Windows XP Mode is a free pre-installed virtual machine running on Virtual PC in Windows 7. See the tutorial on our sister site Seven Forums: Windows XP Mode - Install and Setup - Windows 7 Help Forums In this tutorial, I will show how to use Windows XP Mode virtual hard disk to create a virtual machine in Windows 10 using Hyper-V. Microsoft calls this virtualized instance of Windows XP “Windows XP Mode,” and distributes it in the Windows Virtual PC format. If you prefer to use VMware Workstation or VMware Player instead of Virtual PC, follow instructions below. First, download Windows XP Mode from Microsoft.
What are VHDs?
Virtual Hard Disks (abbreviated to VHDs) are files on the physical machine that store the hard disk contents of a Virtual Machine (VM). Each VHD file is treated as a separate hard disk by Windows® Virtual PC (WVPC).
The Virtual Hard Disk file format is an open standard. For the curious, the specifications of VHD file format can be found here: http://technet.microsoft.com/en-us/virtualserver/bb676673.aspx. As can be seen, the format is quite straightforward and is completely agnostic to the virtualization technology in use and to the host and guest operating systems.
- There are many unofficial Windows XP ISO file in numerous of websites. So to create a Windows XP virtual machine, one has to download that ISO and make that virtual hard disk manually. Is there a way to get a pre-build official Windows XP virtual machine from official Microsoft website?
- This download comes as a pre-configured VHD and helps you evaluate the new features of Windows Server 2003 R2, the most productive infrastructure platform for powering connected applications, networks, and Web services from the workgroup to the dat.
- The reason of providing VHD images is to help developers to test their applications or websites on different version of internet explorer supplied with each OS. It has been four months since Windows 7 Service Pack 1 released and today Microsoft has released first VHD image of Windows 7 SP1 along with Windows Vista Sp2 and XP sp3 VHD images.

WVPC, Windows® XP Mode, Microsoft Hyper-V®, Virtual PC 2007® and other Microsoft’s virtualization solutions use the VHD format.
Types of VHDs
There are three types of Virtual Hard Disks: fixed disks, dynamically expanding disks and differencing disks.
Fixed disks take up all the space that the VHD is allowed to have up front. For instance, if you create a fixed disk of size 64GB, the VHD file will occupy 64GB of hard disk space right from the time of creation, and its size will never vary.
Dynamically expanding disks (also called sparse disks) increase in size to take up space as required. The size specified when creating a dynamically expanding disk indicates the maximum size that the disk is allowed to grow to. For instance, if you create a dynamically expanding disk of size 64GB, the VHD file might initially occupy only a few KB. It will slowly grow upon usage to occupy up to the maximum size specified (64GB). Note however, that the guest operating system will be made to believe it has the full 64GB right from the start.
Differencing disks are a little different. They merely save the changes to the VHD relative to a base disk. Differencing disks are always linked to a dynamically expanding disk or a fixed disk, either directly or through one or more other differencing disks. To understand differencing disks, let us say you create a fixed disk with Windows® XP installed on it. Now if you create a differencing disk and install Microsoft Office® on this, the differencing disk will contain mainly* the content of the hard disk locations changed by the installation of Microsoft Office®, which will be the locations containing the new files and any modifications to existing files.
* I say “mainly” since the operating system will make changes to the hard disk too, as part of its regular operation (writing to the page file, for instance).
To illustrate this point, take a look at the figure below. There are two VMs using two differencing disks that branch from the same base disk.
Figure 1. Two VMs on a single host with their Differencing disks sharing the same Base disk
The changes made by VM#1 are saved in its differencing disk (depicted as orange blocks) and the changes made by VM#2 are saved in VM#2’s differencing disk (depicted as green blocks). Wherever there is no data in the differencing disk (i.e., a blank space between the orange blocks), the data will be automatically fetched from the base disk. Thus, VM#1 will see the resultant hard disk as a mix of orange and blue blocks. Neither VM#1 nor VM#2 will be able to see the changes made by the other since these changes are on different differencing disks, and both think they have their own copy of the base disk.
The base reference disk is called the “parent” of the differencing disk, and the differencing disk is called its “child”. As you might have guessed, a differencing disk is unusable without the parent disk. What’s more, any change made to the parent will potentially invalidate the child since the reference file is now different. This is why it is recommended to choose a base parent disk and mark it “read-only” for good.

