'''Windows Virtual PC''' (successor to '''Microsoft Virtual PC 2007''', '''Microsoft Virtual PC 2004''', and '''[[Company:Connectix|Connectix]] Virtual PC''') is a [[Hardware virtualization|virtualization]] program for [[Software:Microsoft Windows|Microsoft Windows]]. In July 2006, Microsoft released the Windows version free of charge.<ref name="NEHUd">{{cite web | url = http://blogs.msdn.com/virtual_pc_guy/archive/2006/07/12/662535.aspx | title = Virtual PC is free! | date = July 12, 2006 | access-date = October 14, 2009 | archive-date = January 27, 2010 | archive-url = https://web.archive.org/web/20100127094258/http://blogs.msdn.com/virtual_pc_guy/archive/2006/07/12/662535.aspx | url-status = live }}</ref> In August 2006, Microsoft announced the Mac version would not be ported to Intel-based Macs, effectively discontinuing the product as PowerPC-based Macs would no longer be manufactured.

The newest release, Windows Virtual PC, does not run on versions of Windows earlier than [[Software:Windows 7|Windows 7]], and does not officially support MS-DOS or operating systems earlier than [[Software:Windows XP|Windows XP Professional SP3]] as guests.<ref name="wvpc-desc" /> The older versions, which support a wider range of host and guest operating systems, remain available. Windows Virtual PC is not supported on [[Software:Windows 8|Windows 8]] or [[Software:Windows 10|Windows 10]], and has been superseded by [[Software:Hyper-V|Hyper-V]].<ref name="s9aEA">{{cite web | title = Windows Virtual PC – FAQ | publisher = Microsoft.com | date = <!-- Undated. --> | url = http://www.microsoft.com/windows/virtual-pc/support/faq.aspx | access-date = July 10, 2009 | archive-date = March 16, 2013 | archive-url = https://web.archive.org/web/20130316070239/http://www.microsoft.com/windows/virtual-pc/support/faq.aspx | url-status = live }}</ref>

Virtual PC virtualizes a standard IBM PC compatible device and its associated hardware. Supported Windows operating systems can run inside Virtual PC. Other operating systems such as [[Software:Linux|Linux]] may run, but Microsoft does not provide support, or drivers (known as "Virtual Machine Additions") for these operating systems.<ref name="freecountry">{{cite web |first=Christopher |last=Heng |url=http://www.thefreecountry.com/emulators/pc.shtml |title=Free PC/Intel x86 Emulators and Virtual Machines |publisher=TheFreeCountry |work=thefreecountry.com |access-date=16 June 2013 |archive-date=January 5, 2013 |archive-url=https://archive.today/20130105022509/http://www.thefreecountry.com/emulators/pc.shtml |url-status=live }}</ref>

== History ==
Connectix Virtual PC, Microsoft Virtual PC 2004, Microsoft Virtual PC 2007, and Windows Virtual PC are successive versions of the same software. Windows Virtual PC only runs on Windows 7. The earlier Microsoft versions which run on older versions of Windows are still available and support operating systems older than Windows XP. Starting in Windows 8, Microsoft replaced Virtual PC with [[Software:Hyper-V|Hyper-V]].

[[File:Virtual PC 3 for Mac OS running Windows 95.png|thumb|Connectix Virtual PC version 3 in Mac OS 9, running a Brazilian Portuguese edition of Windows 95]]

Virtual PC was originally developed as a Macintosh application for System 7.5 and released by Connectix in June 1997.<ref name="Uq7GE">{{cite web|title=PC in a Mac|url=http://www.yale.edu/engineering/eng-info/msg00234.html|website=Yale Engineering Home newsgroup|publisher=[[Organization:Yale University|Yale University]]|access-date=21 March 2015|date=8 April 1997|quote=[...]Connectix Virtual PC is designed to run on Power PC systems running System 7.5 or later.

