MDT 2010 and USTMT 4.0 Hard Link Migration

One of the most exciting features for deploying a Windows XP client to Windows 7,sits around the ability to create a hardlink during a REFRESH scenario with MDT 2010.

In order to leverage USMT 4.0 in MDT 2010, you must first install the latest Windows Automated Installation Kit for Windows 7.

For more information on the Windows Automated Installation Kit, go here: http://technet.microsoft.com/en-us/library/dd349343(WS.10).aspx

Jeremy Chapman has an excellent video demonstrating how this works: http://edge.technet.com/Media/User-State-Migration-with-Windows-7/

What I really like about hardlinks it doesn’t migrate the user’s data out to the Network, meaning faster deployment times. So, instead of moving files to a protected location on the hard disk, the files aren’t transferred at all, just the paths to them are updated. This is a very cool feature that Microsoft has to offer us to help us facilitate our migration efforts from Windows XP to Windows 7.

This means the install and settings transfer happens much faster, because the files aren’t transferred at all, just the paths to them are updated.  It’s really cool, and means you can have a fresh install of Win7, with all your XP files and settings, completed in short amount of time. Of course, you still need to install the OS. But still…very cool…

So, how do I get USMT hardlinks to work in MDT Lite Touch Installation Environment? When you install MDT 2010 and create your Deployment Share, MDT will create a folder called USMT and copy the necessary USMT files into that folder. If you refresh the machine (by starting Litetouch.vbs from the running OS), MDT 2010 by default uses hardlinks.

I suggest the following read on USMT with MDT 2010 by Tim Minter.

VMware E1000 Nic Drivers, WinPE, and Adding NIC Drivers with DISM

DISM.exe is a new command line tool included in the Windows Automated Installation Kit (Windows AIK) 2.0. You can use DISM to service Windows images, both WIM and VHD files. This is a useful tool that can be used to add/remove device drivers, OS Packages, hotfixes, etc.

I recently came across an occurrence where I needed to add VMWare NIC drivers to my WinPE image. The new Windows 7 WAIK no longer has the PEIMG tool, which was used with the WAIK’s predecessor to inject drivers into the boot image. We now use the DISM.

When PXE booting to my VM, I realized my WinPE did not have the correct NIC drivers installed.

DISM Tool Notes

  • Multiple drivers can be added on one command line if you specify a folder instead of an .inf file.  Use the /recurse option.
  • The command to inject drivers into WinPE w/ DISM are demonstrated below:
  • To install an unsigned driver, use the /ForceUnsigned to override the requirement that drivers installed on x64 based computers must have a digital signature.
  • Dism.exe /unmount-WIM /MountDir:C:\Mount /Commit  (Note – The /commit option is very important!)

Here is what the WinPE Image will look like after the NIC drivers are injected with DISM.

For those using the new VMWare NIC model e1000, WinPE 2.1 supports the new VMWare NIC model e1000. It is recommended to use this NIC Model with your virtual machine. http://h18000.www1.hp.com/products/servers/management/rdp/knowledgebase/00000192.html

IEEE 802.1X authentication protocol support for WinPE

Microsoft has released hotfixes that now add 802.1x support to both WinPE 2.1 and WinPE 3.0. Here are the links to the hotfixes.

WinPE 2.1: http://support.microsoft.com/kb/975483

WinPE 3.0 (Windows 7 & Server 2008 R2): http://support.microsoft.com/kb/972831

Step by Step Instructions to Inject the update using DISM.

1) Once you have downloaded the update, extract the files to your deployment server. In this example, I created a folder on my E:\ called 802PE.

2) Mount the LiteTouchPE_x86.wim using DISM: DISM /Mount-WIM /WIMFile:E:\DeploymentShare$\Boot\LiteTouchPE_x86.WIM /index:1 /MountDir:E:\Mount


3) Inject the package: DISM /Image:E:\Mount /LogPath:AddPackage.log /Add-Package /PackagePath:E:\802PE\Windows6.1-KB972831-x86.cab

4) Unmount and Commit your changes: DISM /Unmount-WIM /Commit /MountDir:E:\Mount
5) As an additional step you can validate the package was installed successfully: DISM /Image:E:\Mount /Get-Packages (Note: When you add the package in step 3 it should tell you, “The operation completed successfully” if the package injected with no errors.)

Configuring Default User Settings – Full Update for Windows 7 and Windows Server 2008 R2

I’ve received some emails in my inbox lately about configuring Windows 7 Default User Settings on the Core Image. Instead of re-inventing the wheel, check out this blog posted by Michael Murgolo from the DeploymentGuys.
