Office 2003

Microsoft Office 2003 is a version of Microsoft Office, which was released to manufacturing on 19 August 2003 and then to consumers two months later on 21 October.

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
System requirements were raised to Windows 2000 SP3 and Windows XP SP1. 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.
