does Windows 7 come with something like Virtual PC built in?
I have an i7 which is suppose to be great with virtualization and I wanted to try it out. Is there a specific app I should get that takes advantage of a 64-bit OS?
You can download Virtual PC - http://www.microsoft.com/windows/virtual-pc/ which now has Windows XP mode built in to it so that it is very easy to virtualise. Only down side is that it is only at RC stage so it may change.
Personally, I still prefer VMware Workstation! http://www.vmware.com/products/ws/ However, Virtual pc is free!
No, Windows 7 does not provide built-in support for running virtual machines. It does have built-in support for mounting Virtual PC disk files (.vhd) but that only allows you to treat them as data drives.
Windows Virtual PC does require hardware virtualization support, which you should have, and allows you to create and run virtual images. Windows XP mode is a separate product download (and requires Windows Virtual PC) that allows you to run a virtual and seamless Windows XP environment for legacy applications. You don't need to install Windows XP mode if you just want to create and run virutal machines.
You can also use VMWare (which is not free) and Sun's VirtualBox (which is free). Both of these will use hardware virtualization if present, but don't require it like Windows Virtual PC. I currently use VirtualBox since my current machine doesn't support hardware virtualization.
it supports .vhd files by default, take a look here http://www.hanselman.com/blog/LessVirtualMoreMachineWindows7AndTheMagicOfBootToVHD.aspx
and a video demonstration here :http://www.microsoft.com/downloads/details.aspx?familyid=80EDE31D-3509-407B-A896-0BEEA8705589&displaylang=en
Just for the sake of completeness, I'd like to recommend the use of VirtualBox:
No, Windows 7 does not come with a Virtual Machine built-in. There's still a plethora of free and good VMs to download though, such as Virtual PC or VirtualBox.
There is also the Virtual XP Mode which runs on the same backend as Virtual PC with some added niceties. However, it has to be downloaded separately.
Also Windows 7 includes the option to directly boot from VHD files (which is what Virtual PC uses and VirtualBox can use as the format for virtual hard disks).
But you have few options
MS Virtual PC
VMware Workstation - my recommendation
You need to download the XP Mode RC.
Windows 7 will come with a built-in virtualization of Windows XP called XP Mode. This should allow you to run some programs which may not work properly with newer versions of Windows.
As MicTech has eluded to, you can also download VirtualPC (or any other virtualization software) as well to give you more options.
