Yes as above, easiest way is to use dism command to add all msu's found inside a specified folder. For example: dism /image:C:\Users\max\Desktop\win7lab\mount /Add-Package /PackagePath:"C:\Users\max\Desktop\win7lab\updates32" This single line adds every msu file found inside the updates32 folder to the mounted wim file automatically. I just download all the msu's and put them in the folder. Then after mounting my wim using dism, I run this command and watch it install them one after the other all automatically.
