Try using WSUS Offline Update
Checkmark the option that says you want to create a ISO image per selected product and language. Then simply click Start and it will download all the updates to the folder (make sure you remember where you downloaded the program, all files will be stored there, so you may want to move it to your desktop or something). Afterwards it will be in the iso folder.
Then on PC's you want to run it, just download virtual clonedrive
to mount the ISO and begin installing (if transferring over through USB, otherwise ignore this).
