SYMPTOMS
When you try to use your Microsoft IntelliMouse Optical Wheel Mouse, the scroll wheel does not work as expected.



CAUSE
This behavior may occur if both of the following conditions are true:


 * You connected your mouse to your computer through the PS/2 port.

-and-
 * You installed Windows by using Remote Installation Services (RIS) and an image that was created by using the Riprep tool.



RESOLUTION
To work around this issue, use one of the following methods.

Method 1: Set the Wheel Detection Option

 * 1) Click Start, and then click Run.
 * 2) In the Open box, type main.cpl, and then click OK.
 * 3) Click the Hardware tab, click Microsoft IntelliMouse Optical Wheel Mouse, and then click Properties.
 * 4) Click the Advanced Settings tab, and then click Assume wheel is present in the Wheel Detection list.
 * 5) Click OK, and then click OK.

Method 2: Delete the EnableWheelDetection DWord Value
If you are maintaining the RIS image, work around this problem for all Riprep images that are deployed from the server. To do this, delete the EnableWheelDetection DWord value in the Setupreg.hiv file in the installation image on the RIS server.

NOTE: This change is to the flat image hive (.hiv) file and not the hive file in the RIPREP image.

To do this, delete the following registry value from the Setupreg.hiv file:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Services\I8042PRT\Parameters\EnableWheelDetection

You can use the following script to delete this key from Setupreg.hiv: reg.exe LOAD HKLM\t Path_to_setupreg.hiv_in_the_flat_image reg.exe DELETE HKLM\t\ControlSet001\Services\i8042prt\Parameters /v EnableWheelDetection /f reg.exe UNLOAD HKLM\t

Method 3: Set the EnableWheelDetection DWord Value in the Registry
For multiple computers, you can set the Wheel Detection option to Assume wheel is present by modifying the registry.

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Follow these steps, and then quit Registry Editor:  Click Start, click Run, type regedit, and then click OK. Locate and then click the following value in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ACPI\PNP0F13\DEVICE GUID\Device Parameters\EnableWheelDetection

 On the Edit menu, click Modify. Type 2, and then press ENTER.

(In step 2,  is the globally unique identifier [GUID] for your mouse.)

If a PNP0F06 key exists under the ACPI key, set EnableWheelDetection to 2 for this key. Follow these steps, and then quit Registry Editor:  Click Start, click Run, type regedit, and then click OK.</li> Locate and then click the following value in the registry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ACPI\PNP0F06\DEVICE GUID\Device Parameters\EnableWheelDetection

</li> On the Edit menu, click Modify.</li> Type 2, and then press ENTER.</li></ol>

(In step 2,  is the GUID for your mouse.)

NOTE: You must restart Windows for these changes to take effect.
