I think one annoying error that I’ve suffered with on Microsoft Vista with Oracle 11g is the
nmefwmi.exe error. I got a message from Microsoft saying it’s fixed. They refer to Oracle Bug #6596234, but it’s really fixed in the Oracle 11g patch (184.108.40.206.0). Therefore, don’t waste your time looking for a one-off patch on metalink.
You can ignore this message on Vista that says refer to Bug #6596234 … by the way it’s actually under patch #6890831. Only the Linux and Solaris ports are available as of today.
