I recently bought an Inspiron 15" 3521 and it came with a free Microsoft Office trial pack for a year.
But the laptop didn't come with any activation codes, and I was wondering if I needed to request them from Dell?
How do I activate the trial pack?
The trial version is good for 60 days - not a year. You can get a key for it from Microsoft
Note that office 2013 is licensed two ways - by purchase (permanent) or by yearly subscription (called Office 365).
