Software security updates
Security problems are often discovered in a wide range of software applications. In order to fix these problems the software manufacturers typically make available a software security update that you can download and install.
The most imporant variety of software security updates are those for your operating system, Microsoft Windows or MacOS, for example. Instructions are provided below on how to run the updates for any Windows and MacOS computer.
Windows updates are automatically deployed each month for Windows computers that are connected to the main Trinity data network in offices and labs. IT Services use Microsoft System Center Configuration Manager (SCCM) to manage these automatic updates, and there is more information on this below.
Note that updates are periodically also made available for individual applications, such as Flash and Java, and it is always advised that you enable or run any update features within the applications to ensure the security of your device.
Please note: Computers which are running older, unsupported operating systems, or which fail to have the required operating system updates installed, or which do not have the required anti-virus software installed, may be disconnected from the network as an IT security measure.
IT Services uses Microsoft's System Center Configuration Manager (SCCM) to automate the process of deploying Windows software updates to Windows PCs connected to the main Trinity data network in offices and labs. Windows updates are deployed monthly, starting on the third Monday of the month, but there may be occasions when an emergency update needs to be deployed.
Installing the SCCM Agent
1. Launch the Windows 'Run' dialog box by holding down the Windows key on the keyboard and hitting R, or by choosing Run from the Start menu.
2. In the 'Run' dialog box, beside 'Open:' enter the following and click OK:
The installation is silent, meaning that you will see no dialog boxes. It can take about 5-10 minutes to complete the installation.
Installing monthly updates
Each month SCCM will give you the option to install the required updates immediately or to defer the update to a time that's more convenient to you - this can be helpful as most updates require that you restart your computer to complete the update process. Please note that you must install the updates by the deadline specified in the SCCM Software Center, otherwise the update service will take place automatically, including any necessary system reboot.
- When a Windows update is available to your computer a pop-up message will appear stating 'Software changes are required', as follows:
- To proceed to install the updates you must click on this pop-up message, and this will open a Software Center box listing information about 'software changes'. If you do not wish to install the updates then the pop-up will disappear after approximately 15 seconds. After this you can access the Software Center box by clicking the icon show below on your taskbar, and then selecting View Required Software
- An example of the Software Center box is shown below - you must select one of the radio buttons and click OK to proceed, or Remind me later to postpone the update. See below for a description of each option listed here.
If you select Apply all required changes now then the updates will be installed in the background while you are working, without impacting on any applications that are running. If a restart of your computer is necessary then you will be prompted to do so after the installation has completed.
If you choose Apply all required changes outside my scheduled business hours then SCCM will attempt to install all required changes outside of your business hours (click the link to define these hours) as long as you leave your computer running. It is recommend to check the Restart my computer automatically if needed option to avoid being prompted to restart during the next day.
Should you choose to do nothing then the software updates will be installed automatically once the installation deadline, quoted at the top of the box, has been reached. If a restart is required then your system will prompt you after the updates are installed.
Clicking on the 'Restart required' pop-up will display a restart menu, allowing you to choose when to restart the computer.
Please follow the instructions for your operating system below in order to run Windows update.
**Running a PC that is connected to the main Trinity network in offices and labs is a slight exception. Instead of following instruction listed below, please follow the instructions listed above in the Automatic Windows updates for computers on main Trinity data network (SCCM) section on this page. Setting up your PC to obtain automatic updates via the SCCM service will ensure you receive Windows Updates which ahve been tested prior to being made available by IT Services.
