Hi Suemarie,
Locate within Microsoft updates when the latest Silverlight update was.This has been happening ever since Microsoft did an update on Silverlight.
- Control Panel >> Windows Update >> select View Update History
- Next select To remove an update, see Installed Updates
- Locate the most recent Silverlight, select it to uninstall.
Before taking the above step did you make a backup of the Registry?Before contacting you, I followed the instructions from here: http://social.technet.microsoft.com/...w7itprogeneral
Click Start and type regedit and press the Enter button.
Navigate to HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate
Delete all values with this 0x80070057. Then run the the following fix it tool.

Reboot the computer and verify that the problem has been resolved.
The WindowsUpdate is missing from the string.
What date did you edit the registry on?
