Applying manually security patches...

Hi,

We need daily to proccess various PCs by reinstalling windows 98. We need
also to apply security patches to all of them, but the process of using
windows update is too slow for us. I downloaded all the patches applicable
to our basic installation. My idea is run all of them from a batch. But when
running them, each patch at the end asks for restarting the PC. But when you
use Windows Update it applies all the patches in one run, and only at the
end it asks for restarting. How to do that? Which command line parameter it
uses?

Thanks in advance
Faustino
