On July 12, 2006, Microsoft released Virtual PC 2004 SP1 for Windows free of charge, however 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 [[macOS|Mac OS X]] 10.2.8 or later for [[PowerPC]] and was a [[Proprietary software|proprietary]] [[commercial software]] product.<ref name="vpc-mac-main">{{cite web |title=Virtual PC 7 for Mac |url=https://www.microsoft.com/australia/office/mac/virtualpc7/default.aspx |url-status=dead |archive-url=https://web.archive.org/web/20100729173443/http://www.microsoft.com/australia/office/mac/virtualpc7/default.aspx |archive-date=July 29, 2010 |access-date=June 10, 2010 |work=Microsoft for Mac – Australian website |publisher=Microsoft corporation}}</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 [[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/ |archive-url=https://web.archive.org/web/20150920121236/http://www.zdnet.com/pictures/virtual-pc-2007-user-interface/ |url-status=dead |archive-date=September 20, 2015 |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> It initially did not support home editions of Windows as host OSes such as Windows XP Home Edition,<ref>{{Cite web |title=Microsoft Virtual PC 2007 on Windows XP Home Edition |url=https://www.labnol.org/software/tutorials/install-virtual-pc-2007-windows-xp-home/1539/ |access-date=2023-11-16 |website=Digital Inspiration}}</ref> Windows Vista Home Basic and Home Premium, however a hotfix for Virtual PC 2007 SP1 issued on February 20, 2009 (see below) rectified this. Windows XP Starter, [[Windows XP Media Center Edition]] and Windows Vista Starter is not supported on Virtual PC 2007, however the former and the latter are still supported as a guest OS. Support for Windows 2000 Professional as a host OS was dropped in Virtual PC 2007 and will not install at all on Windows 2000 hosts, however it is still supported as a guest OS.

"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>
