I'm sorry Rick, but all that the loss-of-functionality scenarios require is
that when you use the Vista upgrade edition you can only do a custom
installation. The upgrade install option is disabled. It does NOT mean
that the user must use a full edition. Notice that the Upgrade Matrix is
all about...well...UPGRADE editions.
The green dots in the upgrade matrix indicate when either an upgrade or
custom install may be performed. The yellow dots mean that only a custom
install may be done.
All entries in the upgrade matrix may be performed with an upgrade edition.
None require a full edition.
