"In special cases, charges that are ordinarily incurred for support calls may be
canceled if a Microsoft Support Professional determines that a specific update will
resolve your problem. The usual support costs will apply to additional support
questions and issues that do not qualify for the specific update in question."
Well, it seems that waving charges related to a patch is at the sole discretion of a
support "person",
who in my experience is often unable to determine what is patch-related and what
constitutes "additional" support.
"Let's reinstall the OS" is paid, additional support, AFAIK.
Any pos/neg experiences?
