Update and patch

Last updated: February 2, 2024
Audience: All UW


The majority of data breaches and incidents involving malware infections occur because of out-of-date applications or unpatched operating system (OS) vulnerabilities. Maintaining a current patch level for your personal or UW-owned desktop computer, laptops, and other devices is critical for securing your personal and UW’s institutional information.


Patching is sometimes easier said than done. For UW-owned devices or personally owned devices used to access UW systems and data, identify who is responsible for patching the operating system and applications. The accountable person — whether it is you, your departmental IT support person, or a third party — should carefully evaluate the following when implementing a patching strategy:

  • Is the technology or application too old be patched?
  • If your system cannot be patched, can it be updated?
  • Is there a risk associated with patching? For example, will patching break the system (e.g. make the system not work, decrease functionality)?
  • Do you have an obligation (grant, contract, law, or regulation) that requires you to patch your system in order to protect the data on the system?

Things to Do

See the Information Security Guideline for more information.

Below is a non-inclusive list of resource for patching. Consult with your IT support person or the vendor for specifics on how to patch your technology or applications.

Please note that the list of operating systems, applications, browsers, and associated programs on this page is not exhaustive. It is important to run regular checks on any other applications running on your computer or device as well.
