Upgrade Vista Home Premium to Vista Business using FULL Business C

[planetearth]

My friend got an excellent deal on the FULL Vista Business CD when CompUSA
was going out of sale. Since then, he bought a new Dell laptop with Vista
Home Premium on it, and just wants to *upgrade* to Vista Business.
He does NOT want to wipe Home Premium to replace it with Business, since the
laptop has all the drivers and MS Works (which he wants to upgrade to Office
Standard 2007 using the "upgrade" version).
Can he use the full version of Vista Business to just upgrade Vista Home
premium? As I recall, this wasn't always an option with older versions of
Windows: if you had the "full" version on CD, you couldn't upgrade from it;
you could only wipe and replace.
Thanks!

Hi,

Sorry, but that is not possible. The only upgrade possible from Home Premium
is to the Ultimate edition. The reason is because the Home Premium edition
includes media components whereas the Business version doesn't. To install
the Business edition you will need to perform a clean install.

Thanks, Dwarf. I was afraid of that.
Does MS document this anywyhere so that I can show him? I saw a table
showing the upgrade options from Windows 2000 and XP, but nothing between
versions of Vista.

Hi
That would be a downgrade you can not downgrade from Home Premium to
Business .
Home Permium has to be upgraded to Ultimate !!
If you want Business you have to clean install it .
To confirm this put the Business DVD in while you are in windows Premium and
try to install it you will see the upgrade option is grad out .
Upgrade path is Premium to Ultimate
Business to Ultimate
Home Basic can be upgraded to Business or Premium or Ultimate .
Do a web search you will see .
{And i do not think MSWorks is a valid upgrade path to Office 2007
with a {upgrade disk}
I think it has to be something like Office 2000 or 2003
i do not know this for a fact}
Other people may have there ideas on this part !!
Good Luck

Thanks, Jerry.
According to MS, "Microsoft Works 6.0–10 [and] Microsoft Works suite
2000–2006 or later" are qualifying products for upgrade to Office Standard
2007.
I wouldn't have thought so either, and I was going to ask in another
newsgroup, just to be sure.

Don't confuse upgrading the software with upgrading the license. Upgrading
the license means buying an upgrade edition of Vista and using it to replace
the existing Windows with the upgrade edition. That can be done to replace
Vista Home Premium with Vista Business but you still cannot upgrade the
software (keep your apps and files in place). Upgrading between Vista Home
editions and Vista Business is one of those cases where you have to do a
custom installation. However, that doesn't matter since your copy of Vista
Business is a standard license rather than an upgrade.

Hmmm...now I'm a bit confused.
First, I just found out the CD my friend has is a Vista Business *Upgrade*
CD. I thought he had the FULL version CD, but he only has the UPGRADE CD.
However, from what I thought I understood here, Vista Business is not an
upgrade option from Vista Home Premium, because of some of the software on
Home Premium.
(I'm trying not to confuse "license" with "software", but if he has the CD,
they're pretty much one and the same. He didn't just buy a license to
upgrade--he bought the upgrade software CD itself.)
So, can he *upgrade* Vista Home Premium to Vista Business?
If he *can't* upgrade and decides to buy the FULL version (for a clean
install), what happens to the *license* for the copy of Vista Home Premium
that came with the new Dell laptop? I'm assuming it would no longer be used
(unless someone restored the laptop from a restore CD made before wiping the
drive).
Thanks again for all your help--I'm just trying to get this straight so I
can tell him.

There is no "upgrade cd" for Vista like there is for XP (I know you meant to
say "dvd"). There are only upgrade edition and standard edition product
keys.

Your VB dvd is a just a standard Vista dvd. Vista dvds are all the same.
It is the product key that identifies to Vista Setup.exe the edition of
Vista and the license as "upgrade".

That product key, when entered, will cause Vista setup to switch to its
"upgrade" installation routines. At that point Setup will either require
the user to be running Setup from within existing Windows (x86 dvds) or it
will search for an installation of existing Windows (x64 dvds).

Either way, the upgrade option (meaning your apps and files will be
preserved) will be disabled and only the custom option will be available
when the existing Windows is Vista Home Basic or Vista Home Premium and the
product key is for Vista Business.

The fact that it is an upgrade product key makes no difference in how Vista
gets installed. The option to upgrade the software is either available or
not depending on which new edition is replacing which existing edition and
is the same regardless of the type of product key being used, upgrade or
standard.

The Premium license dies (it can only be used on that computer).

To answer the other question, please read the Vista EULA. When you use an
upgrade edition license you must supercede another license that is eligible
for upgrade to Vista. Usually it is the OEM license for the software that
is already installed on the computer. Once that license is superceded it
may not be used again. Period.

However, there is no requirement to supercede the OEM license if the user
owns a different license that is also eligible for upgrade to Vista and
wishes to assign that license to be the one superceded. This comes into
play when the user wants to do a parallel installation of Vista (dual boot)
so he can continue to use the OEM copy as well.

So what happens to the OEM license depends on the user. If it is the only
license available to be superceded then it is the one that goes kaput.
