Vista - VPC2004 Additions and Windows 7

I understand VPC2004 itself doesn't work (or is it just "unsupported"?) in Windows
7. There shouldn't be a problem using the VPC2004 Virtual Machine Additions under
VPC2007 in w7, correct? I'm looking to migrate one of my machines from XP to w7/64,
and don't want to lose the ability to create new VMs based on that older set of
additions.

I guess I'm a little unclear, as well, on whether I even need to (or should?)
install VPC2007 in that OS, or if it just comes with the system. It appears I
should be grabbing the latest from
http://www.microsoft.com/windows/vir.../download.aspx ?

Thanks... Karl

Which one you use depends upon the processor, Karl.
If the processor supports virtualization and that feature has been
enabled in the BIOS, then run Windows Virtual PC on Win7.

If it doesn't, use VPC 2007, which is what I'm using. And, the Virtual
Additions are built into VPC 2K7, so one does not have to install them
as in VPC 2K4.

To see if the processor supports virtualization click these links on the
middle right hand side of the page you posted:

AMD CPUs to ship with virtualization capabilities

BTW, the RTM of Windows VPC is now on Technet/MSDN so it should be on
the MS Download Center soon. As to MS' definition of 'soon' ... <w>

just need to enable it in BIOS, and I'll be good there. Why is this the deciding
factor -- does WVPC with virtualization significantly outperform VPC2007?
Hmmmm, I always had to install them in 2007 whenever I built a VM. But there were
some, like older DOS/9x VMs, that just ran better with the 2004 additions IIRC.
Appreciate that link.
Heh, right. Thanks much...

Assuming the MB/BIOS allows you to enable this, then you should be ok.
Significantly? Depends, on what you're doing.

You do get USB, and you get the ability to take advantage of mutliple
cores/CPUs. Since WindowsVPC is based on Virtual Server, instead of
VPC, if you run multiple VMs they can each run in a separate thread on
a separate core. With VPC2007, all VMs ran in 1 thread on 1 core.

I'd have to think. Assuming the actual performance isn't bogged down, as one thread
("Windows Virtual PC on Windows 7 very slow network access") seemed to indicate.
