i tried the command you
provided:
%windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks
however, i have reason to beleive that
deleting the prefetch files with a simple
dos command is better than validating
each of them.
i suppose it is like that old saying:
"6 of one or half a dozen of another"
