I am doing an upgrade for a customer from windows 8.1 to 8.1 enterprise,
according to Microsoft TMB, you can save settings, personal files, and applications doing the upgrade, see http://technet.microsoft.com/en-us/library/jj203353.aspx#EightOne
However, when I am trying to upgrade from 8.1 (same language, same architecture),
I only get two options:
1. Keep personal files.
Why is that? what am I doing wrong?