Connectix sold versions of Virtual PC bundled with a variety of guest operating systems, including Windows, OS/2, and [[Software:Red Hat Linux|Red Hat Linux]]. As virtualization's importance to enterprise users became clear, Microsoft took interest in the sector and acquired Virtual PC and [[Software:Microsoft Virtual Server|Virtual Server]] (unreleased at the time) from Connectix in February 2003.

Virtual PC 4 requires Mac OS 8.5 or later on a G3 or G4 processor, but running [[Software:Windows Me|Windows Me]], [[Software:Windows 2000|Windows 2000]] or Red Hat Linux requires Mac OS 9.0 or later. Virtual PC 4 was the first version with expandable drive images.

Virtual PC 5 requires Mac OS 9.1 or newer or [[Software:Mac OS X 10.1|Mac OS X 10.1]] or later.  For USB support, Mac OS X is recommended. To run Virtual PC 5 in Mac OS X, a 400&nbsp;MHz or faster processor is required.

Earlier versions of Virtual PC supported the following features: (now removed in Microsoft Virtual PC 2004, 2007, and Windows Virtual PC):
* Older versions of Virtual PC (v5.0 or earlier) may have the hard disk formatted after creating the [[VHD (file format)|Virtual Hard Disk]] file. Newer versions must partition and format the [[VHD (file format)|Virtual Hard Disk]] file manually.
* A ''Virtual Switch'' available in Virtual PC version 4.1 or earlier allows adding multiple network adapters.
* Older operating systems are supported with Virtual Machine additions.
* Older versions of Virtual PC for Macintosh can run on Mac OS 9.2.2 or earlier. Support of Apple [[Software:System 7|System 7]].5 are dropped in version 3.

Under agreement with Connectix, Innotek GmbH (makers of [[Software:VirtualBox|VirtualBox]], now part of [[Company:Oracle Corporation|Oracle]]) ported version 5.0 to run on an OS/2 host.<ref name="jG6CD">[https://web.archive.org/web/20060324234502/http://www.bityard.com/article.php?sid=100#Adds Innotek/Connectix Virtual PC]</ref> 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. A new version of the guest extensions was later included with Microsoft's Virtual PC 2004.

On July 12, 2006, Microsoft released Virtual PC 2004 SP1 for Windows free of charge, but the Mac version remained a paid software. The equivalent version for Mac, version 7, was the final version of Virtual PC for Mac. It ran on [[Software:MacOS|Mac OS X]] 10.2.8 or later for [[PowerPC]] and was a [[Proprietary software|proprietary]] [[Commercial software|commercial software]] product.<ref name="vpc-mac-main">{{cite web | url = https://www.microsoft.com/australia/office/mac/virtualpc7/default.aspx | title = Virtual PC 7 for Mac | work = Microsoft for Mac – Australian website | publisher = Microsoft corporation | access-date = June 10, 2010 | archive-date = July 29, 2010 | archive-url = https://web.archive.org/web/20100729173443/http://www.microsoft.com/australia/office/mac/virtualpc7/default.aspx | url-status = live }}</ref>

Virtual PC 2007 was released only for the Windows platform, with public [[Software release life cycle|beta]] testing beginning October 11, 2006, and production release on February 19, 2007. It added support for [[X86 virtualization|hardware virtualization]], "undo disks", transfer statistic monitor for disk and network, and viewing virtual machines on multiple monitors and support for Windows Vista as both host and guest. 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 [[Software:Remote Desktop Services|Remote Desktop Services]] from an Aero-enabled Windows Vista host, provided that the guest is running Windows Vista Business or a higher edition.<ref name="aero_savill" /><ref>{{cite web |last1=Conner |first1=Matt |title=Virtual PC 2007 User Interface |url=https://www.zdnet.com/pictures/virtual-pc-2007-user-interface/ |website=ZDNet |access-date=2 November 2021 |language=en-us |date=2007-03-06 |quote=Shows basic Input/Output activity through the network and storage interfaces.}}</ref><ref>{{cite web |title= Viewing online file analysis results for 'PXE_Diag.exe' |url=https://www.hybrid-analysis.com/sample/0294fa25155c8cfa4ff5fe9bd73b90a30f4f97dbe0e0cc0342ae3950af8fdba3/5d40771d0388388f827b23cb |website=www.hybrid-analysis.com |access-date=2 November 2021 |date=2019-07-30 |quote=IDE controller, Ethernet controller, Reads, Writes}}</ref>

