On May 15, 2008, Microsoft released Virtual PC 2007 Service Pack 1, which added support for both Windows XP SP3 and Windows Vista SP1 as guest and host OSes, as well as Windows Server 2008 Standard as a guest OS. (The Windows Aero interface is disabled on Windows Vista guests due to limitations of the emulated video hardware however, Aero effects can be rendered by connecting to the guest via Remote Desktop Services from an Aero-enabled Windows Vista host, provided that the guest is running Windows Vista Business or a higher edition.) It added support for hardware virtualization, viewing virtual machines on multiple monitors and support for Windows Vista as both host and guest. Virtual PC 2007 was released only for the Windows platform, with public beta testing beginning October 11, 2006, and production release on February 19, 2007. It ran on Mac OS X 10.2.8 or later for PowerPC and was a proprietary commercial software product. The equivalent version for Mac, version 7, was the final version of Virtual PC for Mac. On July 12, 2006, Microsoft released Virtual PC 2004 SP1 for Windows free of charge, but the Mac version was not made free. Virtual PC 2007 running the Live CD OS Knoppix A new version of the guest extensions was later included with Microsoft's Virtual PC 2004. This version also included guest extensions (VM additions) for OS/2 guests, which could run on Windows, OS/2 or Mac OS X hosts using Virtual PC versions 5, 6 or 7. Under agreement with Connectix, Innotek GmbH (makers of VirtualBox, now part of Oracle) ported version 5.0 to run on an OS/2 host. Support of Apple System 7.5 are dropped in version 3. Older versions of Virtual PC for Macintosh can run on Mac OS 9.2.2 or earlier.Older operating systems are supported with Virtual Machine additions.A Virtual Switch available in Virtual PC version 4.1 or earlier allows adding multiple network adapters.Newer versions must partition and format the Virtual Hard Disk file manually.

Virtual PC 5 requires Mac OS 9.1 or newer or Mac OS X 10.1 or later. Virtual PC 4 was the first version with expandable drive images. Virtual PC 4 requires Mac OS 8.5 or later on a G3 or G4 processor, but running Windows ME, Windows 2000 or Red Hat Linux requires Mac OS 9.0 or later. As virtualization's importance to enterprise users became clear, Microsoft took interest in the sector and acquired Virtual PC and Virtual Server (unreleased at the time) from Connectix in February 2003. Connectix sold versions of Virtual PC bundled with a variety of guest operating systems, including Windows, OS/2, and Red Hat Linux. The first version of Virtual PC designed for Windows-based systems, version 4.0, was released in June 2001. Virtual PC was originally developed as a Macintosh application for System 7.5 and released by Connectix in June 1997. Virtual PC by ConnectixĬonnectix Virtual PC version 3 in Mac OS 9, running a Brazilian Portuguese edition of Windows 95 Microsoft then replaced this with Hyper-V. The earlier Microsoft versions which run on older versions of Windows are still available and support operating systems older than Windows XP. Windows Virtual PC runs only on Windows 7 and only supports running Windows XP Professional and later. HistoryĬonnectix Virtual PC, Microsoft Virtual PC 2004, Microsoft Virtual PC 2007, and Windows Virtual PC are successive versions of the same software. Other operating systems such as Linux may run, but are not officially supported, and Microsoft does not provide the necessary "Virtual Machine Additions" (which include essential drivers) for Linux. Supported Windows operating systems can run inside Virtual PC. Virtual PC virtualizes a standard IBM PC compatible device and its associated hardware. Starting with Windows 8, Hyper-V supersedes Windows Virtual PC. The older versions, which support a wider range of host and guest operating systems, remain available. The newest release, Windows Virtual PC, does not run on versions of Windows earlier than Windows 7, and does not officially support MS-DOS or operating systems earlier than Windows XP Professional SP3 as guests. In August 2006, Microsoft announced the Macintosh version would not be ported to Intel-based Macintosh computers, effectively discontinuing the product as PowerPC-based Macintosh computers are no longer manufactured. In July 2006 Microsoft released the Windows version as a free product. Windows Virtual PC (successor to Microsoft Virtual PC 2007, Microsoft Virtual PC 2004, and Connectix Virtual PC) is a virtualization program for Microsoft Windows.
