I installed windows 7 Ultimate with out a product key, I just never entered one when it asked me to input one and installation went fine! Do I need to purchase one and go back and enter it or can I run W7 fine with out it? Its been running fine for about 24 hours now.
Also I installed Microsoft Office and when I added the Excel Shortcut to the desktop the icon doesnt come up properly? It doesnt show the Excel Logo Icon, it has like a corrupt file icon. But when i double click it, it opens Excel without a problem?
It will nag you for a while and then if you dont put a valid key in - it will block many features from working.... so in summary... you need a key.
come back when you got a valid win7 install and we will see about the icons... seems a bit of a waste of time atm in view of your situation.
