The software was originally written by Connectix, and was subsequently acquired by Microsoft. In July 2006 Microsoft released the Windows-hosted version as a free product. In August 2006 Microsoft announced the Macintosh-hosted version would not be ported to Intel-based Macintoshes, effectively discontinuing the product as PowerPC-based Macintoshes are no longer manufactured. Virtual PC emulates a standard PC and its associated hardware. Thus, it can be used to run nearly all operating systems available for the PC. However, issues can arise when trying to install uncommon operating systems that have not been specifically targeted in the development of Virtual PC.
