Microsoft Office 2013 is seriously ugly. There is way too much contrast in the UI design. It becomes difficult to look at after just a few minutes. Too much whiteness. There are options to change it to Grey and Dark grey but it really does very little to offset the harshness of the UI. Pretty much a fail.
Also Skydrive somehow enabled itself on my test computer. Here is how to remove it.
For 32-bit users – regsvr32 /u “%programfiles%\Microsoft Office\Office15\GROOVEEX.DLL”
For 64-bit users – regsvr32 /u “%programfiles(x86)%\Microsoft Office\Office15\GROOVEEX.DLL”
