It sounds like you had a bad experience; but it's not universal. I installed
this update on 64 bit Vista and I didn't have any problem at all. I'm no fan
of Activation, and I will bag it, any chance I get. But so far, both this
fix and WGA have been totally hassle-free, on all my Vista machines (64 bit
and 32 bit; desktop and laptop).

Well, you need to install the correct download, which matches your version
of Windows! That's kind of obvious.

If this happened to every Vista user, it would be all over Slashdot, the
Register, Neowin, CNET and a thousand other IT news outlets. I'm ready to
bag activation on philosophical and political grounds; but I have to admit,
with Vista running on 5 or 6 machines, it just hasn't caused me any
practical problems. The WGA part is barely noticeable.
It sounds like something went wrong in your particular case, but
(fortunately) it's far from the universal experience.
