I really dislike Office 2013. Before with version 2007 and 2010 I could download and save all the trial versions. Then when I would reinstall Windows for a customer I could grab their software registry hive extract the office key, install the trial version I had which matched their key and reinstall office. The only trial for 2013 I've been able to locate is the Professional Plus 2013 32 / 64bit.
Most people have the Home and Student 2013
I'm also not a fan of of the new Office 2013 installer but that's a topic for another thread.
Is there a Home & Business / Home and Student 2013 and Trial version?
