Scripting

Hi All,

Don't know if this is the proper place for adding scripts?
But if not, maybe someone can help me put it in the right place? :-)


We have a managed environent and release software updates (using MSI) to our clients on a monthly basis.
The same time we release our software updates we also wanted to install available updates from our WSUS server.

The problem we had was that the Windows Update Client downloads and then installs them on a given time of day.
We wanted WSUS updates to be installed with all the other software updates released the current month.


We're currently using these 2 scripts to make sure all the updates available are downloaded and installed from our WSUS server. This has worked extremly well for us. Installation of WSUS updates are now triggered the same way we install our other software installations.



Thought I might share for once instead of just poping in to "steal" tips and tricks ;-)
Hope this can come in handy!
