Issues with XP SP3

[GW]

I have just upgraded to SP3, but met up with some problems associated with
keys.
First, I have Chinese and Japanese input method installed. But after the
upgrade, the ctrl + space and alt + shift key for swiching between input
methods no longer work in some (not all) programs, e.g. Microsoft Word,
Internet Explorer. But they do work with Notepad.
Second, the Google Desktop search bar (the bar that appears when hitting
"ctrl" twice") no longer appears after hitting "ctrl" twice.
I am sure this is with SP3 since no similar problem occurs until I installed
it on my HP laptop. I have successfully replicated it with another HP laptop,
btw.

Well it is not really due to Japanese IME, and actually the other laptop I
replicated the same result on has only Chinese installed.
The Google desktop application is also up-to-date.
Now I have already uninstalled XP SP3, and the problems are gone.
The SP3 experience is perhaps the worst nightmire ever. Besides the problem
in this thread, I have also met problems such as I can't rotate the
orientation of screen with ATI Driver version lower than 8.5, etc.

Why? Please state in detail what exact reasons you needed to get a new
version of Windows on?
