Since I installed Vista SP1 the main things that I've noticed so far are:
- The 'search' button has vanished from the Start Button menu
- 'Change Icon' no longer works - the changed icon appears correctly in the
shortcut's properties tab, but it doesn't change on the desktop.
The OS seems just as slow as before, if not slower, and SP1 hasn't fixed any
of the bugs that I've had.
