MS25-OCT: Cumulative Update for Windows 11, version 25H2 - Windows 11 Version 25H2 - KB5066835 (x64)
I have a question regarding the implementation of the Fixlet for Windows 11 version 25H2.
Does the Fixlet for Windows 11 version 25H2 need to follow the same structure as version 24H2?
According to Microsoft’s website, the patch for 25H2 also uses the DISM command, just like the patch for 24H2.

Hi @taka, I’m currently working to address this issue. Thanks, Gus.