And what’s the size of the differencing disk, you ask? Well, the differencing disk grows in size as required, and inherits the maximum size from its parent disk.
Using VHDs
Needless to say, all types of VHDs will have the “.vhd” extension. The maximum size of the VHDs supported by Windows Virtual PC is 127GB.
Dynamically expanding disks and differencing disks are by far the most commonly used VHD types.
The biggest advantage of differencing disks is that you can have as many child disks as you like from a single parent disk. So if you need 5 virtual machines with Windows® XP with each configured differently, you can simply create a single sparse/fixed VHD with Windows® XP installed on it and then create 5 differencing disks from this. So that’s saving 4 times the space needed to install Windows® XP!

Indeed, this is the approach used in Windows® XP Mode! Well, let me explain that in detail.
VHDs and Windows XP Mode
When a user installs the Windows® XP Mode package, a dynamically expanding VHD is placed on the system. This is the base VHD, which contains a sys-prepped copy of Windows XP SP3®. The base VHD has already been marked read-only, and what’s more, it’s permissions have been set in such a way that only TrustedInstaller can make changes to it (and the only change TrustedInstaller will make is to remove the file on uninstall). This takes care of having a pristine base VHD that won’t be modified (Figure 2).
When you click on the “Windows XP Mode” link on the start menu after installing the VHD, VPC detects that the VHD has been installed and launches a wizard that takes basic information needed to create the VM. As you can see, this wizard is different from the wizard used to create a VM – for starters, this wizard has already decided to create a differencing disk with the Windows XP Mode VHD as the parent; it merely asks you where you want to place the differencing disk.
Each user on the computer will be shown this wizard and will have a new differencing disk created for them. This way, every user has access to their personal copy of Windows XP without taking up extra space for the Windows XP install.
Figure 2. Different VMs sharing the same parent VHD in Windows® XP Mode
This above example is a typical use-case for differencing disks. You can have a similar setup on your machine(s) with Windows® Vista and/or Windows® 7 VMs too. Of course, it is strongly advised that you optimize the base VHD before calling it pristine and marking it read-only. Ah, we haven’t discussed VHD optimizations yet, have we? Well, considering that topic is big enough to merit its own post, I’ll save that for another day. Stay tuned for more on VHDs!

Introduction
Disk2vhd is a utility that creates VHD (Virtual Hard Disk - Microsoft'sVirtual Machine disk format) versions of physical disks for use inMicrosoft Virtual PC or Microsoft Hyper-V virtual machines (VMs). Thedifference between Disk2vhd and other physical-to-virtual tools is thatyou can run Disk2vhd on a system that’s online. Disk2vhd uses Windows'Volume Snapshot capability, introduced in Windows XP, to createconsistent point-in-time snapshots of the volumes you want to include ina conversion. You can even have Disk2vhd create the VHDs on localvolumes, even ones being converted (though performance is better whenthe VHD is on a disk different than ones being converted).
The Disk2vhd user interface lists the volumes present on the system:
It will create one VHD for each disk on which selected volumes reside.It preserves the partitioning information of the disk, but only copiesthe data contents for volumes on the disk that are selected. Thisenables you to capture just system volumes and exclude data volumes, forexample.
Virtual PC supports a maximum virtual disk size of 127GB. Ifyou create a VHD from a larger disk it will not be accessible from aVirtual PC VM.
To use VHDs produced by Disk2vhd, create a VM with the desiredcharacteristics and add the VHDs to the VM's configuration as IDE disks.On first boot, a VM booting a captured copy of Windows will detect theVM's hardware and automatically install drivers, if present in theimage. If the required drivers are not present, install them via theVirtual PC or Hyper-V integration components. You can also attach toVHDs using the Windows 7 or Windows Server 2008 R2 Disk Management orDiskpart utilities.
Do not attach to VHDs on the same system on which you createdthem if you plan on booting from them. If you do so, Windows willassign the VHD a new disk signature to avoid a collision with thesignature of the VHD’s source disk. Windows references disks in theboot configuration database (BCD) by disk signature, so when thathappens Windows booted in a VM will fail to locate the boot disk.
Disk2vhd does not support the conversion of volumes with Bitlocker enabled. If you wish to create a VHD for such a volume, turn off Bitlocker and wait for the volume to be fully decrypted first.
Disk2vhd runs on Windows Vista, Windows Server 2008, and higher,including x64 systems.
