Windows Search stopped working. The event log shows the entry:

The Windows Search service terminated with the following service-specific error:
Class not registered

If I attempt to start the service manually, a MessageBox pops up and tells me to check the Event Viewer (see above entry), and references a service-specific code error -2147221164.

I cannot search for docs from the taskbar, and cannot search within Outlook through messages, etc.

Any help is appreciated. Thanks.
