Then you wait - to do it right, all clients must check in, remove the update if necessary, then check in AGAIN to confirm they have removed the update When the installed count is 0 it's been removed from every machine that had it and the no status count is also 0 all clients have checked in you can then DECLINE the update and run the wizard or script to get it out of WSUS.
