCs) and Read Only Domain Controllers (RODCs).
Note: In rare instances, Windows Servers running the Domain Controller (DC) role might experience Local Security Authority Subsystem Service (LSASS) crashes resulting in a reboot.
Resolution: This issue was resolved by Windows updates released May 14, 2024 (KB5037823), and later. We recommend you install the latest security update for your device. It contains important improvements and issue resolutions, including this one.
Affected platforms:
Client: none

Issue with Kerberos requests on domain controllers may cause LSASS memory leaks
| Status | Originating update | History |
|---|---|---|
| Resolved KB5037426 | KB5035885 2024-03-12 | Resolved: 2024-03-22, 14:30 PT Opened: 2024-03-20, 18:39 PT |
Following installation of the March 2024 security update, released March 12, 2024 (KB5035885), Local Security Authority Subsystem Service (LSASS) may experience a memory leak on domain controllers (DCs). This is observed when on-premises and cloud-based Active Directory Domain Controllers service Kerberos authentication requests.
Extreme memory leaks may cause LSASS to crash, which triggers an unscheduled reboot of underlying domain controllers (DCs).
Note: This issue does not occur on Home devices. It affects only environments in organizations using some Windows Server platforms.
Resolution: This issue was resolved in the out-of-band (OOB) update KB5037426, which is only available via the Microsoft Update Catalog. We strongly recommend you do not apply the March 2024 security update on DCs and install KB5037426 instead. As this is a cumulative update, you do not need to apply any previous update before installing KB5037426. To install this update, search for KB5037426 in the Microsoft Update Catalog. The OOB update can then be manually imported to Windows Server Update Services (WSUS) and Configuration Manager. For guidance, see WSUS and the Microsoft Update Catalog.
If you manage update catalogs in Configuration Manager, please check the section Import updates. If you with you work with software update synchronization in Configuration Manager, review the steps on Import updates from the Microsoft Update Catalog. For more information about the Microsoft Update Catalog, visit Microsoft Update Catalog - FAQs.
Important: This update (KB5037426) is not available from Windows Update and will not install automatically.
Affected platforms:
- Client: None
- Server: Windows Server 2022; Windows Server 2019; Windows Server 2016; Windows Server 2012 R2

Some issues related to printer configurations are being observed on Windows devices. Microsoft is investigating this issue and coordinating with partners on a solution.
Symptoms can include the following:
- Some Windows devices are installing the HP Smart app.
- Printers may show LaserJet M101-M106 model information regardless of their manufacturer. Printer icons might also be changed.
- Double clicking on a printer displays the on-screen error "No tasks are available for this page".
Note: Our investigations indicate that this issue is not caused by an HP update. In most cases, it should be possible to use the printer as expected, including queueing printing jobs, as well as other features such as copy, scan, or fax. Printers on the device will continue to use the expected drivers for printer operations. However, this issue might affect associations with other manufacturer-supplied printer apps used to extend basic printer capabilities. If this is the case, some or all of those extended functions might not work.
Resolution: You can resolve this issue by downloading and executing one of the files listed in the article KB5034510 Printer Metadata Remediation Tool – December 2023. In addition to this tool, a critical troubleshooter is being gradually rolled out to all affected Home and non-managed business devices. Critical troubleshooting happens automatically in the background and won’t get in the way of using your device. To learn more about critical and recommended troubleshooters, see Keep your device running smoothly with recommended troubleshooting.

The correct default currency might not display or be used in Windows devices which have locale set to Croatia. This can affect applications which retrieve the device's currency for purchases or other transactions.
Earlier this year, Croatia joined the Eurozone, changing its currency from the Kuna to Euro. Windows Locale data for Croatia will be updated for this change in the short term.
Workaround: Changing the currency in Windows can help. This can be accomplished via the Windows Control Panel.
- Open the "Windows Region" settings. This can be done in one of the following ways:
- Open "Control Panel" from the start menu and select "Change date, time, or number formats" under "Clock and Region"
- On your keyboard, press and hold the Windows key, then press the letter R. This will open the "Run" window. Type INTL.CPL into the Open field,
- In the Region settings, choose one of the 2 locales for Croatia:
- Croatian (Bosnia & Herzegovina)
- Croatian (Croatia)
- In this same window, click the "Additional settings" button. Once there, click the "Currency" tab.
- Change the currency symbol from "KN" to Euro, "€"
Additional information can be seen here: Currency formatting - Globalization | Microsoft Learn.
Manually changing currency might also be an option in some applications. Although this won't change the device’s default currency, this could allow usage of the application with the desired currency preference. Some applications might not allow this manual change. Please view the settings and documentation for your applications.
