You need to Set() the permissions back. 
use Win32::Perms;
my $dir = new Win32::Perms('c:/temp')||return 0;
$dir -> Remove ('everyone');
$dir -> Set(); # here is where we apply the new perms
$dir -> Dump;

That should do the trick for you.

My Win32::Perms->Dump() doesn't display account permissions twice. I am using ActiveState Perl v5.6.0 on Windows 2000. What version and platform are you using? Maybe if you post your output of Dump(), I would have an idea about it.
