is it safe to install window xp patches that are already installed

[Guest]

i have some users that will need X patches prior to being hooked up with Inet
access. all the needed xp patches has been downloaded to an executable and
will be put on cd. will there be a problem if they installed patches that
have already be installed? thanks

Updates that are still in the original file format never wear out,
you can reopen them and install as many times as needed.
