What happens if Microsoft releases a
replacement for a problematic security
update? Do we need to uninstall the previous update before installing the rereleased
update?
I’ve never known it to be necessary to
uninstall the buggy update. Typically, Windows Server Update Services (WSUS) will
either silently reinstall the new version of
the update or prompt you to approve the
update for installation, depending on your
system configuration. In some cases, you
must rerun discovery for Windows to realize that there’s a new version of the update
that needs to be installed on applicable
computers. In rare situations, a bug in an
update’s metadata will cause Windows to
report that computers still need to install the
update even after the update has already
been installed. This problem goes away after Microsoft rereleases the update with
updated metadata.
