Q. How to forcibly install a patch on all WSUS clients immediately?
A. To install the patches immediately, you have to do the following: Set a deadline on patch in the WSUS admin UI for any date in the past. This will cause all clients to immediately download and install the patch, rebooting if needed, as soon as they receive it on next scan) From the command line on each client, run "wuauclt.exe /detectnow". This will cause AU to immediately do that "next scan" on that client.
می توان این روش را با اسکریپت هم انجام داد .
