Computer Safety - Operating System Updates and Patches

What are these?
Every computer uses software called an Operating System (OS) to manage basic tasks such as storing and retrieving data, interfacing with other programs and hardware, and more. As systems are used and new technologies are released, the OS requires software patches and upgrades to resolve any security issues that are discovered and to improve functionality.

The most commonly used operating systems today are Microsoft's Windows and Apple's Macintosh OS. Both have different versions of the OS (for example: XP, 2000, ME for Windows and 10.x, 9.x for Macintosh) so you may find that some updates only effect specific versions. Software programs such as Word, Excel, Firefox, Internet Explorer, and Symantec can also require updates and patches from time to time. Since the OS or program has to contact its parent company, your computer must be online to get new information about updates.

Updating Your Operating System
Both Windows and the Mac OS are typically set to look for updates automatically, but it is important to regularly check the computers you use to make sure this function is running properly since viruses and other malicious programs can attempt to block updates. CUIT on the Morningside campus provides online tutorials and information on running updates for Windows and Macintosh. Please keep in mind that using updates require an Administrative log on to the computer, so you may not have access to run them on a department system that is managed by CUbhis or other IT staff.

Keep your operating system up to date
This site includes information for both Windows and Macintosh. CUMC Faculty, Staff and Students should contact the Information Commons with any issues or questions regarding updates.

Updating software programs
To update a specific program, there's usually a "check for updates" option under its Help menu or you can search the company's web site. You may also be prompted by the software when it opens or closes if an automatic update feature is enabled.

CUbhis Managed Computers
Computers that are managed by CUbhis receive updates automatically. If you have a unique user name and password for a computer that is owned by your department, you will most likely not have access to install updates and patches. Your logon does not give sufficient access to the computer to change parts of the OS as required for updates - this is a protective measure since viruses, spyware and unauthorized programs often try to change parts of the OS as well.

More about updates and patches:

• Microsoft updates are categorized by the severity of any security risk they patch, if they are released for this purpose. It is very important that updates marked critical be installed as soon as possible to protect your computer and data from malicious people or programs. Even if you are running other security programs such as antivirus, antispyware and firewalls, an exploit related to a critical upgrade could cause problems on your computer. Details regarding individual Microsoft updates can be found at:

• Microsoft releases most of its updates and patches on the second Tuesday of every month. If your Windows Update feature is turned on you should receive these automatically.
• Microsoft Service Packs are large bundles of upgrades and patches. Since they must make a number of changes to the Operating System, it is a good idea to back up your data before installing a Service Pack.
• CUbhis posts information about important updates and security issues for all Operating Systems and commonly used programs in our News and Announcements column on our home page.
• OS and program updates are often not actually required to continue running the computer or program, some may add features that don't necessarily care about. If you do not have the time to find out why the update was released, it is best that you install it anyway in case it fixes a security issue.
