Microsoft has just confirmed the system requirements for its upcoming Office 2010 suite.
The good news is that Office 2010 & Office 2007 system requirements are almost same except disk space requirement. In other words, if you are running Office 2007 on your PC, you needn’t worry about the Office 2010 system requirements.
According to Office 2010 Engineering blog, Office 2010 supports both 32-bit and 64-bit OS including Windows XP Service Pack 3 (SP3), Windows Vista Service Pack 1 (SP1) & above, Windows 7, Windows Server 2003, Windows Server 2008 and Windows Server 2008 R2.
