Can't install saved updates

Hi,

My computer just tried downloading a bunch of updates, and it wasnt going so
well, so I turned off my shaw secure in order for the updates to come through.

It went through a bit of a hick up, so I ended up selecting "save updates to
disk".
I know have a folder of a bunch of updates, but have no clue as to how to
install them.

Do I just double click?? There is no know file extension either.

I also went back onto the actual updates site and thought I would just click
to download and install again, but the page will only show the "history" of
my downloads, showing the files that were downloaded but did not completely
install, and will not allow me to choose to download and install them again.

(kind of silly if you ask me..)

Thanks in advance for any help
Tammie
