BUG #14320: Turn on user-prompts on error on Windows.

In general turn off error prompts. This is where the process waits for
user-input on any error/warning. In past, we turned on prompts on Windows.
However, for client processes, we capture the error messages in the UI and
for the server-processes, prompts can cause unnecessary interruptions. Hence
we turn off prompts all together.
