The Virtual PC team is thrilled to announce the availability of KB977206 which allows our customers to use Windows Virtual PC and Windows XP Mode on non-HAV (Hardware-Assisted Virtualization) machines. Windows XP Mode continues to use hardware virtualization such as Intel Virtualization Technology (Intel® VT) or the AMD-V™ chipset when available but it no longer requires them. A number of our customers and partners have been asking us to support a wider range of PC’s including those without HAV capability and we have delivered this software patch to address their needs. We believe that this change simplifies the customer experience and makes this benefit accessible to many more PCs.
Download the software update for 32-bit host operating systems from here and for 64-bit host operating systems from here.
The KB article describes the various scenarios under which the software update must be installed. Ensure that Windows Virtual PC is installed before applying this fix.
Some FAQ’s around this update:
Q: How do I check the HAV capability of my machine?
A: Download and run the Microsoft Hardware-Assisted Virtualization Detection Tool. Go through the user guide for detailed description of the result.
Q: I have a machine with a HAV enabled processor, which has Windows Virtual PC and Windows XP Mode running. Do I need to apply this fix?
A: Short Answer – No
Long Answer – The fix is primarily targeted for non-HAV machines. If you have a functioning setup, then you can opt to not apply this fix. However please note that this update contains the fix for the power state issue seen (with Windows Virtual PC installed) on Intel® Clarkdale/Arrandale processor (http://support.microsoft.com/kb/977632) and it is recommended that you apply this update on that specific hardware. If you are an IT Administrator with a heterogeneous mixture of machines (HAV plus non-HAV machines), you can deploy this fix on all the machines. The user experience and performance on a HAV enabled machine before and after applying this fix will continue to be the same.
Q: I have a machine with a HAV capable processor (i.e the HAV setting is not enabled in the BIOS yet). Do I need to apply this fix?
A: For Windows XP Mode (or any Windows XP SP3 guest OS) users, we expect the performance to be comparable on HAV and non-HAV processors, however if you are planning to use any other guest OS we recommend that you enable the HAV setting in the BIOS rather than applying the patch.
Q: I have a non-HAV box and I wish to use a Windows Vista/Windows 7 VM using Windows Virtual PC. Is it possible?
A: This fix is primarily targeted towards users who need to run their productivity applications in Windows XP Mode (or any Windows XP SP3 virtual machine) on non-HAV machines. Hence you would need a HAV capable processor if you need to run a Windows Vista or Windows 7 virtual machine on Windows Virtual PC with acceptable performance.

Q: What about the known issue with this update, namely "you may be unable to copy and paste files between Windows 7 and Windows XP Mode (or any other virtual machine)."?
What does "may" mean? The workaround described is not really ideal for us, so considering that VPC2007 didn't have this problem, it would be nice if this version didn't either.
Speaking of which, XP Mode aside, is the new VPC actually an upgrade over VPC2007? If so, in what ways?
So after installing, I ran XP for a while, then made sure I shut down. Then in the VHD settings, I converted the HDD from a differencing VDD to a single merged dynamically expanding one. But now XP Mode can't start any longer?
Windows Virtual PC is a big fail. I installed XP Mode. It completed successfully and auto publish is enabled, I have checked the registry to make sure my app is not blacklisted, put the shortcut in All users Start menu, logged out and hibernated yet my Start menu in Windows 7 only contains shortcuts to XP Mode and WVPC. Not a single shortcut to any app under an "XP Mode Applications" folder as I see in screenshots. Auto publish is a broken mess. Tried uninstalling, reinstalling but to no avail.
I have installed, but cannot update XP Mode (as it cannot activate as the Key included is "not a legal key/already activated". What can be done about this, as I wouldn't want to run just a 30-day "trial" of XP mode. I also don't have a "XP Mode" nor "Virtual PC folder in All Programs after installing per directions on the web site, and had to change permissions to get the VHD out of "read only mode". Any help? email= james at jamwheat.com
I am looking forward to the addition of supporting 64 bit guest machines so that I would be able to demostrate something without have to carrying around two machines.
For when Windows Virtual PC will support x64 platform? I am sick of using VMWare and other software ...
Is it possible to force Virtual PC to not use HAV?
I use VPC only for testing things under XPMode; I use Virtualbox (Linux guest) a lot more, so i'd like VPC not to monopolise on it while it could be much more useful for Virtualbox.

The change to the hardware requirement made using the Virtual XP mode possible for me! Allowing a licensed copy of XP w/SP3 on it made things so much easier. Thanks!
How can i have "windows XP for windows 7 - Home Premium"???
I cant even get xp mode to download . Toshiba s500 running wind7 pro 32 bit
XP was OK for me and my enterprise. Why does Microsoft implement such a complicated and ressource consuming (i mean human and natural ressources) mess only to give us what we need and want?
Why cant they admit that Windows Vista and Windows 7 is a mess in many many details?
Start over with selling and supporting XP again, and you will make more money.
Remember that you cannot blow every ballon as much as you like, at one moment it make BUFFF, and you will loose completely. Microsoft is playing with the fire and approaching the point where customer patience makes BUFFF and they will look for alternatives.
