Even so, the disk defragmentation program used to run in an active
window. I'm having the same problem, and I even check my processes to
see if it could be running, but it isn't. I also started cmd.exe as an
administrator and attempted to run defrag.exe with arguments to
defragment files in all volumes, defragment whole files regardless of
size, forces the defragmenter if remaining space was low, and to run
verbose mode, which is meant to give the user a detailed analysis.
Nothing happened. If someone else having the problem would like to give
it a go and see if it works, just search for cmd.exe from Windows
Explorer, right-click it and select Run as Administrator, and then type
"defrag -c -w -f -v" and press enter. Otherwise, Vista's defragmenter
is not working in either the foreground or background.
