NTLM and PowerShell security measures strengthened

Security adjustments were made to the NTLM authentication protocol. The update configures clients to offer NTLM message signing by default on non-anonymous connections. This change protects against NTLM relay attacks and provides an auditing mechanism to identify connections that do not use signing.

On the Windows PowerShell side, stricter encoding validation standards were introduced for script signing and signature verification processes. Scripts containing invalid UTF-8 encoding may now fail validation, even if they were previously accepted. Microsoft stated that affected scripts must be saved in UTF-8 BOM (Byte Order Mark) format and re-signed.

Other system fixes and download options

Other technical details included in the package are listed below:

• Secure Boot: The coverage of devices eligible to automatically receive new Secure Boot certificates was expanded. Certificate deployment will continue over the coming months on supported PCs and unmanaged enterprise devices.
• Remote Desktop (RDP): An RDP connection issue that failed on the client side due to a certificate mismatch following the October 2026 non-security preview update was resolved.
• Date and Time Adjustment: Daylight Saving Time (DST) rules for Cuba for 2026-2027 were updated. Cuba will remain in the UTC-04:00 time zone, skipping the November 2026 and March 2027 transitions. The country will return to UTC-05:00 in November 2027 and resume its standard schedule in 2028.

Microsoft reported that there are no known issues or bugs associated with these update packages. The patches can be installed automatically via Windows Update. Users wishing to install the update offline can download the KB5132061 and KB5131087 packages directly from the Microsoft Update Catalog website.
