I downloaded the legitamate 30 day trial version from Microsoft's website about 3 months ago, and my trial has expired about 2 months ago. My trial came to an end on 7/22/2014, however, I am still able to use Microsoft Office at its fullest, but instead of showing "Document title.docx - Word" in the application name, it shows "Document title.docx - Word (Product Activation Failed)".
Question 1: Is it the actual full version of office? (by which I mean ALL the features are enabled)
Question 2: Is this legal?
Question 3: If both of the above are true, why does Microsoft allow this?
