OFFICE 2010 SP1 - $OEM$, MSOCache and SIZE!

[hydroeon]

Greetings everyone

I'm currently in the process of creating an unattended Win7 image which includes Office 2010 SP1 which is installed in the OOBE section.

Basically I place the OFFICE 2010 SP1 folder in $OEM$ which gets copied over to the C driver and then I call the setup.bat inside that folder from the autounattend.xml.

Everything works well (apart from taking twice as long to install!! ).

However, the size of the installation grew by over 4GB!!! by simply adding office 2010 SP1. Obviously something is dodgy so here I am investigating

So far I've tracked the following:

1) Program Files folder weighing in at 884MB!! (go me I'm so clever )

2) MSOCache - 685MB

Now, I've got this feeling that for some reason the original $OEM$ folder files are also backup up somewhere which is about 1.1GB but I couldn't find anything on this.

I also don't understand where the other files are (over 1GB of them).

Oh and about that MSOCache - If I delete that nonsense, will it ask me for the CD if I try to install a built in Excel addon for example? (Assuming I've installed all features in the default installation)

I'm sensing that there are several GB which could be saved here

Hopefully somebody here can help
