http://en.wikipedia.org/wiki/LZX_%28algorithm%29LZX was publicly released as an Amiga file archiver in 1995, while the authors (Jonathan Forbes, TomiPoutanen) were studying at the University of Waterloo in Canada. The software was shareware, which was common for compression software at the time. The registered version contained fixes and improvements not available in the evaluation version. In 1997, the authors gave away a free keyfile, which allowed anyone to use the registered version, as they had stopped work on the archiver and stopped accepting registrations. In 1997, Forbes went to work for Microsoft, and Microsoft's cabinetarchiver was enhanced to include the LZX compression method.
Traditional vs. Modular Approach Traditional Modular • OS + Applications in • 1 base image (OS) for 1 image all hardware • Image per hardware type • Apps/drivers delivered as add-ons • Time to integrate new hardware • Easily integrate new hardware • High maintenance • Reduced maintenance • Requires a visit to costs the desktop • Automated build process • Storage requirements • Easy to customise
Traditional Approach • Quick Win • 1 x image per model • high maintenance
Traditional vs. Modular Approach Maintenance Deployment Development Time Traditional Modular

Microsoft Windows Imaging (WIM)• Microsoft’s own image format• File-based disk imaging is a core capability of Windows Vista, Windows 7, Windows 2008• Compared to sector-based formats, a WIM image is file-based
Microsoft Windows Imaging (WIM)• This WIM image format is hardware-agnostic, meaning that you need only one image to address many different hardware configurations.
Microsoft Windows Imaging (WIM)• The WIM image format also lets you store multiple images within one actual file.• For example, Microsoft can ship multiple SKUs in one WIM image file. You store images with and without core applications in a single image file.• Also, you can mark one of the images as bootable, allowing you to start a computer from a disk image contained in a WIM file.
Microsoft Windows Imaging (WIM)• The WIM image format enables compression and single instancing, thus reducing the size of image files significantly.• Single instancing is a technique that allows you to store two or more copies of a file for the space cost of one copy.• For example, if images 1, 2, and 3 all contain file A, single-instancing stores a single copy of the file A and points images 1, 2, and 3 to that copy.
Microsoft Windows Imaging (WIM)• The WIM image format allows you to service an image offline. You can add or delete certain operating system components, patches, and drivers without creating a new image.• Rather than spending a few hours updating an image, which you do now with Microsoft Windows XP, for example, you can update an image in minutes.• For example, to add a patch to a Windows XP image, you must boot the master image, add the patch, and then prepare the image again.• With Windows 7, you can simply service the image offline.
Microsoft Windows Imaging (WIM)• The WIM image format lets you install a disk image on partitions of any size, unlike sector-based image formats that require you to deploy a disk image to a partition thats the same size or larger than the source disk.
Windows Automated Installation Kit• The Windows® Automated Installation Kit (Windows AIK) is a set of tools and documentation that support the configuration and deployment of Windows® operating systems.
Windows Automated Installation Kit• By using Windows AIK, you can automate Windows installations, capture Windows images with ImageX, configure and modify images using Deployment Imaging Servicing and Management (DISM), create Windows PE images, and migrate user profiles and data with the User State Migration Tool (USMT).• Windows AIK also includes the Volume Activation Management Tool (VAMT), which enables IT professionals to automate and centrally manage the volume activation process using a Multiple Activation Key (MAK).
Unattended Windows setup• Unattend.xml• AutoUnattend.xml• As a rule, only answer files named Unattend.xml are used.• However, because some answer files include destructive actions such as disk partitioning, you must rename your Unattend.xml file to Autounattend.xml in the windowsPE and offlineServicing configuration passes. These passes run when you first run Windows PE or Setup.exe.• You typically use the Autounattend.xml file when you use the Windows Setup DVD boot method and supply an answer file on a USB flash drive (UFD) or floppy disk.
Windows PE• Windows PE is a minimal Win32 subsystem with limited services, based on the Windows 7 kernel running in protected mode.• It contains the minimal functionality that you need to run Setup, install Windows from a network share, automate basic processes, and perform hardware validation.• Windows PE was developed specifically to address desktop and server deployment scenarios.
Passes – windowsPE• Configures Windows PE options as well as basic Windows Setup options. These options can include configuring a disk or language settings.
Passes - offlineServicing• Applies updates to a Windows 7 image.• Also applies packages, including software fixes, language packs, and other security updates.
Passes - generalize• The generalize pass runs only if you run sysprep /generalize. In this pass, you can minimally configure Windows 7 as well as configure other settings that must persist on your master image.• The sysprep /generalize command removes system- specific information. For example, the unique SID and other hardware-specific settings are removed from the image.
Passes - specialize• Creates and applies system-specific information.• For example, you can configure: – network settings – international settings – domain information.
Passes - auditSystem• Processes unattended Setup settings while Windows 7 is running in system context, before a user logs on to the computer in audit mode.• The auditSystem pass runs only if you boot in audit mode.
Passes - auditUser• Processes unattended Setup settings after a user logs on to the computer in audit mode.• The auditUser pass runs only if you boot in audit mode.
Passes - oobeSystem• Applies settings to Windows 7 before Windows Welcome starts.
Mini Setup Phase• Windows XP – driver installation – Joining domain – Sysprep.inf was the answer file for this phase• Windows 7 – This phase is now called the ‘Specialize’ pass – (Auto)Unattend.xml is the answer file for this pass
Include custom files• If you wish to include custom files to include in the Windows 7 installation (such as files in the program files, system32 folder, OOBE (Out Of Box Experience) etc.) then make a folder called $OEM$ inside the sources folder.• From there, the following folder structures must apply (many changed from Windows 2000 and Windows XP $OEM$ days) …..
Include custom files• $$ Contains files that Windows Setup copies to the %WINDIR% (for example, C:windows) folder during installation.• $$System32 Contains files that Windows Setup copies to the %WINDIR%System32 folder during installation.
Include custom files• $1 Represents the root of the drive on which you installed Windows (also called the boot partition) and contains files that Windows Setup copies to the boot partition during installation.• $1Pnpdrivers Contains new or updated Plug-and-Play (PnP) drivers. The user specifies the folder name in the Unattend.xml file for unattended installations. For example, this folder might be named $OEM$ Folders$1Pnpdrvs.
Include custom files• drive_lettersubfolder• A subfolder of the drive that contains files that Windows Setup copies to the subfolder during installation. Multiple instances of this type of folder may exist under the $OEM$ Foldersdrive_letter folder, for example, $OEM$ FoldersDMyFolder.• $$SetupScriptsSetupComplete.cmd
Microsoft Deployment Toolkit 2010• Microsoft Deployment Toolkit 2010 (MDT 2010) provides a common console with the comprehensive tools and guidance needed to efficiently manage deployment of Windows 7 and Windows Server 2008 R2.• Microsoft Deployment Toolkit 2010 is the recommended process and toolset to automate desktop and server deployment.• Microsoft Deployment Toolkit 2010 provides detailed guidance and job aids for every organizational role involved with large-scale deployment projects.
MDT 2010 Requirements• Microsoft Management Console (MMC) version 3.0• Microsoft .NET Framework 2.0 or later• Windows PowerShell™ command-line interface (CLI) version 1.0 or 2.0, Community Technology Preview 3 (CTP3) or later• Windows Automated Installation Kit (Windows AIK) for Windows 7
