CT Update updates Microsoft Windows 2000 to Microsoft's current operating systems such as Microsoft Server 2008. CT Update creates an image on a CD or DVD with the necessary updates. Once the updates are copied to the disc, the end user runs updateinstaller (an executable) and the updates are installed. This software will create an account with the necessary permissions to install updates and reboots the workstation automatically. Once the reboot occurs, the account is removed.
CT Update supports proxy servers. This is one of the many reason that Windows Updates fail.
