Activaton of a upgrade using a clean install

[...winston]

Reasoning with someone reading between the lines is futile.
No mention of dual booting is present or inferred only that a valid license is required.
You've a valid license for XP(still in use), a valid install of RC1 to use and replace per Msft's approval to install an upgrade version of Vista(now in use)....what more clarification is necessary ?

Since you've also mentioned a line about a fairly sizeable installed Window base company...it would seem that volume licensing would be in play(if not, your company needs a new IT manager soon). Volume licensing contractual requirements can be modified with supplements and/or addendums, or new contracts to modify or even limit the EULA.

: Mike, I should explain that I agree wholeheartedly with what you are saying:
:
: (1) As written, the EULA does not allow dual-booting (the upgraded and
: un-upgraded versions) from an upgrade license;
:
: (2) People have an obligation to follow the EULA whether or not the software
: actually requires them to. (It looks like most or all releases of Vista
: have the same install procedure, which allows some things other than what
: the particular EULA actually permits. These might be useful for rescuing
: situations where the license is valid but the software can't easily verify
: it; but they do not warrant violating the EULA.)
:
: The question I was speculating about is whether Microsoft actually intended
: for the EULA to work this way, since many manufacturers' upgrade EULAs work
: quite differently, and there have already been other updates to the Vista
: EULA to permit things that were originally prohibited. I will be contacting
: Microsoft to see if they've had anything further to say about it.

And I would argue that a single computer, with both versions installed but
not usable at the same time, would not violate this. The user is just
exercising his right to take one out of use and use the other.

Anyhow, I've submitted a question to Microsoft through my employer. We
are a fair-sized customer (maybe 10,000 Windows and Office licenses) so
they'll probably answer.

The license agreement specifically mentions installation. It doesn't matter
that you can't run both at the same time, both can't be installed at the
same time.
