Thank you again, Rock. About:

> Signing what agreement, I'm not sure what you're talking about.

The WGA update comes with an agreement that one has to 'sign' (that is,
click a button that says "I agree").

After reading the EULA I understood that, with the WGA update, Microsoft
links some ID's of my hardware with the ID of my version of Windows XP. This
link will be stablished as the way to recognize if a particular version of
Windows XP is being installed in other computers, which is forbidden.

Again I try to explain my concern:
In my view, Microsoft's procedure is flawed because they didn't think that
my computer can have future changes in parts of its hardware. By 2010 I will
have a different motherboard or hard disk, with ID's that are different to
the ID's of my previous hardware, as registered in Microsoft's files dating
back to 2007.

Once the WGA update is installed, any future activation of the same Windows
XP could be hindered because of an obsolete hardware ID - software ID link. I
imagine that if I change my hard disk and reinstall Windows XP, I will
receive a warning from MS saying that I have an illegal copy of Windows XP.
Why? Because according to their files, my version of Windows XP should match
another hard disk.

I want the freedom to change some parts of my hardware in the future; it
still will be the same computer, but will Microsoft recognize it as such?

> If you don't want to install the WGA update, don't.

I also understood that if I don't install the WGA update, I won't get some
important future updates. That's why this is for me a lose-lose situation and
I am seeking help.

OK, thanks, but sometimes people that work for MS write something here too.
There is Mike Brannigan in this same thread. He works for MS.
However your comments help me too, Rock, and I appreciate them.

Thank you also, Bob I. Your comment is very much like Rock's first one in
what it says. I understand that I didn't 'buy' the software. But as a MS
consumer with limited rights to use their software, I want to know my options
before I install or not the WGA update. I have already said its agreement
should be friendlier to the legal MS consumers who have paid some money to
use their products. I think Microsoft can build a better mousetrap than this
one.

Take care and thanks again.
