the XML files unattend..xml OOBE.xml and ei.xml- Part 1

In this blog i am going to mention what are the different type of files that are available to us when we will have to take up an enterprise level deployment. So lets get started.


An EI.cfg is a prettu much a straight forward file. it is typically used in the scenario where you do not want that users will be prompted to select what version they want to install. A sample ET.cfg looks like this:

Edition specifies what edition you want to use, you must use get-wim info command againt the wim file and then carefully copy the value from there. In my case i wanted to use SERVERSTANDARD as my default SKU to get installed on the machine so i wil copy SERVERSTANDARD from it.

C:\Program Files (x86)\Windows Kits\8.1\Assessment and Deployment Kit\Deployment

The operation completed successfully.

Second in line is Channel, it can contain two values; OEM or volume based upon what version of OEM you have.

Third parameter is vl- it can contain two values, 0 or 1. If you are going to use volume licenses, you will use 1 else it will be 0.

So if i wanted to use the above wim file which will directly install Server standard edition, will be a volume license, my EI.cfg should be like this:




A very important note. If you are going to use unattend.xml; EI.cfg will be completely ignored.

Part 2 of this blog covers oobe.xml file.
