While running Windows Update I am getting 0x66A error code. It keeps on appearing. I tried to re-run the update a number of time but that did not helped much. What are the possible options available that can help me to fix the issue. I think the update is important and cannot be ignored. I found on web that the update is related to some .NET Framework 2.0 Service Pack 2.
