If you're on Windows 7 and decide to install Office 2013 --- Don't do it --- for some [perhaps many] Windows 7 users its a SHOCK
If your on Windows 8 Office 2013 is perfect.
One of my clients just upgraded from Windows Vista to Windows 7 and at the same time upgraded his Office 2007 to Office 2010 and that went very smoothly --- then for some reason HE decided he wanted to go to Office 2013 and after the install a lot of stuff [far too many to mention] did not work the way he likes plus the LOOK of Office 2013 threw him completely off -- he is FURIOUS.--
