Windows 7 Update Failure

After updating Parallels yesterday, the DirectX acceleration was "Enable" on my Windows 7.
But, I found that Windows 7 always needs to update.
When I update Windows 7 and reboot it, I found it needs to update again and again.
It seems to update failure, although Windows 7 shows ok.

Now, the Direct X acceleration on my Windows 7 is not available again.
