    I am running Windows 7 Ultimate in a VM on the following Macbook Pro:

    Model Name: MacBook Pro
    Model Identifier: MacBookPro2,1
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.33 GHz
    Number Of Processors: 1
    Total Number Of Cores: 2
    L2 Cache: 4 MB
    Memory: 3 GB
    Bus Speed: 667 MHz
    Boot ROM Version: MBP21.00A5.B08
    SMC Version (system): 1.14f5

    My VM is configured as follows:
    1 CPU, 1024MB memory, 256MB graphics memory, Enable 3D acceleration is on, Enable vertical synchronization is on.

    Prior to the 9308 update, this VM had a Windows Experience Index score of 2.9.
    After the update, the score dropped to 2.0.

    Thinking that enabling vertical synchronization might be the issue, I turned this off and then, I reran the assessment.

    With vertical synchronization turned off, the Windows Experience Index went up to 3.9.