"Undo disks" make it possible to revert virtual machines' state to an earlier point by storing changes into a separate <code>.vud</code> file since the last save to the main <code>.vhd</code> file, which can be used for [[Sandbox (computer security)|experimenting]]. The VHD file acts as a [[Snapshot (computer storage)|snapshot]]. The undo disk file (<code>.vud</code>) incrementally stores changes made by the virtual machine compared to the main Virtual hard disk drive (VHD) image, which can be applied or discarded by the user. If deactivated, changes are directly written to the VHD file.<ref>{{cite web |title=Microsoft Windows Virtual PC and Undo Disks |url=http://www.dabcc.com/microsoft-windows-virtual-pc-and-undo-disks/ |website=dabcc.com |archive-url=https://web.archive.org/web/20170804071608/http://www.dabcc.com/microsoft-windows-virtual-pc-and-undo-disks/ |archive-date=2017-08-04 |date=2009-08-19}}</ref>

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 [[Software:Windows Server 2008|Windows Server 2008]] Standard as a guest OS.<ref name="Ps7C3">{{cite web |last=Protalinski |first=Emil |url=https://arstechnica.com/journals/microsoft.ars/2008/05/15/microsoft-drops-some-details-on-upcoming-virtual-pc-2007-sp1 |title=Microsoft releases Virtual PC 2007 SP1 |work=[[Ars Technica]] |publisher=Condé Nast |date=15 May 2008 |access-date=16 June 2013 |archive-date=December 7, 2008 |archive-url=https://web.archive.org/web/20081207020639/http://arstechnica.com/journals/microsoft.ars/2008/05/15/microsoft-drops-some-details-on-upcoming-virtual-pc-2007-sp1 |url-status=live }}</ref><ref name="EuMcn">{{cite web | title = Virtual PC 2007 SP1 Release Notes | publisher = Microsoft | date = May 15, 2008 | url = https://www.microsoft.com/downloads/details.aspx?FamilyID=9f3d3eb5-5e03-4712-999c-e96f91bdf128&displaylang=en | access-date = June 28, 2009 | archive-date = June 27, 2009 | archive-url = https://web.archive.org/web/20090627181549/http://www.microsoft.com/downloads/details.aspx?FamilyID=9f3d3eb5-5e03-4712-999c-e96f91bdf128&displaylang=en | url-status = live }}</ref> A [[Hotfix|hotfix]] rollup for Virtual PC 2007 SP1, released February 20, 2009, solved networking issues and enhanced the maximum screen resolution to 2048×1920 (32-bit),<ref name="FjQoK">{{cite web |url=http://support.microsoft.com/kb/958162 |title=Description of the hotfix rollup package for Virtual PC 2007 Service Pack 1: February 20, 2009 (revision 2.0) |work=Support |publisher=[[Company:Microsoft|Microsoft]] |date=8 October 2011 |access-date=16 June 2013 |archive-date=March 3, 2015 |archive-url=https://web.archive.org/web/20150303211456/http://support.microsoft.com/kb/958162 |url-status=live }}</ref> enabling 16:9 resolutions such as 1920×1080.

Applications running in Windows XP Mode do not have compatibility issues, as they are actually running inside a Windows XP virtual machine and redirected using RDP to the Windows 7 host. Windows XP Mode may be used to run 16-bit applications; it includes NTVDM, although it might be impossible to run 16-bit applications that require hardware acceleration, as Windows Virtual PC does not have hardware acceleration.

