Microsoft routinely releases security updates on the second Tuesday of each month (Patch Tuesday), but can provide them whenever a new update is urgently required to prevent a newly discovered or prevalent exploit targeting Windows users.
The SUS download is a little larger than 32MB and is available from Microsoft's Software Update Services Web site: (I run SUS on a Windows 2003 server in my small office/home office--SOHO--network.) Running the executable download installs SUS and launches the Web configuration console.
You can configure SUS remotely, but the user who configures SUS must be a local administrator on the SUS server, even in a domain or AD environment.
The optimum SUS setup for most networks is configuring client computers to force updates on a regular schedule.
These updates, which are summarized below, will take effect on September 15, 2016.
