Hi Boopathi S,
You actually do not need to extract the .msu file to install Windows 11 updates. DISM natively supports installing the .msu package directly.
To install it quickly and effectively, simply leave the downloaded update as an .msu file, open an elevated Command Prompt, and run the following command:
DISM /Online /Add-Package /PackagePath:"C:\Path\To\Update.msu"
(Note: If you have multiple updates to install, you can put all the .msu files into a single folder and point the PackagePath directly to that folder (e.g., C:\Packages) to let DISM discover and install them all at once).
I hope this makes your deployment process easier. If this answers your question, please consider marking it as Accept Answer.
