MDT/SCCM 2010/2012 - Adding Optional Language Packs for Windows 7 to appear Optional in the Language Pack Window

There was little documentation on how to get a language pack to appear as an optional installation in the MDT 2010 process. You might first think to install it as an update as I did, but this is wrong unless you want it defined as a mandatory installation in the customsettings.ini file. So here is how to make the language pack window appear with all of the language packs you installed:

1. In the customsettings.ini file, add the line SkipPackageDisplay=NO
2. Create a folder under Applications names Language Packs
3. Create a new application that installs the lp.cab file
1. Quiet Install Command: pkgmgr.exe /ip /m:<Path to cab file>\lp.cab

You will need to create a separate application for each language pack that you want to make optional. That is all that's to it!
