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 the 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 and you will be able to upgrade to Office 2010 without making any changes to your PC’s hardware.
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. Although it officially doesn’t support XP SP1 or SP2, there is a workaround out there to install Office 2010 on Windows XP SP2.
In short, it supports all recent versions of the Windows operating system. If you are installing Office 2010, we encourage you to install the 64-bit version, especially if you are running 64-bit Windows OS.