Windows XP Mode is available free of charge to users of Windows 7 Professional, Enterprise, and Ultimate.<ref name="MS_XPM_brochure" /> Users of other editions of Windows 7 are not eligible to download and use it.<ref name="ms-vpc-faq" /><ref name="PM30q">{{cite web | url = http://www.microsoft.com/windows/virtual-pc/download.aspx | title = Download Windows XP Mode | work = Windows Virtual PC website | publisher = Microsoft Corporation | access-date = November 22, 2010 | archive-url = https://web.archive.org/web/20120628234800/http://www.microsoft.com/windows/virtual-pc/download.aspx | archive-date = June 28, 2012 | url-status = dead | quote = (After selecting an inappropriate edition of Windows 7) You are not eligible to download Windows XP Mode.

== Emulated environment ==
Virtual PC emulates the following environments:<ref name="NNtEa">{{cite web|work=Microsoft.com|title=Overview of the technical specifications of virtual machines in Virtual PC 2004|date=October 27, 2004|access-date=May 23, 2010|url=http://support.microsoft.com/kb/833144|archive-date=March 28, 2010|archive-url=https://web.archive.org/web/20100328153230/http://support.microsoft.com/kb/833144|url-status=live}}</ref>
* [[Company:Intel|Intel]] [[Engineering:Pentium II|Pentium II]] ([[32-bit|32-bit]]) processor (but virtualizes the host processor on Windows versions) with an Intel 440BX chipset.
* Standard [[Super video graphics array|SVGA]] [[Organization:Video Electronics Standards Association|VESA]] [[Engineering:Video card|graphics card]] ([[Engineering:S3 Trio|S3 Trio]] 32 [[Engineering:Peripheral Component Interconnect|PCI]] with 4 [[Megabyte|MB]] [[Video RAM (dual-ported DRAM)|video RAM]], adjustable in later versions up to 16&nbsp;MB by manually editing a virtual machine's settings file).
* System [[BIOS]] from [[Software:American Megatrends|American Megatrends]] (AMI).
* Creative Labs Sound Blaster 16 [[Engineering:Industry Standard Architecture|ISA]] [[Engineering:Plug and play|PnP]]. (When Windows Vista is installed as both the host (main) and guest (virtual) operating systems, settings are synchronized with the host and audio configuration is not required.)
* [[Company:Digital Equipment Corporation|DEC]] 21041 (DEC 21140 in newer versions) [[Ethernet]] [[Computer network|network]] card.
* Programs using undocumented features of hardware, exotic timings, or unsupported [[Opcode|opcode]]s may not work.

Implementation:
* The [[Software:Apple Macintosh|Macintosh]] version of Virtual PC uses [[Dynamic recompilation|dynamic recompilation]] to translate the [[X86|x86]] code used by PCs into equivalent [[PowerPC]] code for Macs.
* The Windows version of Virtual PC also uses dynamic recompilation, but only to translate x86 kernel mode and [[Real mode|real mode]] code into x86 user mode code; original user mode and [[Virtual 8086 mode|virtual 8086 mode]] code run natively.
* Guest call traps are used, especially for guest extensions, to accelerate emulation or offer additional features, such as integration with the host environment.
* Virtual PC and [[Software:Microsoft Virtual Server|Virtual Server]] encapsulate virtual hard disks in the [[VHD (file format)|Virtual Hard Disk]] (VHD) file format, for which Microsoft has made all documentation available under the [[Social:Microsoft Open Specification Promise|Open Specification Promise]].

Earlier versions of Virtual PC supported the following features: (now removed in Microsoft Virtual PC 2004, 2007, and Windows Virtual PC):
* Older versions of Virtual PC (v5.0 or earlier) may have the hard disk formatted after creating the [[VHD (file format)|Virtual Hard Disk]] file. Newer versions must partition and format the [[VHD (file format)|Virtual Hard Disk]] file manually.
* A ''Virtual Switch'' available in Virtual PC version 4.1 or earlier allows adding multiple network adapters.
* Older operating systems are supported with Virtual Machine additions.
* Older versions of Virtual PC for Macintosh can run on Mac OS 9.2.2 or earlier. Support of Apple [[Software:System 7#Version history|System 7.5]] was dropped in version 3.

