Resolving Software Compatibility Issues
Whenever there is a new version of Windows launched, there are typically some issues that relate to ensuring backward compatibility. Most software is supported by the independent software vendor (ISV) for the specified lifespan of the software, which could also be aligned to one or more host operating system platforms. For example, Office 2003 was released by Microsoft in October 2003; it was compatible with Windows 2000 and supported on Windows XP and later. Mainstream support for Office 2003 ended on April 14, 2009, and extended support was terminated on April 8, 2014.
