Internet Explorer 6 Re-factoring and Footprint Reduction
Other Key Re-factored Components for Footprint Reduction
Conclusion
Many components in Windows XP Embedded Service Pack 2 Feature Pack 2007 are re-factored to reduce unnecessary dependencies. The paper discusses key component re-factoring and provides the procedure for removing unneeded components from the Windows XP Embedded run-time image when upgrading an existing target device configuration file from Windows XP Embedded Service Pack 2 to Windows XP Embedded Service Pack 2 Feature Pack 2007.
Many Windows XP Embedded Service Pack 2 Feature Pack 2007 components are enhanced to remove unused dependencies or to factor out binaries that benefit other features. Key components re-factored in Windows XP Embedded Service Pack 2 Feature Pack 2007 include:

For new Windows XP Embedded Service Pack 2 Feature Pack 2007 target device configurations, the check dependencies command in Target Designer automatically reduces the Windows XP Embedded run-time image footprint as components are added. No special procedures are needed.
In contrast, Target Designer does not automatically remove now-obsolete dependencies when upgrading an existing target device configuration (.slx) file from Windows XP Embedded Service Pack 2 to Windows XP Embedded Service Pack 2 Feature Pack 2007. For target device configuration upgrades, manually remove unnecessary dependencies to construct a run-time image with a smaller footprint.
For example, in Windows XP Embedded Service Pack 2 Feature Pack 2007, the WMI Core component no longer depends on the Volume Shadow Copy Service component. When upgrading an existing target device configuration, use the enhanced Windows XP Embedded Service Pack 2 Feature Pack 2007 component database package to reduce the run-time image footprint by manually removing the Volume Shadow Copy Service Administrator component and all of its associated dependencies as follows:
+Volume Shadow Copy Service
++Indexing Service
+++Filter Mime Messages for the Indexing Service
++Removable Storage Service
After manually removing the Volume Shadow Copy Service component and the components on which it depends, run the Target Designer check dependencies command to ensure that the components are safely removed. If the removed components reappear in the configuration after check dependencies executes, then other features or components depend on them.
The following procedure specifies how to identify and remove obsolete dependencies when upgrading an existing target device configuration file from Windows XP Embedded Service Pack 2 to Windows XP Embedded Service Pack 2 Feature Pack 2007.
No automated tool is provided to remove unnecessary component dependences when upgrading an existing target device configuration file from Windows XP Embedded Service Pack 2 to Windows XP Embedded Service Pack 2 Feature Pack 2007.
However, Windows XP Embedded Service Pack 2 Feature Pack 2007 includes a new command-line tool, XPECMD, to query component dependencies in the Windows XP Embedded component database. Use XPECMD to identify and remove obsolete component dependencies.
XPECMD is written in VBScript and requires Microsoft Windows Script Host (CScript) to run. XPECMD is located in the Program Files\Windows Embedded\bin folder. For more information on how to use XPECMD, please refer to Windows XP Embedded Service Pack 2 Feature Pack 2007 Help.
For each component listed in Refactored Components, first use XPECMD to identify its previous and current dependencies, then manually remove obsolete dependencies.
To use XPECMD to Identify and Remove Obsolete Dependencies for a Component
Using the Command Prompt, run the following command to generate the dependency tree for the component at its previous revision number:
XPECMD> DEPTREE /4 ‘comp:component name|revision number’where component name is the name of the component in Target Designer and where revision number is the revision number in the previous configuration, for example, R2890 for Windows XP Embedded Service Pack 2.
Using the Command Prompt, run the following command to generate the dependency tree for the component at the Windows XP Embedded Service Pack 2 Feature Pack 2007 revision number (that is, R3333):
XPECMD> DEPTREE /4 ‘comp:component name|R3333’where component name is the name of the component in Target Designer
Examine the difference in the dependency trees to identify changes in the component dependencies introduced in the upgrade to Windows XP Embedded Service Pack 2 Feature Pack 2007. In Target Designer, manually remove those dependencies rendered obsolete in Windows XP Embedded Service Pack 2 Feature Pack 2007.
Removed dependencies may themselves be dependent on other components. For each removed component, repeat steps 1 through 3 until all unnecessary component dependencies are eliminated from the configuration.
After completing the procedure for all relevant components, run Check Dependencies in Target Designer to confirm that the dependencies have been removed properly. If other components in the target configuration depend on the removed components, Target Designer automatically adds them back into the target configuration.
The procedure for identifying obsolete components described in Using XPECMD to Identify and Remove Obsolete Dependencies may be tedious and time consuming. To simplify the task of reducing the run-time image footprint when upgrading an existing target device configuration file, the following table provides a list of key components with dependencies removed from, and newly-added to, Windows XP Embedded Service Pack 2 Feature Pack 2007
Please note that this is not a complete list of components, but it does indicate where most footprint reduction activity is concentrated. This list is generated using the XPECMD tool as described in Using XPECMD to Identify and Remove Obsolete Dependencies.

Internet Explorer 6 is the component perhaps most significantly re-factored for footprint reduction. Let's examine the key changes to the Internet Explorer 6 component and what other features benefit significantly in footprint reduction from this effort.
Many features in Windows XP Embedded depend on Internet Explorer, including the following:
- .NET Framework 1.1
- Help and Support Services
- HTML Rendering Engine
- IMAPI - CD Burning
- Internet Connection Wizard
- Microsoft Vector Graphics Rendering (VML)
- Outlook Express
- Shell Namespace Extensions
- Soap Client Runtime
- Windows .Net Messenger
- Windows Media Player 10.0
- Windows Media Player 9.0
- Windows Movie Maker
Those features have either a static or delay load dependency on one or more files of the dozens owned by the Internet Explorer 6 component. Those dependent files were removed from the Internet Explorer component and made into their own individual Primitive components. The files removed from Internet Explorer component include the following:
- ACTXPRXY.DLL
- Cryptdlg.dll
- DXTRANS.DLL
- HLINK.DLL
- Iedkcs32.dll
- IEINFO5.OCX
- IEXPLORE.EXE
- IMGUTIL.DLL
- INETCPL.CPL
- INSENG.DLL
- JSPROXY.DLL
- MSHTA.EXE
- MSIDENT.DLL
- MSIDNTLD.DLL
- MSRATING.DLL
Internet Explorer 6 now depends on these new primitives. Other higher-level features such as .NET Framework 1.1 and Help and Support Services now also depend on just a few of these Primitive components instead of on the Internet Explorer 6 component itself. The result is a reduced run-time image footprint. For full Internet Explorer 6 functionality add the Internet Explorer 6 component to your target configuration.
Depending upon the features selected in the target configuration, certain platform build scenarios without a fully functional Internet Explorer 6 feature may achieve a footprint reduction of from 3% to over 50%.
Other key components are re-factored for the benefits of other features, including those in the following table:
| Re-factored Component | Beneficiary Components |
|---|---|
Volume Shadow Copy |
WMI Core |
Simple Network Management Protocol (SNMP) |
IIS FTP Server, IIS Web Server |
Outlook Express |
Dialer Application, IIS Internet Manager |
Help and Support Services |
Remote Assistance Channel (for SMS Client scenario) |
Administration Support Tools |
Users Control Panel |
The beneficiary components listed above no longer depend on the re-factored components, but instead depend on only a few primitives factored out of the original components.
The procedures and information provided in this white paper can significantly reduce the run-time image footprint when upgrading an existing target device configuration file from Windows XP Embedded Service Pack 2 to Windows XP Embedded Service Pack 2 Feature Pack 2007.
