What is the schedule for applying patches to Windows machines in CS?Automatic updates
Each machine in the CS Windows domain is set up to automatically download and install patches that Microsoft deems critical (in other words, security related). As patches become available they will be downloaded by each machine. Every Thursday morning at approximately 3:00 am, each computer running Windows will install any new patches that have been downloaded. If any of the patches requires a reboot, the machine will reboot when the installation is completed.
