Office 2003

Microsoft Office 2003 is a version of Microsoft Office, released on 19 August 2003.

New features
It included a refreshed UI, which changed its color in relation to the selected Windows XP visual style. However, this feature worked with the Luna theme only, because the Classic and custom themes caused the UI to be colored gray. OneNote and Infopath also debuted with this Office version. It is the last version of Office with the Office Assistant included. It needs to be activated manually, since it is disabled by default since Office XP.

Compatibility
This version of Office supports Windows 2000 Service Pack 3 to Windows 7 alongside their server counterparts, although it can unofficially run on Windows 8 and later.
