You can go and download the RC release for Windows Virtual PC and Windows XP mode now:

Some key changes in this release include:

  • Granular drive sharing

    In the settings on the virtual machine, you can select specific host computer drives to share with the virtual machine.

  • Manage USB devices with virtual applications

    While running virtual applications, you can manage USB devices by using the Virtual Applications icon on the task bar.

  • Windows XP Mode tutorial

    A Windows XP Mode RC tutorial, which introduces the product features, is displayed during Windows XP Mode Setup.

  • Jump list for virtual applications

    Right clicking on the virtual application icon for Windows XP Mode, on Windows 7 taskbar, displays a jump list that allows one to easily launch virtual applications from the taskbar.

  • Faster Windows XP Mode Setup

    Windows XP Mode Setup completes more quickly than in Windows XP Mode Beta.

  • Compact differencing disks

    You can compact the differencing disks to decrease the file size.

  • Ability to install Windows XP optional components

    Windows XP optional components can be installed in Windows XP Mode RC without prompting for Windows XP media.

  • Ability to choose a location to store virtual machine files for Window XP Mode RC

    When you are setting up Windows XP Mode RC, you can choose where to store all virtual machine files for Windows XP Mode RC. The default path is: %LOCALAPPDATA%\Microsoft\Windows Virtual PC\Virtual Machines\.

  • Option to turn off and discard changes when Undo disk is enabled for a virtual machine

    An additional option is available when you are turning off a virtual machine: Turn off and discard changes. This option will delete the current Undo disk, and turn off the virtual machine.

Please grab this release and let us know how it goes.

  • Any hope for computers with no VT extensions? As of now they won't even be able to upgrade to Windows 7 (because Virtual PC 2007 doesn't work on Windows 7, and the new Virtual PC requires VT extensions).

  • Hey,

    I've just installed Windows 7 (at last) and just tried the Virtual PC RC but to no avail. I just get the enable Virtualization in the Bios message appear. Initially my Dell Studio 16 (P8600) had Intel Virtualization disabled in the bios, but I still get this error message now it is enable.

    Could it be a chipset driver thing? Cause Im am currently running the default Windows ones as Dell has not released Windows 7 versions yet

  • How do I know which version of Virtual PC I have (beta or RC)? I downloaded mine just a week ago, on Jul. 30.

    Also, moving from beta to RC, is there any way to simply migrate the Virtual Windows XP applications previously installed?


  • There's any plans to make XP Mode works on a non VT machine?... because I have a computer with C2D T6600 processor and I cannot start this awesome Windows 7 Feature.

    Consider the trade off between speed and lack of this feature for users.

  • Look at what Microsoft has done by requiring hardware virtualization for XP Mode and Windows Virtual PC: The issue's not just that some random processors are missing it, but random BIOSes too are. The actual number of people who can try Windows VPC or XP Mode are very few as a result. I feel Microsoft should relax the requirement in a service pack or update till all of the mainstream computers ship with VT enabled at which point MS should switch to depend on hardware virtualization. None of the other VM vendors - VirtualBox, VMware and the upcoming announced Parallels solution require processor virtualization for XP mode-like seamless integration. I am sure Microsoft must be getting overwhelming number of demands to not require processor virtualization for such a critical component of the Windows 7 user experience.

  • Here is what I have found -

    1. upgraded notebook from W7 RC to RTM

    2. Uninstalled VPC 2007 SP1 to try Windows Virtual PC and XPMode

    3. Copied a VHD previously used on VPC 07 under W7 RC (always was fast) and created new VM on C:, running VHD on USB disk

    4. Installing new Integration features is a pain and it would be helpful if instructions said to uninstall VM Additions first

    5. I find it real slow, probably twice as slow as before on identical hardware & settings

    The VHD image is running W7 RC by the way

    I don't expect released software to run faster than RC versions which will be a shame if Windows Virtual PC just becomes the foundation for XPMode under W7 because most people historically have used VPC2007 for a lot more than just getting legacy apps from lazy software companies to work. i.e. Demo's, testing etc

  • When Integration Features are disabled resizing the VPC window works flawlessly. However, when Integration Features are enabled each time you resize the window the user gets logged off and then back on again (at least that what it looks like). Why is it so?

    At least it is better than in Windows Virtual PC Beta when you had to manually enter the password each time you resized the windows (if you didn't check the 'remember password' box).

    Why can't resizing be as smooth when integration features are on as it is when they are off?

  • Hi Ben,

    I'm having a few issues with Virtual PC RC running on Windows 7. I searcvhed around on MSDN/Technet for a Virtual PC forum but didn't find one hence posted here instead:

    I'd really really appreciate it if you or someone from your team could take a look. Basically my problem is that mouse clicks in the VM don't appear at the correct x,y place (hope that makes sense).

    Thanks in advance

  • Running this RC on Windows 7 Enterprise RTM, when I try to run a new VM I get an error, "Could not retrieve version of Integration Components." I've tried creating a VM using a fresh new VHD and an existing VHD from Virtual PC 2007 and it happens every time. Virtual PC simply won't run on Windows 7 RTM.

  • Found the issue. There is a group policy distributing settings for Remote Desktop Gateway out to all the clients. If that group policy is being distributed to your Windows 7 computer, you cannot run Windows Virtual PC. Here's where I got the clue:

    To temporarily solve this problem, go to HKLM\Software\Policies\Microsoft\Windows NT\Terminal Services and delete the two entries there relating to your organization's RD Gateway settings. Now you can at least get Windows Virtual PC RC to run until the next time your computer applies that policy.

    I classify this as a major bug. Hopefully before release someone will read this and it will get fixed.

  • Correction: The regedit entries to delete are not in HKLM, they're in HKCU: HKCU\Software\Policies\Microsoft\Windows NT\Terminal Services\ProxyName and HKCU\Software\Policies\Microsoft\Windows NT\Terminal Services\UseProxy

  • I have converted a plethora of Windows PC 2007 VMs to Windows Virtual PC (unload additions - double click the VMC - Install Integration Components) and on restart they find a few devices.   I have searched and searched and cannot find a simple list of emulated hardware.   It was in the Virtual PC 2007 help file but no similar entry comes in the WIndows Virtual PC help.

    What I can't believe that in 2009 the default audio device is still the Sound Blaster 16.   Surely the team could offer a choice.

  • I have installed 64 bit Windows 7 Ultimate RTM and 32 bit Virtual PC RC.  My PC is a Toshiba Core2 Duo 2.16GHz laptop with 4GB RAM. I am running 3 VMs on Internal Network as a W2K3 Domain Controller, Member Server and XP Host. The vhds were created in VPC 2007. I have not uninstalled Virtual Machine Additions or installed  Integration Components. The environment appears to be working correctly.

    My only query at this Right Alt - Delete key combination does not invoke login.

  • It's Ctrl-Alt-End now I believe. They did away with the previous "virtual display viewer" and now use Remote Desktop Connection instead, so we have all different ways of doing things. Another thing we lose is the ability to drag-and-drop files into the window which will be greatly missed. We also lost the status bar. Many great losses just to gain seamless windows. Personally I'm not convinced it's worth it.

  • It's painfully slow for me - compared to Virtual PC 2007. :(
