[xenadmin]

Hi! Love your work <3

Get-LatestOSBuild -OSName Server2025 -OSVersion 24H2

Doesn't show CU 08/2025 for Windows Server 2025.

Source: August 12, 2025—KB5063878: Update for Windows Server 2025 (OS Build 26100.4946)

Result: 26100.4652
Expected: 26100.4946

Can you have a look, please? Thank you!

Hi, Thank you. It will be because of changes to update naming "August 12, 2025—KB5063878: Update for Windows Server 2025 (OS Build 26100.4946)" I'll try to resolve as soon as possible with a new release.

Any progress on this? The same problem is true for September CU Windows Server 2025.

@xenadmin - please update and test v2509.1. Confirmation of issue resolved would be appreciated :)

Today we created new Citrix Master Images for Windows Server 2025 and this time the reporting worked as expected!

Thank you very much!
