**Step-by-Step Process (using DISM)**



1. Extract the ISO: Extract the contents of your Windows ISO to a folder (e.g., C:\\ISO\_Files).
2. **Identify the Index**: Run the following command to find the index number for the specific edition you want to update (e.g., Windows Pro might be index 6):
   dism /Get-WimInfo /WimFile:E:\\Win11\_25H2\_English\_x64\\sources\\install.wim
   
3. **Mount the Image:** Create a mount folder (e.g., E:\\Mount) and mount the specific index (e.g., index 6):
   dism /Mount-Wim /WimFile:E:\\Win11\_25H2\_English\_x64\\sources\\install.wim /Index:6 /MountDir:E:\\Mount
   
4. **Integrate the MSU:** Add the .msu file to the mounted image:
   dism /Image:E:\\Mount /Add-Package /PackagePath:"E:\\windows11.0-kb5077181-x64.msu"
   
5. **Commit Changes and Unmount:** Save the changes and unmount the image:
   dism /Unmount-Wim /MountDir:E:\\Mount /Commit
   
6. Create New ISO: Use a tool like oscdimg (part of the Windows ADK) or AnyBurn to create a new, bootable ISO file from your modified folder.



**Discard Changes and Unmount:**

dism /Unmount-Image /MountDir:"E:\\Mount" /Discard

**List Mounted Images:**

dism /Get-MountedWimInfo
