I need to see the progress of disk defrag like in xp where can I check
You don't really "need" to.
It's a design decision to remove the graphical display, because for one
thing it is meaningless, and for another, there aren't enough pixels on your
screen to correctly display the disk sectors and files. So any display
would be a "fudge" to look pretty, rather than a meaningful indication of
fragmentation.
Vista is designed to defrag invisibly, and it works perfectly well. It is
kicked off automatically once per week, and runs only when your computer is
idle (at the lowest processor and I/O priorities) so it can't impact on your
usage of the PC.
And it works fine. Honestly, you really can just forget about
fragmentation.
If you don't believe me, just use your computer normally for a few weeks.
Then run 'defrag c: /a' and see if there is any significant fragmentation.
I bet there won't be.