== Virtual machine integration components ==
Windows Virtual PC may enable guest operating systems running inside virtual machines to interact with their host operating system beyond what is feasible between two physical computers, such as sharing physical hardware components or exchanging data. To do so however, ''integration components'' must be installed on the guest operating systems. When no integration component is installed, the only mean of communicating between two machines (either virtual or physical) is through a virtual network interface. Even the mouse cursor can only be controlled by one operating system (either real or virtual) at any given time. However, once the Integration Components are installed on the guest operating systems, the following features are automatically activated:<ref name="UMVS2">{{Cite book | last = Tulloch | first = Mitch | year = 2010 | title = Understanding Microsoft Virtualization Solutions, From the Desktop to the Datacenter | edition = 2nd | publisher = Microsoft Press | location = Redmond, WA | pages = 133–136 | url = http://download.microsoft.com/download/5/B/4/5B46A838-67BB-4F7C-92CB-EABCA285DFDD/693821ebook.pdf | access-date = November 27, 2010 | archive-date = November 6, 2010 | archive-url = https://web.archive.org/web/20101106000502/http://download.microsoft.com/DOWNLOAD/5/B/4/5B46A838-67BB-4F7C-92CB-EABCA285DFDD/693821EBOOK.PDF | url-status = live }}</ref>
* Mouse cursor sharing: Mouse cursor can be moved freely between the machines.
* Host-initiated shutdown: Virtual machine can be shut down, restarted or put into standby or hibernation via a set of [[Application programming interface|API]] functions.
* Time synchronization: The virtual machine's clock will be automatically synchronized with the host operating system's clock.
* Process responsiveness monitoring: Host operating system will be able to detect whether the software on the guest operating system is responsive or hung.
* Dynamic screen resolution: The screen resolution of the guest operating system can be changed by simply resizing the window in which it is running. However, the VM can be configured to allow only standard resolutions.

In addition to features described above, guest operating systems may also take advantage of the following integration features but only when the administrator activates them:<ref name="UMVS2" />
* Audio sharing: Audio played on the guest operating system may be brought to the host operating system and played on it.
* Clipboard sharing: Contents such as text, picture or everything that is cut or copied to [[Software:Clipboard (computing)#Microsoft Windows|Windows Clipboard]] maybe pasted in other machines.
* Printer sharing: Guest operating systems may print on the host operating system's printer. This feature should not be confused with File and Printer Sharing over an emulated network connection.
* Smart card sharing: [[Smart card]]s connected to host operating system may be accessed on guest operating systems.
* File sharing: Windows Virtual PC can also share [[Disk partitioning|disk partitions]] and [[Disk storage|disk drives]] of the host operating system with guest operating systems.<ref name="DnD-unsupported" /><ref name="Volume-sharing" /> This includes USB mass storage devices that are connected later.<ref name="8D8gU">{{cite web | url = http://blogs.technet.com/b/windows_vpc/archive/2009/12/14/usb-architecture-in-windows-virtual-pc.aspx | title = USB Architecture in Windows Virtual PC | work = Windows Virtual PC blog | publisher = Microsoft corporation | date = December 13, 2009 | access-date = August 20, 2010 | archive-date = June 17, 2011 | archive-url = https://web.archive.org/web/20110617110833/http://blogs.technet.com/b/windows_vpc/archive/2009/12/14/usb-architecture-in-windows-virtual-pc.aspx | url-status = live }}</ref>

== {{Anchor|Host operating systems}} {{Anchor|Guest operating systems}} Supported host and guest operating systems ==
Virtual PC allows multiple guest operating systems to run virtualized on a single physical host. Although a number of popular host and guest operating systems lack official Microsoft support, there are sometimes few, if any, technical obstacles impeding installation. Instead, a configuration may be unsupported due to Microsoft's own licensing restrictions,<ref name="bergstein" /><ref name="vista_eula_orig" /> or a decision to focus testing and support resources elsewhere, especially when production use of a legacy product fades.<ref name="vguy_win95" /><ref name="vguy_dosadd" />

A program manager on Microsoft's core virtualization team explains what official support entails:
{{blockquote|With each release of Virtual PC we spend a significant amount of time trying to decide which (guest) operating system should be officially supported.
