In migrating from Microsoft Windows XP to Windows 7 using USMT 4 and KACE KBOX2100, I ran into an issue with the migration of the user’s wallpapers.  I searched online for a complete solution, but couldn't find one so I present the following:

To properly migrate the wallpaper I had to make edits to the MigApp.xml, MigUser.xml and themeui-dl.man for both x86 and amd64.  I recommend using Notepad++ for editing xml files: http://notepad-plus-plus.org/

MigApp.xml:

In between the sections  “<!-- RealPlayer Basic 11 -->“ and “<!-- Windows Live -->” add the following code:

<migration urlid="http://www.microsoft.com/migration/externalUserDocs"> 
  <!-- This component migrates wallpaper settings --> 
  <component type="System" context="User"> 
    <displayName>Wallpapers</displayName> 
    <role role="Settings"> 
      <rules> 
        <include> 
          <objectSet> 
            <pattern type="Registry">HKCU\Control Panel\Desktop [Pattern]</pattern> 
            <pattern type="Registry">HKCU\Control Panel\Desktop [PatternUpgrade]</pattern> 
            <pattern type="Registry">HKCU\Control Panel\Desktop [TileWallpaper]</pattern> 
            <pattern type="Registry">HKCU\Control Panel\Desktop [WallPaper]</pattern> 
            <pattern type="Registry">HKCU\Control Panel\Desktop [WallpaperStyle]</pattern> 
            <pattern type="Registry">HKCU\Software\Microsoft\Windows\CurrentVersion\Themes [SetupVersion]</pattern> 
            <pattern type="Registry">HKCU\Software\Microsoft\Internet Explorer\Desktop\General [BackupWallpaper]</pattern> 
            <pattern type="Registry">HKCU\Software\Microsoft\Internet Explorer\Desktop\General [TileWallpaper]</pattern> 
            <pattern type="Registry">HKCU\Software\Microsoft\Internet Explorer\Desktop\General [Wallpaper]</pattern> 
            <pattern type="Registry">HKCU\Software\Microsoft\Internet Explorer\Desktop\General [WallpaperFileTime]</pattern> 
            <pattern type="Registry">HKCU\Software\Microsoft\Internet Explorer\Desktop\General [WallpaperLocalFileTime]</pattern> 
            <pattern type="Registry">HKCU\Software\Microsoft\Internet Explorer\Desktop\General [WallpaperStyle]</pattern> 
            <content filter="MigXmlHelper.ExtractSingleFile(NULL, NULL)"> 
              <objectSet> 
                <pattern type="Registry">HKCU\Control Panel\Desktop [WallPaper]</pattern> 
                <pattern type="Registry">HKCU\Software\Microsoft\Internet Explorer\Desktop\General [BackupWallpaper]</pattern> 
                <pattern type="Registry">HKCU\Software\Microsoft\Internet Explorer\Desktop\General [Wallpaper]</pattern> 
              </objectSet> 
            </content> 
          </objectSet> 
        </include> 
      </rules> 
    </role> 
  </component>

  <!-- This component migrates wallpaper files --> 
  <component type="Documents" context="System"> 
    <displayName>Move JPG and BMP</displayName> 
    <role role="Data"> 
      <rules> 
        <include> 
          <objectSet> 
            <pattern type="File"> %windir% [*.bmp]</pattern> 
            <pattern type="File"> %windir%\web\wallpaper [*.jpg]</pattern> 
            <pattern type="File"> %windir%\web\wallpaper [*.bmp]</pattern> 
          </objectSet> 
        </include> 
      </rules> 
    </role> 
  </component> 
</migration>

MigUser.xml:

In between the sections “<!-- This component migrates Shared Favorites -->” and “<!-- This component migrates Quick Launch files -->” add the following code:

 <!-- This component migrates Internet Explorer Wallpapers -->
    <component type="System" context="User">
        <displayName _locID="miguser.iewallpaper">Internet Explorer Wallpaper</displayName>
        <paths>
            <path type="File">%CSIDL_APPDATA%\Microsoft\Internet Explorer</path>
        </paths>
        <role role="Settings">
            <detects>
                <detect>
                    <condition>MigXmlHelper.DoesObjectExist("File","%CSIDL_APPDATA%\Microsoft\Internet Explorer")</condition>
                </detect>
            </detects>
            <rules>
                <include filter='MigXmlHelper.IgnoreIrrelevantLinks()'>
                    <objectSet>
                        <pattern type="File">%CSIDL_APPDATA%\Microsoft\Internet Explorer\* [*]</pattern>
                    </objectSet>
                </include>
                <merge script="MigXmlHelper.DestinationPriority()">
                    <objectSet>
                        <pattern type="File">%CSIDL_APPDATA%\Microsoft\Internet Explorer [*.bmp]</pattern>
                    </objectSet>
                </merge>
            </rules>
        </role>
    </component>

themeui-dl.man:

Change this line:

<pattern type="Registry">HKCU\Software\Microsoft\Windows\CurrentVersion\Themes\LastTheme [ThemeFile]</pattern>

To this:

<pattern type="Registry">HKCU\Software\Microsoft\Windows\CurrentVersion\Themes\LastTheme [Wallpaper]</pattern>

Following these procedures migrates the user's wallpaper from Windows XP to 7 while maintaining the aero desktop theme.

Make sure to edit both the x86 and amd64 versions of the files!  Also, it's a good idea to backup your original files just in kace...
