HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{6BF52A52-394A-11d3-B153-00C04F79FAA6}\InprocServer32

</li> In the right pane, double-click the (Default) entry.</li> In the Value data box, change the value from the old value to the new value, and then click OK:

Old value: C:\WINDOWS\system32\wmp.dll

New value: C:\WINDOWS\system32\wmp1.dll

</li> Quit Registry Editor, and then restart the computer.</li></ol>

Restore the registry entry to its original value after you complete the installation of Windows XP SP2. To do this, follow these steps:  Click Start, click Run, type regedit in the Open box, and then click OK.</li> Locate and then click the following subkey in the registry:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{6BF52A52-394A-11d3-B153-00C04F79FAA6}\InprocServer32

</li> In the right pane, double-click the (Default) entry.</li> In the Value data box, change the value from the old value to the new value, and then click OK:

Workaround for an unattended installation
Note Before you perform an unattended installation by using the following steps, make sure that your computer is using a VIA processor. If the unattended installation is not completed successfully, contact the computer manufacturer for help.

To work around this issue if you want to apply an unattended installation to a computer that has a VIA Processor, follow these steps:  Create the following folder structure for your $OEM$ folder:

C:\$OEM$\$1\Sysprep\I386\$OEM$

</li> Use a text editor, such as Notepad, to create a file that contains the following text:

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{6BF52A52-394A-11d3-B153-00C04F79FAA6}\InprocServer32]

@=&quot;C:\\WINDOWS\\system32\\wmp1.dll&quot;

</li> Save the file as Rename.reg in the C:\$OEM$\$1\Sysprep folder.</li> <li>Use any text editor, such as Notepad, to add the following text to the [Unattended] section of the Unattend.txt file in the Sysprep folder:

[GuiRunOnce]

Command0 = &quot;c:\Windows\regedit /s C:\Sysprep\Rename.reg&quot;

</li> <li>Create a file that contains the following text:

[Commands]

&quot;C:\Windows\regedit /s c:\sysprep\Original.reg&quot;

</li> <li>Save the file as Cmdlines.txt in the C:\$OEM$\$1\Sysprep\I386\$OEM$ folder.</li> <li>Create a file that contains the following text:

REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{6BF52A52-394A-11d3-B153-00C04F79FAA6}\InprocServer32]

@=&quot;C:\\WINDOWS\\system32\\wmp.dll&quot;

</li> <li>Save the file as Original.reg in the C:\$OEM$\$1\Sysprep folder.</li> <li>Create a file that contains the following text:

[Unattended]

InstallFilesPath = &quot;C:\Sysprep\i386&quot;

[GuiRunOnce]

Note You must include a blank [GUIRunOnce] section in your Sysprep.inf file.</li> <li>Save the file as Sysprep.inf in the C:\$OEM$\$1\Sysprep folder.</li></ol>
