As far as I know, they are enabled as part of the Vista Aero and Basic
themes. The only "official" way to get the older style alt-tab dialogue is
to acticate the Windows Classic Theme. But, that may be overkill, for what
you want.
There is an undocumented and unsupported way toget the old behaviour back,
even on Aero. Note that it is, well, undocumented and unsupported - but hey,
it works
Create a DWORD called "AltTabSettings" under
\HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer and set it to value
1. Log out and log back in again. C'est voila.
Overall, the newer look of Alt-tab is not too difficult (IMHO). It's the
stupidly over-hyped WinKey+Tab which I find impossible to use. That
development effort was a useless, empty waste of time.
Hope this helps,
Andrew
