Missing Windows Server 2025 specific entry

Missing information

Description

Can you please clarify which update is related to Windows Server 2025? There are clear entries for 2022, 2019, and 2016, but not for the 2025. The information becomes a bit confusing when cross referencing with Microsoft Feed [1].

Example, the KB5100998 (July) applies to Microsoft server operating system, version 24H2. I assume this is the Windows Server 2025, right? However, the feed [1] says something else, that KB applies to Windows 11 Version 25H2 only:

<vuln:Remediation Type="Vendor Fix">
<vuln:Description>5100998</vuln:Description>
<vuln:URL>
https://catalog.update.microsoft.com/v7/site/Search.aspx?q=KB5100998
</vuln:URL>
<vuln:ProductID>12079-20438</vuln:ProductID>
<vuln:ProductID>12079-20437</vuln:ProductID>
<vuln:AffectedFiles/>
<vuln:RestartRequired>Maybe</vuln:RestartRequired>
<vuln:SubType>Security Update</vuln:SubType>
<vuln:FixedBuild>2.0.50727.9182 & 3.0.30729.9168 & 4.8.9340.0</vuln:FixedBuild>
</vuln:Remediation>

Both ProductID 20438 and 20437 shows Windows 11 Version 25H2:

{
      "ProductID": "20437",
      "Value": "Windows 11 Version 25H2 for ARM64-based Systems"
  },
  {
      "ProductID": "20438",
      "Value": "Windows 11 Version 25H2 for x64-based Systems"
  },

The problem is that there no entry for "Server and 24H2" on that feed. The only entry that explicit state Windows Server uses a different ProductID.

  {
      "ProductID": "12079-12437",
      "Value": "Microsoft .NET Framework 3.5 AND 4.8.1 on Windows Server 2025 (Server Core installation)"
  },
  {
      "ProductID": "12079-12436",
      "Value": "Microsoft .NET Framework 3.5 AND 4.8.1 on Windows Server 2025"
  },

by checking the above ProductID, they are affected by a different KB (KB5101003) that is not listed in [2] nor in Catalog page as well [3].

<vuln:ProductID>12079-12436</vuln:ProductID>

</vuln:Remediation>

Asks:

1. Can you please confirm KB5100998 applies for Windows Server 2025?
2. Can you add a explicit entry to include Windows Server 2025?
3. Why there is a discrepancy between KB5100998 vs KB5101003 when both seem to be related to same OS ?
