Most updates can be completed at your convenience and do not impact how you use your computer or software. However, occasionally an update may require an action once it is installed or may impact how you use an application. In these situations, you will receive an email with detailed information from U-M Information and Technology Services.
We recommend logging off to allow updates to install at least once a week.
About Software & Security Updates
All updates are tested for compatibility and satisfactory performance. Significant updates are released to a beta testers group prior to release to all devices.
Update Release Schedule
Regular software updates are released weekly to both Windows and Mac devices at the following times:
- Mac — Thursday between 6:30–8:30 p.m.
- Windows — Thursday between 6:30–9:30 p.m.
Occasionally updates will be released outside of the normal schedule. For example, updates addressing severe security vulnerabilities are released as soon as they are available.
Types of Updates
There are two types of updates:
- Required updates have an installation deadline. The update will install automatically if not completed by the deadline. (e.g., security updates)
- Available updates may be installed at any convenient time. While you may choose not to install optional updates, outdated software may not be supported. (e.g., most software updates)
